Word to PDF
Convert DOCX, DOC, or ODT documents to PDF. Server-side LibreOffice engine. Free, no signup, no watermark.
Server-side processing
Your file uploads over HTTPS, gets converted by LibreOffice, then deleted immediately. Nothing logged or stored.
Convert DOCX, DOC, or ODT documents to PDF using LibreOffice on the server. Preserves formatting, fonts, embedded images, and tables. Free, no watermark, no signup.
Convert Word to PDF is the most-searched PDF operation worldwide in 2026 — about 100 search interest points on Google Trends, far ahead of any other format conversion. Whether you're sharing a finalized contract, submitting a CV that won't reflow on the recipient's machine, or archiving a manuscript, PDF is the universal delivery format.
Pick Rack's Word to PDF tool uses [LibreOffice](https://www.libreoffice.org) headless on the server — the same engine professional document workflows have used for over a decade. Output preserves formatting (fonts, headings, paragraph styles), embedded images, tables, headers/footers, page breaks, and most styling.
Free, no signup, no watermark, no daily quota. Files up to 30MB.
Key features
- Industry-standard LibreOffice engine — Same headless conversion used by Linux servers, government agencies, and enterprise document pipelines.
- Preserves formatting — Fonts, headings, paragraph styles, embedded images, tables, headers, footers, and page breaks all carry through. Output looks like the source.
- DOCX, DOC, and ODT supported — Modern Microsoft Office (DOCX), legacy Office (DOC), and OpenDocument (ODT). LibreOffice handles all three natively.
- No watermark, no signup — Output is your converted PDF — no promotional banners, no daily limit, no "upgrade to remove watermark" nag.
- Server-side, deleted immediately — File uploads over HTTPS, gets converted, then deleted from server temp storage. No logging.
How to use
- Step 1: Upload your Word document — Drop or click to add a single .docx, .doc, or .odt file (up to 30MB).
- Step 2: Click Convert to PDF — Server processes via LibreOffice. Most files complete in 5-15 seconds.
- Step 3: Download the PDF — Output PDF downloads directly with the same base name as the input file.
When to use
- Submit professional documents (CV, cover letter, proposal) in PDF format that displays consistently regardless of the recipient's software
- Lock down a contract before sending — recipients can read but cannot easily edit
- Archive Word documents in PDF/A-friendly format for long-term storage
- Convert manuscripts for online submission systems that require PDF only
- Share academic papers where reviewers need consistent page numbering and footnote layout
- Email-friendly delivery — recipients open PDF without needing Word installed
Frequently asked questions
Will the converted PDF look exactly like the original Word document?
Very close, but not pixel-perfect 100% of the time. LibreOffice handles standard Word features (headings, paragraphs, tables, images, headers/footers) accurately. Edge cases that may shift slightly: complex SmartArt, embedded Excel charts, custom WordArt, very specific font kerning, and macro-driven content. For standard documents (95% of use cases) the conversion is indistinguishable.
Are my fonts preserved in the output PDF?
Yes, when the fonts are embedded in the source document or available on the server. Standard Microsoft fonts (Arial, Times New Roman, Calibri, Cambria) and major Linux fonts (Liberation, DejaVu) work. If your document uses an exotic font not on the server, LibreOffice substitutes the closest match — usually unnoticeable for most readers.
Can I convert .doc files (legacy Word format)?
Yes. Pick Rack accepts .docx (Office 2007+), .doc (legacy Office 97-2003), and .odt (OpenDocument). All three convert to PDF via the same LibreOffice engine.
What is the maximum file size?
30MB per file. For larger documents (long manuscripts, image-heavy reports), split into sections, convert each, then merge the resulting PDFs using Pick Rack's Merge PDF tool.
Does the PDF output include hyperlinks from the Word document?
Yes. Internal links (table of contents, cross-references) and external URLs are preserved as clickable hyperlinks in the output PDF, working correctly in Adobe Reader, Foxit, Preview, and browser PDF viewers.
Is my Word document private during conversion?
The file uploads over HTTPS to the server, gets processed in a private temp directory by LibreOffice, then the temp directory and all files are deleted immediately after the response is sent. Nothing is logged or persisted. For absolute privacy, run LibreOffice locally yourself: libreoffice --headless --convert-to pdf input.docx produces identical output.
Can I convert multiple Word files at once?
Currently the tool processes one file per conversion. For batch conversion, upload files individually. A batch interface may be added in the future.
Will tracked changes and comments appear in the PDF?
By default, accepted tracked changes appear as final text and comments are not included. If you need to preserve markup, accept or reject all changes in Word first, then convert. Comments in the Word document do not transfer to the PDF.
