How big a file can I convert?

50MB per upload, which fits the vast majority of Word files. A 100-page report with embedded images typically lands under 30MB. If your file is larger, the most common cause is uncompressed high-res images — compress them inside Word (File > Compress Pictures, set to Email or Document quality) and try again, or split the document into halves and merge the resulting PDFs with the merge tool.

My document has a watermark — will it survive?

Yes, Word watermarks (the gray DRAFT or CONFIDENTIAL text behind your content, set via Design > Watermark) render correctly in the PDF output. Image watermarks (a logo overlay) also work. If you want to remove a watermark before converting, do that in Word first (Design > Watermark > Remove Watermark) — the conversion preserves whatever is in the source document.

What about comments and track changes?

By default, the conversion includes comments and tracked changes if they are in the source document, formatted similarly to how Word's print preview shows them (margin balloons for comments, colored insertions and strikethroughs for changes). If you want a clean PDF without the markup, accept all changes and delete all comments in Word first, then re-upload. Or use Word's File > Export > Create PDF with the markup option turned off.

Will mathematical equations render correctly?

Yes for equations entered via Word's Equation Editor (Insert > Equation) — they carry through as rendered math, not as images. For equations imported from MathType or other third-party tools, the rendering can be uneven; complex multi-line equations sometimes lose alignment. For mission-critical math typography, LaTeX is the gold standard, and there are dedicated LaTeX-to-PDF tools that handle it better than a Word route.

Why does the PDF look slightly different from the Word document?

Usually because LibreOffice's rendering is not pixel-identical to Word's — they are different rendering engines. Common visible differences: slightly different spacing between certain characters, minor differences in how lists are indented, occasional shifts in how images wrap around text. For most business documents the differences are invisible to a casual reader. If absolute fidelity matters, use Word's own Save-as-PDF on a desktop install where available.

Will the PDF be searchable and accessible?

Yes. The output PDF has a real text layer (not rasterized), so search and text selection work. Screen readers can read the content correctly. The document structure (headings, paragraphs, lists) carries through as tagged PDF structure, which is important for accessibility compliance. For full WCAG-compliant tagged PDFs, you may need to do additional tagging in Acrobat Pro after conversion, but the baseline accessibility is reasonable.

Can I add a digital signature to the PDF?

Not from this tool directly — sign the PDF afterward with a dedicated signing tool (Adobe Acrobat, DocuSign, HelloSign, or a desktop tool like LibreOffice Writer's digital signature feature). The conversion path here is content-fidelity only; cryptographic operations like signing are a different concern. Once the PDF is produced, signing it does not invalidate the conversion fidelity.

Do bullet styles and numbered lists carry through correctly?

Yes for standard Word bullet and numbering styles (round bullets, dashes, decimals, lowercase letters). Custom bullet characters or unusual list styles may render as the closest standard equivalent. Nested lists work; the indentation level is preserved. Some highly custom multi-level list styles defined in Word's List Library may need touch-up after conversion, but plain a/b/c or 1/2/3 lists come through cleanly.

What is the difference between this and printing to PDF from Word?

Word's built-in Save-as-PDF (File > Save As > PDF) uses Microsoft's own rendering engine and is the gold standard for fidelity if you have a desktop Word install. This tool uses LibreOffice's open-source equivalent, which is very close but not identical for unusual layouts. The main reason to use this tool is when you do not have Word installed (Chromebook, Linux, iPad, borrowed machine), or when you want a quick conversion without launching the Word app.

Converting Word to PDF is the boring-but-necessary final step before sending a document to anyone who is not you. PDF locks the layout — your recipient sees exactly what you sent, regardless of what version of Word they have, what fonts they have installed, or what zoom level they prefer. This tool uploads your .docx over HTTPS to a server in Germany (Hetzner data center) running LibreOffice, which renders the document and exports as PDF. Fonts get embedded, images stay sharp, tables and headers and footers all carry through. Hyperlinks stay clickable in the output. The file is deleted from the server within 10 minutes. Most documents finish in under 5 seconds. The output is comparable to what you would get from Word's own Save-as-PDF feature on a desktop install. The how-to and FAQ below cover what formats are supported (more than just .docx), how to handle missing fonts, and the round-trip workflow with PDF-to-Word.

How to word to pdf converter online free

Upload your .docx

Drag and drop or click to browse. The tool accepts modern Word files (Word 2007 and later) as well as .odt, .rtf, and a few other word-processor formats.
Wait for the conversion

Server-side LibreOffice renders the document with fonts embedded, images placed, and pagination matching what Word would produce.
Download the PDF

Output is a standard PDF that opens in any reader. Fonts are embedded so the recipient does not need them installed on their machine.
Verify before sending

Open the PDF and skim it. 99% of conversions are perfect; the 1% issue is usually a missing font that LibreOffice substituted — easy to spot and easy to fix by embedding the font in the source Word file.

Features

Formatting kept exactly

Fonts get embedded into the PDF so the recipient sees the exact font you used, even if they do not have it installed. Images keep their original resolution (no compression during the conversion). Tables render with their borders and shading intact. Headers, footers, page numbers, footnotes all carry through. Margins are respected, page breaks are honored — the output is what Word would produce with Save-as-PDF on a desktop install. The fidelity is high for typical business and academic documents.

Hyperlinks stay clickable

External URLs in your Word doc become clickable links in the PDF. Internal links (cross-references, links to bookmarks within the doc, table-of-contents entries with page numbers) also work. Same for footnote markers, any LinkedIn or email links in your CV, and embedded mailto: addresses. The PDF is a working document, not a flat snapshot. This matters for CVs (where recruiters click LinkedIn links) and reports (where readers navigate by TOC).

No PowerPoint or Word needed locally

Useful when you are on a Chromebook, Linux machine, iPad, or someone else's computer where Word is not available. The conversion runs server-side using LibreOffice, so your local machine just needs a browser. This is the main use case the tool gets — Mac and Windows users mostly have Word and use its built-in export, but the rest of the world (Chromebook users, Linux users, mobile-only users, people on borrowed machines) needs an option.

Quick, no queue

Most documents (under 50 pages) finish in 2-4 seconds. No queue, no rate limit, no daily cap. The server runs LibreOffice in a Docker container and recycles workers between requests. For huge files (200+ pages with lots of embedded media) the conversion takes 15-30 seconds, but you are unlikely to have many of those. The auto-delete after 10 minutes means we are not building up a stash of customer documents on the server.

Frequently asked questions

Which Word formats does it support?

Modern .docx files (Word 2007 and later) work natively. Older .doc files (Word 97-2003) also work because LibreOffice can read them. The tool also accepts .odt (OpenOffice/LibreOffice native format), .rtf (Rich Text Format used by many older tools), and a handful of less common word-processor formats. If your file format is rejected, open it in Word or LibreOffice first and save as .docx, then come back here.

Will my fonts be embedded in the PDF?

Yes, LibreOffice embeds fonts in the output PDF by default. So the recipient sees the exact typeface you used, regardless of what fonts they have installed. The exception is very rare custom or licensed fonts that explicitly forbid embedding via their license metadata — those get substituted with a similar typeface during conversion and the PDF flags the substitution in its metadata. For mission-critical typography, embed fonts in the .docx before uploading (File > Options > Save > Embed fonts in the file).

What about my custom Word styles?

Standard Word styles (Heading 1, Heading 2, Normal, lists, quote blocks) render correctly. Custom styles you defined are also respected because LibreOffice reads the style definitions from the docx XML. Highly unusual style combinations (e.g. multi-column layouts with custom borders, complex tab-stop rulers, drop caps) may render slightly differently — typically a kerning or spacing difference, not a layout breakage. Test once before sending if your document uses unusual styling.

Is the conversion reversible?

Yes — run the output PDF through the PDF-to-Word tool (also on this site) to get a Word doc back. The round trip is not lossless (some formatting will drift, especially on complex layouts), so for active documents you should keep the original Word file as the source of truth and only generate PDFs when you need to share. For one-off rescue operations (you only have the PDF and need the Word back), the round trip is usable.

Where does my file go?

Uploaded over HTTPS to our server in Germany (Hetzner data center). Processed in a temp directory by LibreOffice running in a Docker container, the output PDF is sent back to your browser, and both files are deleted from the server within 10 minutes by a scheduled janitor process. No file contents are logged, no copies are kept, and no third-party analytics are involved in the conversion path. The same flow applies to all server-side tools on the site.
