Convert Word to PDF without uploading your document

Most online Word-to-PDF converters work by uploading your file to a server, converting it there, and sending a PDF back. That is fine for a shopping list and a genuine problem for an employment contract, a signed agreement, a medical letter, or a CV containing your home address and phone number. This converter takes a different approach: your .docx file is read directly by your browser using mammoth.js, an open-source library, and turned into a PDF by your browser's own print engine. The document never travels over the network. You can watch this in a browser's network panel, or disconnect from the internet after the page loads and convert anyway.

What is preserved, and what is not

Being straight about this matters more than a marketing claim. The converter maps the structure of your Word document onto the PDF: headings, bold and italic text, bulleted and numbered lists, tables, hyperlinks and embedded images all come through. What it does not do is reproduce Word's exact pagination and font metrics — where Word breaks a page, how it kerns a particular typeface, or how it lays out a complex multi-column design.

The reason is structural rather than a shortcoming to be patched: matching Word pixel-for-pixel requires a full layout engine, which is why every converter that promises it runs LibreOffice on a server — and therefore needs your file. Choosing to keep the file on your device means accepting semantic fidelity instead of pixel fidelity. The preview shows exactly what you will get, so you can check before downloading rather than discovering it afterwards.

Only .docx, not .doc

The modern .docx format is a ZIP archive of XML, which a browser can read. The older .doc format is a binary format from the 1990s that cannot practically be parsed client-side. If you have a .doc file, open it in Word, Google Docs or LibreOffice and use Save as or Download as to produce a .docx first — that conversion is free in all three.

How the PDF is produced

After conversion the document is rendered as a page preview, and Download PDF opens your browser's print dialog with the page size and margins you picked. Choose Save as PDF as the destination. This uses the same PDF engine your browser uses everywhere else, which means the text stays selectable and searchable in the result rather than being flattened into an image.

Frequently Asked Questions

Yes, completely free. There is no signup, no usage limit, no watermark on the PDF, and no payment. The tool runs in your browser.
No. Your document is read directly in your browser and converted there. The file never leaves your device, which makes the tool suitable for contracts, CVs, and confidential documents. Only the converter library itself is downloaded from a CDN, never your file.
No, only .docx. The older .doc format is a binary format that cannot be read in a browser. Open the file in Word, Google Docs, or LibreOffice and save it as .docx first, then convert it here.
It preserves your content and structure - headings, bold and italic text, lists, tables, links, and images. It does not reproduce Word's exact page breaks or font metrics, because that requires a layout engine running on a server. Any browser-based converter promising pixel-perfect output is uploading your file. Check the preview before downloading.
20 MB. Because conversion happens on your own device, speed depends on your computer rather than on a server queue. Most documents convert in a second or two.
