DOCX Converter
Convert Word (.docx) to PDF with LibreOffice — up to 500 MB. Files are deleted after about 15 minutes.Convert DOCX to PDF online
Upload a .docx (Office Open XML, ECMA-376 / ISO/IEC 29500), convert it with LibreOffice headless on our servers, then download a PDF. Cap is 500 MB per file; input and output are deleted automatically after about 15 minutes. No account required.
Will formatting stay the same?
Usually yes for text, headings, and simple tables. Complex layouts, uncommon fonts, SmartArt, and tracked changes can shift because LibreOffice re-lays out the document — the same class of differences you see opening a DOCX in another word processor.
Is my document kept forever?
No. We store the upload and the PDF only to finish the job. Retention is about 15 minutes, downloads need a private job token (not a public share link), and the size limit is 500 MB.
Is this free?
Yes for normal use. There is no signup wall; abuse controls may apply if someone floods the queue.
DOCX vs PDF — which should I keep?
Keep DOCX when you still need to edit. Export PDF when you need a fixed, printable, widely accepted exchange format for forms, contracts, and email attachments.
