DOCX is the file format Word has used since 2007 — a ZIP archive of XML files describing the document’s text, styles, images, and relationships. The structure is open and well-documented, which is why there are dozens of DOCX-to-PDF converters in the world. The quality of those converters varies widely: the best ones (Word itself, Adobe Acrobat, LibreOffice) preserve the layout exactly because they use the same rendering engine that produced the DOCX. Browser-based converters are at the other end of the spectrum — they extract the text and structure, then re-render with a different engine, which means the output is a faithful reading of the source but may not match the source’s exact page layout.
The non-obvious thing about DOCX-to-PDF is what gets lost. The DOCX format can store custom fonts, complex tables with merged cells, footnotes, comments, tracked changes, text boxes, headers and footers, and a long list of formatting features that browser-based converters do not support. The tool here uses mammoth.js, which is one of the better open-source DOCX-to-HTML converters, then lays out the HTML with a PDF renderer. The output preserves text, headings, lists, basic tables, and embedded images. It does not preserve custom fonts, complex tables, comments, or tracked changes. For a document that uses those features, the right pick is Word’s native Save as PDF.
For a final hand-off: if the goal is a faithful rendering of a Word document, use Word’s File > Save as PDF on a desktop with Office installed. If the goal is a quick conversion of a simple document (a text-heavy report, a meeting agenda, a draft contract), the browser tool gives a readable output in seconds. If the goal is a long-term archive, the DOCX itself is a better archival format than the PDF — it is searchable, editable, and version-control-friendly. Convert to PDF only when the destination requires a fixed-layout, non-editable format.
How to use
Drop a .docx file
Drag a Word document into the drop zone, or click to browse. The .docx format is supported; the older .doc binary format is not — re-save from Word as .docx first if the source is legacy.
Wait for the conversion
The tool extracts the document's text and styles using mammoth.js, lays it out with a headless renderer, and produces a PDF. Layout fidelity matches what mammoth.js supports — text, headings, lists, and basic tables.
Download the PDF
The output is a single PDF named after the source file. Page count and file size are shown above the download button so you can verify the conversion before saving.
Frequently asked
Will images and tables be preserved?
Images embedded in the DOCX are included in the PDF. Tables are converted to a basic grid — complex tables with merged cells, nested tables, or custom border styles may render with simplified formatting.
What about fonts and styling?
The PDF uses the standard PDF font set (Helvetica for body, Times for headings, Courier for code) so it renders identically on every device. Custom fonts from the DOCX are not embedded — the visual emphasis is preserved through font weight and size, not the exact typeface.
Are comments and tracked changes preserved?
Comments and tracked changes are not visible in the PDF output. The document is converted in its accepted-changes state — if you need to preserve revisions, accept or reject them in Word first, then convert.
Can I convert password-protected DOCX files?
No — the tool does not accept password-protected files. Remove the password in Word (File > Info > Protect Document > Encrypt with Password) before converting, or use a desktop tool that supports encrypted DOCX.
Will the PDF be searchable?
Yes — the PDF has a text layer, so the output is searchable in any PDF viewer (Adobe Acrobat, Preview, Chrome). The text matches the source DOCX's content, not the rendered glyphs.
Limitations
- No advanced Word featuresHeaders and footers, footnotes, endnotes, table of contents, and text boxes are not preserved. The output is a flat rendering of the body text and basic structure. For complex Word documents, use Word's native Save as PDF.
- No custom fontsCustom fonts from the DOCX are not embedded in the PDF. The output uses the standard PDF font set, so a DOCX in Calibri renders in Helvetica, a DOCX in Times New Roman renders in Times. Visual emphasis is preserved through weight and size.
- Layout may shiftWord's layout engine and the PDF renderer use different page-break algorithms. A page break in the source DOCX may land at a different position in the PDF, especially for documents with mixed font sizes, images, and tables.
Platform notes
- macOS
- macOS Pages can open .docx files and export to PDF with better layout fidelity than this tool. The browser tool is the right pick for quick conversions where opening Pages is not worth the setup time, or for content pasted from chat or email.
- Windows
- Microsoft Word's File > Save as PDF is the highest-fidelity conversion available. The browser tool is the right pick for quick conversions, for content that came from chat or email, or for cases where installing Office is not an option.
- Linux
- LibreOffice Writer opens .docx files and exports to PDF with reasonable layout fidelity. The browser tool is the right pick for content pasted from a chat, an email, or a documentation page where opening LibreOffice is not worth the setup time.
- iOS
- iOS Pages opens .docx files and exports to PDF. The browser tool is the right pick for content delivered via email, Messages, or AirDrop where the file is already on the device and opening Pages is not necessary.
- Android
- Google Docs opens .docx files and exports to PDF. The browser tool is the right pick for content delivered via email, Drive, or a chat app where the file is already on the device and opening Google Docs is not necessary.
