OneDrive can open and print PDFs, add markup in its iOS app, scan new pages into a PDF on mobile, and—where available—recognize text in scanned PDFs. Microsoft’s reviewed guidance does not document built-in OneDrive steps to extract pages from an existing PDF, merge existing PDF files, password-protect a PDF, or compress one. For those jobs, use a separate PDF editor or converter that explicitly supports the operation you need.

OneDrive’s cloud encryption and sharing controls protect files in the service; they do not add a password to the PDF itself. The distinction matters if you plan to download or send the file.

What OneDrive can and cannot do with PDFs

Task OneDrive capability documented by Microsoft
View and print Open a PDF in a browser reader and view or print it; Microsoft says that reader cannot edit PDF contents. Microsoft Support
Mark up The OneDrive iOS app supports notes, text boxes, images, shapes, signatures, drawing, and highlighting. The documented instructions apply to iPhone, iPad, and iPod touch, not all platforms. Microsoft Support
Scan pages into a PDF Android and iOS apps can scan multiple captured pages into one PDF, subject to app-version-specific limits described below. This creates a new PDF; it is not extraction from an existing file. Microsoft Support Microsoft Support
Recognize text in scanned PDFs Microsoft describes OCR that lets users select, search, and copy text in scanned PDFs on Android and iOS. The feature is rolling out, so availability can vary. Microsoft Support
Extract or rearrange pages in an existing PDF Not documented in the reviewed OneDrive guidance. Use a PDF editor that supports page organization. Microsoft Support
Merge existing PDF files Not documented in the reviewed OneDrive guidance. The mobile scan workflow combines newly scanned pages, not existing PDF files. Use a PDF editor that supports merging existing files. Microsoft Support Microsoft Support
Password-protect a PDF Not documented as a OneDrive PDF workflow in the reviewed guidance. Use a tool with PDF password-protection support if the file itself must require a password. Microsoft Support Microsoft Support
Compress a PDF Not documented as a OneDrive feature in the reviewed guidance. Choose a separate converter or PDF editor that specifically provides compression. Microsoft Support

Extract pages from an existing PDF

OneDrive’s browser PDF reader is for viewing and printing, not editing PDF contents. Microsoft’s reviewed documentation does not show a OneDrive command to extract, delete, or rearrange pages in an existing PDF. Open or download the file in a separate PDF editor with page-management features, extract the required pages, and save the result as a new PDF. Confirm the output before replacing or sharing the original.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Do not confuse extraction with scanning: the mobile scanner captures physical pages or images and creates a new PDF rather than pulling pages out of a file already in OneDrive.

Merge PDFs: existing files versus new scans

Merge existing PDF files

The reviewed OneDrive guidance does not document combining existing PDF files stored in your account. Use a separate PDF editor that explicitly supports merging existing PDFs. Before choosing one, check whether it can preserve page order, layout, form fields, and other content important to your files.

Combine newly scanned pages in the mobile app

OneDrive’s mobile scanning workflow can put multiple captured pages into one PDF. Microsoft’s published limits differ by platform and app version:

Password-protecting a PDF is different from OneDrive encryption

Microsoft describes OneDrive as protecting data in transit with TLS and encrypting each stored file at rest with a unique AES256 key. It also says personal OneDrive documents are not public by default and that users can manage sharing permissions. These are protections for files stored and shared through the service; they do not mean a downloaded PDF has a password set on it.

If the recipient must enter a password to open the PDF, use a separate tool with a PDF password-protection feature and verify the resulting file by opening it outside your OneDrive session. If your goal is to limit who can access a cloud copy, review its OneDrive sharing permissions instead. Organizational libraries can have customized features and settings.

Compressing a PDF

The reviewed OneDrive guidance does not document a built-in PDF compression control. Use a PDF editor or converter that explicitly offers compression. Compression may reduce image quality or change how content is represented, so inspect the resulting file—especially scanned pages, diagrams, signatures, and forms—before using it as the replacement.

If you still have the original Office document, Microsoft’s general PDF guidance suggests making edits in the source document when possible or using Word or a third-party conversion tool for PDF changes. The specific conversion guidance does not establish that every tool offers compression, so check its feature list before relying on it.

Choose a separate PDF tool for the exact job

Microsoft points readers toward Word or third-party PDF tools for work beyond its reader, but the reviewed guidance does not compare current vendors, plans, or capabilities. Evaluate the tool against the operation you need rather than assuming that a general PDF editor handles everything.

OneDrive’s documented PDF features and limits can change as its apps and services are updated. The distinctions above reflect Microsoft Support guidance accessed October 7, 2026; they describe what those pages document, not every capability that may exist in other Microsoft products or account configurations.
