The 10 best free PDF converter apps for Android in 2024 depended on the conversion direction: WPS Office or OfficeSuite for Office files, Adobe Scan for paper documents, iLovePDF for broad PDF tools, and Smallpdf, PDFelement, or Adobe Acrobat for PDF-to-Word workflows. “Free” usually meant basic features, quotas, ads, or premium restrictions—not unlimited conversion.
Key takeaways
- PDF conversion means either creating a PDF from another file or exporting an existing PDF to Word, Excel, images, or text.
- WPS Office and OfficeSuite were the strongest 2024 choices for creating PDFs from DOCX, XLSX, and PPTX files.
- Adobe Scan was best suited to scanning receipts, forms, notes, and paper documents into PDFs, not converting an existing PDF into Word.
- iLovePDF offered the broadest historical mix of PDF tools, including PDF-to-Office conversion, JPG-to-PDF, merging, splitting, compression, and password protection.
- Scanned PDFs require OCR for editable text, and OCR can distort tables, columns, handwriting, unusual fonts, and mathematical notation.
- Android’s built-in Print to PDF workflow can create PDFs for free without a third-party app, but it generally cannot turn an existing PDF into an editable Word or Excel file.
10 Best Free PDF Converter Apps for Android in 2024: Which One Should You Choose?
There was no single best free PDF converter for Android in 2024. The right choice depended on whether you needed to create a PDF, scan paper, convert a PDF to Word or Excel, extract images, recognize text with OCR, or edit the result. The shortlist below separates those jobs instead of treating every image-to-PDF utility as a full converter.
What does “PDF converter” mean on Android?
A PDF converter can refer to two opposite workflows. The first creates a PDF from another file, while the second converts an existing PDF into an editable or image-based format.

| OCR conversion | Scanned or image-only PDF → selectable text or editable Office file | Language support, tables, columns, handwriting, scan quality, and manual cleanup |
A photograph saved as a PDF is a useful form of PDF creation, but it is not proof that an app can convert an existing PDF into Word or Excel. Adobe Scan illustrates the difference: the 2024 coverage described Adobe Scan as a scan-to-PDF tool and specifically distinguished it from general existing-PDF conversion. The 2024 app comparison also mixed scanning, PDF creation, and PDF-to-Office conversion under one “PDF converter” label.

Which Android PDF converter is best for each job?
| App or Android tool | Best for | Create PDF | PDF to Word | PDF to Excel | OCR | Free and privacy qualification |
|---|---|---|---|---|---|---|
| WPS Office | Office documents to PDF | Yes | Edition-dependent | Edition-dependent | May vary | Local Office workflows are practical; ads, accounts, cloud features, and premium tools may apply |

1. WPS Office: best for converting Word, Excel, and PowerPoint files to PDF
WPS Office was one of the best Android choices in 2024 for users who already worked with Office-style documents. The 2024 comparison described WPS Office as supporting Word, text, Excel, and PowerPoint documents to PDF, making the app more useful for schoolwork, resumes, reports, spreadsheets, and presentations than a simple photo-to-PDF utility. See the historical WPS Office feature description and WPS Office’s official product page.
WPS Office was a better fit for creating a PDF from DOCX, XLSX, or PPTX than for assuming that every PDF-to-Office feature was free. Ads, account prompts, cloud integration, and premium conversion tools could affect the free experience. Treat WPS Office as a broad office suite with PDF tools, not as proof of unlimited free PDF conversion.
Typical WPS Office workflow
- Open the DOC, DOCX, XLS, XLSX, PPT, or PPTX file.
- Open Tools, File, Share, or the overflow menu, depending on the 2024 app interface.
- Choose Export, Save as, or Convert to PDF.
- Choose a page range or output option if the app provides one.
- Save locally or to cloud storage, then inspect fonts, images, tables, and page breaks.
2. Adobe Scan: best for scanning paper documents into searchable PDFs
Adobe Scan was the strongest fit for receipts, handwritten notes, forms, invoices, and other physical pages. Adobe Scan detects document edges, captures multiple pages, corrects perspective, and uses an OCR-oriented scanning workflow. The 2024 coverage described Adobe Scan as converting captured documents, receipts, photos, and notes into PDFs, but not as a general tool for converting existing PDFs. Adobe’s official Adobe Scan page provides the product context.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Adobe Scan should not be chosen when the starting point is an existing PDF that must become a DOCX or XLSX file. Adobe Scan’s core job is scan-to-PDF. OCR can make scanned content searchable, but searchable does not guarantee clean, editable Word or Excel output.
How to scan paper pages into a PDF
- Open Adobe Scan or another scanner app.
- Point the camera at the page and let edge detection identify the document.
- Capture each page, then crop or rotate pages as needed.
- Reorder pages and run OCR if the app offers that option.
- Save or share the PDF.
- Review every page for missing edges, incorrect rotation, shadows, and unreadable text.
3. iLovePDF: best all-rounder for PDF operations
iLovePDF was the broadest all-purpose candidate in the 2024 shortlist. The historical coverage listed JPG-to-PDF, PDF-to-editable Office formats, image extraction, merging, splitting, compression, rotation, and password protection. The official iLovePDF mobile page is the appropriate place to check the product rather than relying on an old feature list.
The main trade-off is that broad conversion services may process files online. Readers handling tax returns, identity documents, medical records, contracts, payroll records, or confidential business files should determine whether a file leaves the phone before importing it. Free quotas, maximum file sizes, account requirements, and premium restrictions should be checked in the 2024 app version; the supplied research does not establish universal limits.
4. OfficeSuite: best for an Android Office suite with PDF support
OfficeSuite suited users who wanted to view, create, edit, and convert Microsoft Office-compatible files from one Android app. The 2024 coverage said OfficeSuite could convert PDFs to Word, Excel, and ePub, while the Google Play listing described Office file creation, editing, viewing, and conversion to PDF.
Free tools Windows power users keep installed
One-click scans. No signup required.
OfficeSuite’s free and paid editions were materially different. A separate Pro + PDF Google Play listing showed US$29.99 when observed, but that was an edition-specific, date-specific US listing—not a universal 2024 price and not necessarily the price or feature set of the free app. Check the historical Pro + PDF listing context before treating any price as comparable.

5. Smallpdf: best for a straightforward PDF-to-Word attempt
Smallpdf was especially relevant to readers whose main task was converting a PDF to Word. The 2024 coverage also described scanning, PDF creation, galleries, and file merging, although the Android and web product capabilities should not be assumed identical. Smallpdf’s official mobile page identifies the product family.
Smallpdf was primarily cloud-oriented, so internet access and document upload considerations mattered. A free tier could also impose conversion, file-size, or subscription limits. Smallpdf was a reasonable first choice for a non-sensitive, mostly text-based PDF, but it was not automatically the best choice for confidential files, very large documents, or unlimited free conversion.
6. PDFelement: best for conversion plus editing and OCR
PDFelement was the most complete editor-oriented choice in the shortlist. Its Android listing described conversion from PDF to Word, Excel, PowerPoint, text, and multiple image formats, alongside PDF editing and OCR capabilities. The PDFelement Android listing is the source for those product claims, and Wondershare’s Android product page provides the official product context.
PDFelement was not a strong answer to “unlimited free conversion.” Wondershare’s free Android version had fewer features, while advanced conversion and OCR could require payment or an account. Observed 2026 Android prices were US$3.99 weekly, US$19.99 yearly, and US$39.99 perpetual; those prices were observed after 2024 and must not be presented as 2024 prices. The Android purchase page is date-sensitive and region-sensitive.
PDFelement made sense for users who needed conversion, annotation, signing, OCR, and document management together. PDFelement was excessive for someone who only needed to save a gallery image as a PDF.
7. Adobe Acrobat: best for a trusted premium export workflow
Adobe Acrobat was a credible choice for reading, annotating, signing, sharing, and exporting PDFs, but Adobe Acrobat should not be labeled a fully free PDF-to-Word converter. Adobe’s mobile documentation lists viewing, comments, annotations, form filling, signing, and sharing among free functions, while export to other formats, editing, combining, compression, and page organization require premium access. Adobe’s mobile subscription documentation explains the free-versus-premium distinction.
Adobe’s observed US pricing in August 2026 included Export PDF at US$1.99 per month billed annually at US$23.88 per year, PDF Pack at US$9.99 per month billed annually at US$119.88 per year, and Acrobat Pro at US$19.99 per month on an annual commitment. Adobe’s pricing page supplies those current observations, but they are not 2024 prices and can vary by region, billing channel, and promotion.
Acrobat was a better fit for frequent PDF-to-Word or PDF-to-Excel work, OCR, and users already committed to Adobe’s ecosystem than for occasional free image-to-PDF creation.

8. PDF Converter and PDF Maker utility apps: best for basic image-to-PDF jobs
Lightweight PDF Converter and PDF Maker utilities could be convenient for turning photographs, scans, receipts, or several images into one PDF. The 2024 coverage associated these generic utilities with image-to-PDF creation, compression, scanning, reading, and basic editing. The historical list is also a warning: it included two separate entries using the generic name “PDF Converter.”
Because “PDF Converter” is not a unique app identity, a responsible recommendation must include the exact developer, package name, Google Play URL, permissions, update date, and review status from the 2024 listing. The supplied research does not identify those details for one verified utility, so readers should not treat every app with that name as the same product or download an APK from an unverified site.
These utilities were suitable for basic local image-to-PDF work when their permissions and free limits were acceptable. They were poor candidates for assuming reliable PDF-to-Word, PDF-to-Excel, OCR, privacy, or long-term availability without checking the exact listing.
Quick wins for a faster PC:
Repair Windows errors before they cause bigger problemsFix Now →Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →9. Offiwiz PDF Converter: best claimed format breadth, pending verification
Offiwiz PDF Converter appeared in the 2024 coverage as a broad-format utility claiming support for PDF, DOC, PPT, XLS, RTF, ODT, JPG, PNG, Word, text, and other conversions, along with scanning, OCR, reading, and translation. Those claims came from secondary 2024 coverage, not independently verified primary documentation in the supplied research.
Offiwiz was therefore a candidate for readers who wanted many formats in one app, not a recommendation that every claimed conversion preserved layout accurately. Before installing, verify the exact Google Play listing, developer, Android requirement, permissions, free limits, account requirement, cloud handling, and current availability in the reader’s country.
10. Android Print to PDF: best free route when creating a PDF is enough
Android’s built-in Print to PDF workflow was the simplest free alternative when the goal was to create a PDF from a printable image or document. The usual route is Gallery or Photos → three-dot menu or Share → Print → Save as PDF → save icon, although labels vary by manufacturer, source app, Android version, and region. The 2024 coverage documents this Print to PDF alternative.
- Open the image or document.
- Tap Share, More, or the overflow menu.
- Choose Print.
- Select Save as PDF as the printer.
- Tap the PDF or save button.
- Choose a folder and filename, then open the result to verify it.
Print to PDF does not generally convert an existing PDF into editable Word or Excel. The built-in route was best for avoiding ads, accounts, and third-party permissions when PDF creation—not editing or reverse conversion—was the actual requirement.
Do these 3 things before closing this tab:
1Repair Windows errors before they cause bigger problems2Fix the driver behind crashes, sound loss and screen glitches3Clear out junk files and repair common Windows errorsHow should you choose between a text PDF and a scanned PDF?
First determine whether the source PDF contains selectable text. A text-based PDF usually allows text selection and copying, while a scanned or image-only PDF contains page images and requires OCR before the text can be edited. A mixed PDF may contain selectable text on some pages and scans on others.

| PDF type | How to identify it | Likely conversion result | Recommended approach |
|---|---|---|---|
| Text-based PDF | Text can usually be selected and copied | PDF-to-Word or PDF-to-text is generally easier | Use a converter with the required export format, then inspect layout |
| Scanned PDF | Pages behave like images and text cannot be selected | OCR is required; tables and formatting may break | Use OCR-enabled software and proofread the output |
| Mixed PDF | Some pages have selectable text and others do not | Different pages may convert with different accuracy | Convert in sections or check every page individually |
OCR can alter tables, columns, footnotes, handwriting, mathematical notation, unusual fonts, low-resolution scans, and text inside photographs. Adobe’s export documentation includes OCR with paid export functionality, and PDFelement lists OCR and PDF conversion among its advanced capabilities. Adobe’s export documentation and PDFelement’s Android listing support those product distinctions.
How much of each app is actually free?
“Free” had several meanings in the 2024 Android PDF market. An app could be free to download, free for image-to-PDF creation, free for viewing and annotation, limited to a small number of conversions, supported by ads, or free only during a trial. PDF-to-Word, PDF-to-Excel, OCR export, batch processing, editing, compression, and page organization were commonly the features most likely to be restricted.
| Free claim | What the claim really tells you | What it does not prove |
|---|---|---|
| Free download | You can install the app without an upfront payment | Conversion, OCR, export, or editing is unlimited |
| Free PDF creation | You can probably create a PDF from an image or document | An existing PDF can become Word or Excel |
| Free viewer | You can read, and possibly annotate, PDFs | Advanced export or OCR is included |
| Free trial | Premium tools may work temporarily | The feature remains free after the trial ends |
| Free tier | Some operations work without payment | There is no quota, page limit, file-size limit, watermark, ad, or account requirement |
Adobe’s official documentation is a useful example of why the distinction matters: Adobe lists mobile viewing, comments, annotations, form filling, signing, and sharing as free, while export to other formats and several document-management features are premium. Read Adobe’s free and premium feature distinction before treating Acrobat as a free converter.
How do you convert an image to PDF on Android?
The built-in Android Print to PDF method is usually the fastest free route for a gallery image, although the exact labels vary.
- Open the image in Gallery or Photos.
- Tap Share, More, or the three-dot menu.
- Select Print.
- Choose Save as PDF.
- Tap the save button, select a destination, and name the file.
- Open the saved PDF and check its orientation, cropping, and readability.
A dedicated scanner or PDF-maker app is more useful when several pages must be cropped, reordered, compressed, or OCR-processed. Saving an image as a PDF does not automatically make the text inside the image selectable.
How do you convert a Word, Excel, or PowerPoint file to PDF?
WPS Office and OfficeSuite were the most natural 2024 choices for converting Office documents to PDF on Android.
- Open the DOC, DOCX, XLS, XLSX, PPT, or PPTX file in WPS Office, OfficeSuite, or another compatible app.
- Open Tools, File, Share, or the overflow menu.
- Select Export, Save as, or Convert to PDF.
- Choose page range and output options if available.
- Save locally or to cloud storage.
- Check fonts, page breaks, images, tables, hyperlinks, margins, and page orientation before sending the PDF.
When a document contains complex spreadsheets, embedded fonts, charts, or presentation effects, the PDF should be treated as a new output that requires inspection rather than as a guaranteed pixel-perfect copy.

- Open iLovePDF, Smallpdf, PDFelement, Adobe Acrobat, or another app that explicitly lists PDF-to-Word.
- Import the PDF from local storage or cloud storage.
- Choose Export, Convert, or PDF to Word.
- Select DOC or DOCX.
- Enable OCR if the PDF is scanned and the app offers OCR.
- Save or share the output.
- Open the Word file and inspect paragraphs, tables, columns, signatures, forms, images, and page breaks.
Do not suggest bypassing a password-protected PDF. A converter may require the password, refuse the file, allow printing but block editing, or export only permitted pages.
Can Android convert a PDF to Excel accurately?
Android can convert some PDFs to Excel, but table-heavy documents require the most checking because a PDF preserves page appearance rather than the underlying spreadsheet structure. A converter may interpret a table as separate text boxes, individual lines, misaligned columns, an image, or ordinary paragraphs.
PDFelement and some editions of OfficeSuite list PDF-to-Excel workflows, while iLovePDF and other services may provide broad Office conversion. The existence of a PDF-to-Excel button does not guarantee that invoices, forms, merged cells, totals, or multi-column tables will become a usable spreadsheet. Rebuild or verify important formulas and figures manually.
Recommended Free Tools
What are the biggest Android PDF conversion failure modes?
| Problem | Likely cause | Practical response |
|---|---|---|
| OCR produces nonsense | Low resolution, shadows, skew, unusual fonts, handwriting, or unsupported language | Rescan in better light, straighten the page, improve resolution, select the correct language, and proofread |
| Tables break in Word or Excel | PDF page appearance does not encode table structure | Try another converter, export smaller sections, and manually reconstruct or verify the table |
| Conversion is paywalled | PDF-to-Office, OCR, batch processing, or advanced export is premium | Use the free creation workflow for simple jobs or compare the paid feature against the cost of retyping |
| Large file fails | Memory limits, upload timeout, page quota, battery limits, or cloud restrictions | Split or compress the PDF, convert fewer pages, retry on Wi-Fi, or use a desktop tool |
| Output cannot be found | The app saved to its own folder or cloud account | Check the app’s recent files, Downloads, Documents, cloud storage, and Android file manager |
| Watermark appears | Free export tier limitation | Check the preview before submitting or printing; choose a different workflow if the watermark is unacceptable |
| No internet connection | The conversion is cloud-based or account-dependent | Use Android Print to PDF or a verified local workflow for creation; do not assume reverse conversion works offline |
| PDF is password-protected | Editing or copying is restricted | Enter the authorized password or ask the document owner for an unrestricted copy; do not bypass security |
Which PDF converter is best for privacy?
The best privacy-friendly route is a local workflow that keeps the document on the phone, such as Android Print to PDF for printable content, provided the specific app does not upload the file. Cloud conversion may provide stronger OCR or layout processing, but cloud processing means readers must consider internet access, account security, retention, and where sensitive documents are handled.
Use particular caution with identity documents, medical information, legal contracts, tax returns, payroll records, financial statements, and proprietary business files. The supplied 2024 research does not establish a universal on-device or cloud-processing policy for every app in the shortlist, so check the exact app’s privacy documentation and settings before uploading confidential material.
2024 verdict: which app should you install?
| Your job | Best 2024 choice | Why | Important qualification |
|---|---|---|---|
| DOCX, XLSX, or PPTX to PDF | WPS Office or OfficeSuite | Both combine Office-compatible workflows with PDF creation | Free and premium features differ |
| Paper receipts, forms, or notes to PDF | Adobe Scan | Designed around camera capture, page correction, and scan workflows | Not a general existing-PDF-to-Word converter |
| Many PDF operations in one place | iLovePDF | Historical coverage included Office conversion, JPG-to-PDF, merge, split, compression, rotation, and protection | Uploads, quotas, and premium restrictions may apply |
| PDF to Word | Smallpdf, PDFelement, or Adobe Acrobat | Each was associated with PDF export, with different feature and payment models | Scans need OCR; free export is not guaranteed |
| PDF to Excel | PDFelement or a verified Office/PDF suite | These products list or historically describe PDF-to-Excel capability | Complex tables may require manual rebuilding |
| Photo or printable document to PDF without installing an app | Android Print to PDF | Free, usually account-free, and adequate for basic creation | Does not generally reverse-convert PDFs to editable files |
| Conversion plus editing, OCR, signing, and management | PDFelement | Broader editor-oriented feature set | Advanced features are not necessarily free |
The most accurate answer to “what was the best free PDF converter app for Android in 2024?” is therefore conditional. Choose WPS Office or OfficeSuite for Office-to-PDF work, Adobe Scan for paper scanning, iLovePDF for broad PDF operations, and a clearly labeled PDF-to-Word or OCR tool when reverse conversion is the actual task. Always test the output before submitting, signing, printing, or sharing it.
Frequently Asked Questions
Can I convert a PDF to Word for free on Android?
You can convert some PDFs to Word for free on Android, but free access commonly depends on the app, file, quota, and PDF type. Smallpdf, iLovePDF, PDFelement, and Adobe Acrobat were associated with PDF-to-Word workflows in the 2024 coverage, but premium prompts, account requirements, upload requirements, or free-use limits may apply.
Does Adobe Scan convert an existing PDF to Word?
Adobe Scan is primarily a scan-to-PDF app, not a general existing-PDF-to-Word converter. Adobe Scan is suited to capturing paper documents, receipts, notes, and forms and saving them as PDFs; use a PDF export tool when the starting file is already a PDF.
Can Android convert an image to PDF without an app?
Yes. Open the image, choose Share, More, or the overflow menu, select Print, choose Save as PDF, and save the file. Menu names vary by Android version, manufacturer, and source app.
Why does my converted PDF look wrong in Word?
PDFs preserve page appearance rather than a complete editable document structure, so tables, columns, fonts, images, forms, and page breaks can be reconstructed incorrectly. Scanned PDFs also require OCR, which can misread low-resolution text, handwriting, unusual fonts, and mathematical notation.
The Bottom Line
Bottom line: There was no universally best free PDF converter app for Android in 2024. WPS Office and OfficeSuite were the practical choices for Office files, Adobe Scan was the scanning choice, iLovePDF was the broad all-rounder, and Smallpdf, PDFelement, or Adobe Acrobat were better suited to PDF-to-Word workflows—subject to free-tier and premium restrictions.
