How to convert Word to PDF
- Drop a Word document (.docx) onto the box above, or tap it to choose a file from your computer or phone.
- Check the preview. Headings, paragraphs, bold and italic text, lists, tables, links, footnotes and images are kept.
- Keep the document's own page setup, or pick the paper size (A4, Letter, Legal or A5), orientation and margins.
- Press Download PDF to get the PDF file directly. Or press Print / save with the browser and choose Save as PDF as the printer in the dialog that opens.
Private conversion, with honest limits
Most "Word to PDF" sites upload your document to their servers, which is a problem for contracts, CVs, medical letters and coursework. Here the .docx file is unpacked and converted inside your browser by the open-source Mammoth library, and the PDF is written in the browser too, with the fonts embedded. The result has selectable, searchable text and working links, and the file never leaves your device.
Because the document is re-laid out rather than copied page by page, the PDF follows the content and structure of your file but not every pixel of Word's layout. Page breaks, section breaks, page size and margins, headers, footers, page numbers and columns are kept, but lines can wrap differently because fonts are substituted, so later pages may not end at the same line. Text boxes, colours and exotic fonts are simplified. For CVs, essays, reports, letters and notes this works well. If the exact layout matters, for example a designed flyer, use Word's own File → Save As → PDF, LibreOffice (free), or Google Docs → Download → PDF.
Example: what the PDF keeps
A 3-page Word document became a 3-page PDF with every word of the document in it (100%): the header, the page numbers, a footnote, a text box, a two-column section, a table and an image. A one-page letter stayed one page. Neither PDF had a blank page, and the text in both can be selected and searched. Each conversion took under half a second in Chrome on a laptop.

Is my Word document uploaded?
No. The conversion runs entirely in your browser, and the converter code comes from this site.
Can I convert old .doc files?
Not directly. Open the .doc in Word, LibreOffice or Google Docs and save it as .docx first.
Why does the PDF look slightly different from Word?
The document is converted to a web layout before printing, so fonts, spacing and page breaks can differ. Text, headings, tables, lists and images are kept.
Does it work on iPhone and Android?
Yes. Choose the file, then use Save as PDF; your phone's print or share sheet lets you save the PDF to Files or Drive.
Will the PDF keep my headers, footnotes and images?
Yes. Headers, page numbers, footnotes, tables, lists and images are carried into the PDF, and the text stays selectable. Fonts that are not on your device are replaced with similar ones, so lines can wrap a little differently from Word.
