For automated URL capture, Chrome Headless has a command-line PDF option; for local HTML or Python scripts, WeasyPrint is another route. The best choice depends on whether you need a one-off file or a repeatable workflow.
Choose the right no-key method
| What you need | Use | What to know |
|---|---|---|
| Save one webpage occasionally | Chrome’s Print dialog | Lets you inspect the print layout and adjust available settings before saving. |
| Automate PDF capture of a URL | Chrome Headless | Runs from the command line and supports a capture timeout. |
| Convert local HTML or generate PDFs from Python | WeasyPrint | Offers a command-line interface and a Python API; unsupported CSS can produce warnings. |
| Use a different headless command-line tool | wkhtmltopdf | The project describes itself as using Qt WebKit; verify its maintenance and compatibility before adopting it for new work. |
These options are not interchangeable rendering engines. They differ in setup, input workflow, and supported page behavior. The available documentation does not establish a controlled speed or fidelity winner, so test the tool against the pages you actually need to convert.
Save a webpage as a PDF in Chrome
For a single page, browser printing is usually the least involved option: it needs no API key, script, or separate conversion service. It is also useful when you want to check the result before keeping it.
- Open the webpage in Chrome and wait for the parts you need to appear.
- Open Print: press Ctrl+P on Windows or Linux, or Command+P on Mac.
- Select a PDF destination, such as Save as PDF, in the print dialog.
- Review the preview and available settings. Check page breaks, margins, and whether backgrounds or other important page elements appear as intended. The controls shown can vary by platform and browser version.
- Save the file and open it to verify the pages that matter.
On Android, Chrome’s documented route is More → Share → Print → Save as PDF; then choose where to save the file. Menu labels and available print controls can differ across versions and devices.

Why the PDF may not look like the screen
A webpage’s print layout can differ from its on-screen layout. A site may apply print-specific styling, and a long page may break across sheets in ways that are not obvious while scrolling. If a background, image, or section is missing, check the preview and the print settings available in your version of Chrome. Do not assume that changing a setting will make every site’s print layout match its screen design; inspect the saved file before relying on it.
Automate a URL-to-PDF conversion with Chrome Headless
Chrome Headless is the command-line choice when a script or scheduled task needs to print a URL without opening the ordinary browser window. The documented basic invocation is:
chrome --headless --print-to-pdf https://example.com/Replace https://example.com/ with the page to capture. Run the command in an environment where Chrome is installed and available as chrome; depending on your installation, you may need to use the path to the Chrome executable. The command invokes Chrome’s PDF printing workflow rather than a third-party API.
Remove printed headers and footers
To omit the print header and footer, add --no-pdf-header-footer:

chrome --headless --print-to-pdf --no-pdf-header-footer https://example.com/Set a maximum wait
Chrome Headless documents --timeout to limit how long capture waits. For example, a 5-second maximum wait can be expressed as:
chrome --headless --print-to-pdf --timeout=5000 https://example.com/A timeout is a maximum wait, not proof that the page has finished rendering. A page that fills in content after its initial load may need a different wait strategy, and time-dependent JavaScript can affect what appears. Chrome’s documentation also describes virtual-time budgeting for such scripts. Test a representative page before using a command across a batch, and verify that its important content appears in the resulting PDF.
Convert local HTML or use Python with WeasyPrint
WeasyPrint provides a command-line interface and a Python API, so it can fit projects that already work with local HTML or Python. A documented Python example converts a URL and writes a PDF:
from weasyprint import HTML
HTML('https://weasyprint.org/').write_pdf('/tmp/file.pdf')Change the URL and destination to suit your page and output location. For a local file, WeasyPrint’s HTML interface can also be used with a filename, for example:

from weasyprint import HTML
HTML(filename='input.html').write_pdf('output.pdf')Its command-line workflow can convert an HTML input to a PDF as well. If your project depends on a particular styling detail, inspect the result and any warnings rather than assuming every CSS property is supported in the same way as a browser.
Account for resources, cookies, and authentication
Converting a local HTML file does not automatically make its linked images, stylesheets, or fonts available: the converter still needs to be able to locate and fetch those resources. Check that paths resolve in the conversion environment and that the rendered PDF includes them.
WeasyPrint’s documented default HTTP client does not support advanced features such as cookies or authentication. A custom URL fetcher can address some cases, but authenticated sites may require additional setup. If a page only displays its content after sign-in or consent, confirm how the converter receives the required state before treating the output as complete.
Handle HTML and CSS as untrusted input carefully
WeasyPrint’s project documentation warns against processing untrusted HTML or CSS without considering security. A service that accepts arbitrary user input should assess the risks of fetching external resources and processing hostile content, and should isolate conversion work appropriately. Do not treat a local conversion library as automatically safe just because it runs on your own machine.

What about wkhtmltopdf?
wkhtmltopdf is another command-line option, and its project describes it as an open-source tool using Qt WebKit. That identifies its rendering engine, but does not establish current compatibility with every modern site. The project’s indexed homepage is older than the Chrome and WeasyPrint documentation considered here, so check its current maintenance status, installation support, and output on your target pages before starting a new dependency on it.
For a new workflow, choose based on your input and environment: Chrome Headless when you want Chrome’s URL printing from a command line, or WeasyPrint when its CLI or Python API suits your HTML pipeline. Do not choose solely on assumed speed or perfect CSS fidelity; no controlled comparison establishes either.
Check the PDF and troubleshoot common failures
Before relying on a converted file, open it and check the pages or elements that matter. The HTML-to-PDF step can succeed while the result still has an unwanted page break, missing image, or incomplete dynamic content.
| Symptom | Likely cause | What to try |
|---|---|---|
| The PDF is missing content that appears later on the webpage | The page renders content asynchronously, or the capture wait ended before that content appeared. | For Chrome Headless, adjust the wait approach or timeout for the page, then verify a representative output before automating a batch. |
| Page breaks, margins, or backgrounds look wrong | The printed layout differs from the screen layout, or a print setting is not what you expected. | Use Chrome’s preview and available print controls, save a new file, and inspect it rather than judging only from the webpage. |
| A WeasyPrint PDF lacks styles, images, or fonts | A resource path may not resolve, a remote resource may be unavailable, or a CSS property may be unsupported. | Check the resource locations and converter warnings; compare the rendered pages with the intended layout. |
| A WeasyPrint conversion cannot access a signed-in page | The default HTTP client does not support cookies or authentication. | Consider whether a custom URL fetcher fits the case, or use a workflow that can provide the necessary authenticated state. |
| A headless command does not run | The Chrome executable may not be installed under the command name chrome or may not be on the command path. |
Use the executable path for your installation and confirm that the command can launch Chrome in the environment running the job. |
| The PDF exists but differs from what a visitor sees | Print styling, delayed page content, or site-specific behavior changed the captured result. | Compare the output with the live page, check when the missing content loads, and test the selected conversion route on that page. |
Performance, reliability, and cost
The browser print dialog is a practical choice when a person can review each file. Headless capture and library-based conversion are better suited to repeatable jobs, but automation shifts the work to setup, page readiness, resource access, and output verification. A timeout can cap a Chrome Headless wait; it cannot guarantee the page has become complete by that point.

The documented routes above do not require a screenshot or PDF API key, and this article does not claim a particular conversion speed, batch capacity, or output-fidelity score. Those depend on the page and environment; test representative pages, especially those with delayed content, authentication, or complex styling. The software routes described here do not state a conversion fee, but any costs associated with your computer, hosting, or other infrastructure are separate from an API price.
Or skip the browser setup
ScreenshotNeo is a website screenshot API and MCP server. Its API requires an access key, so it is not a no-key alternative to the browser and local-tool methods above. It can return PNG, JPEG, WebP, or PDF; see the ScreenshotNeo documentation for the PDF request format. The following one-call example saves a webpage screenshot as WebP; it is an image example, not a PDF conversion command:
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://stripe.com -o shot.webpScreenshotNeo says it accepts cookie and consent banners like a visitor and removes more than 60 known consent platforms, newsletter popups, and chat widgets before capture; each of those steps can be turned off. Bot checks or CAPTCHAs, blank pages, timeouts, failed loads, and cache hits are not billed, and responses report the page verdict and billing status in headers. Its MCP server provides take_screenshot, get_page_info, and capture_pdf tools for Claude, Cursor, and other MCP clients.
The Free plan includes 1,000 screenshots a month with no card; paid plans start at $5 for 3,000, and every feature is available on every plan. See ScreenshotNeo, or sign up free for 1,000 screenshots a month with no card.
Frequently Asked Questions
Can I convert HTML to PDF without an internet connection?
A local HTML file can be converted offline if the chosen tool and all required page resources are already available locally. A webpage URL or remotely hosted images and stylesheets require network access.
Does saving a webpage as PDF create a scanned document?
No. The print workflow produces a PDF from webpage content; it is not the same as scanning a paper page into an image-based PDF.
Does Chrome’s scanned-PDF OCR privacy statement apply to webpage printing?
No. Chrome Help’s statement that OCR for scanned PDFs runs on-device without sending data to Google or third parties refers to OCR when opening scanned PDFs, not to every webpage print or PDF workflow.
