Convert DOCX to PDF in Your Browser
Turn a Word .docx file into a .pdf — without uploading it anywhere. The whole conversion happens locally in your browser.
How it works
- Click Open your DOCX to launch the editor in your browser.
- Pick the .docx file from your device, or drag and drop it onto the page.
- Choose Download as / Save as and pick PDF.
- The PDF is generated on your device and downloaded — nothing is uploaded.
Almost every "DOCX to PDF" service on the web works the same way: you hand them your document, their server converts it, and you download the result. That means a contract, a CV or a medical letter sits on someone else's machine, however briefly. This one never sends it: the file is read straight from disk into your browser tab, converted there, and written back out.
The conversion is done by OnlyOffice's x2t engine compiled to WebAssembly — the same engine that renders the document on screen, so what you see in the editor is what lands in the PDF. Fonts, tables, images, headers and footers, page breaks and numbering all carry over. Because it runs in your tab there is no upload queue, no server-imposed file size cap, and no wait for someone else's job runner.
This is the practical option when the document is not yours to share: an offer letter before it is signed, a report under embargo, anything with personal data in it. It is also the option that keeps working on a plane or behind a corporate firewall, because once the page has loaded it is an installable app that runs with no network at all.
Frequently asked questions
How do I convert a DOCX to PDF here?
Open the DOCX in the editor, then use Download as / Save as and choose PDF. The conversion runs in your browser.
Is my document uploaded to convert it?
No. The file is opened and converted entirely inside your browser tab, so it never leaves your device.
Do I need Microsoft Word or an account?
Neither. No Word, no 365 subscription, no sign-up.
Is the formatting preserved in the PDF?
Yes. The same OnlyOffice engine that renders the document produces the PDF, so fonts, tables, images and page layout carry over.
Is there a file size limit?
No fixed limit. The practical ceiling is your device's memory, because the whole document is converted locally.
Does it work with old .doc files?
Yes. Both the modern .docx and the older binary .doc open with the same engine and can be exported to PDF.
Can I convert a PDF back to Word?
No. This exports to PDF; it does not rewrite an existing PDF's text back into a Word document. You can open and annotate a PDF though — see Open PDF.
Does the conversion work offline?
Yes. Once loaded it is an installable PWA, so it keeps converting with no internet connection.
