DOCX to PDF
Turn modern .docx files into PDFs locally. Free, no upload — pick A4 or Letter and review the result.
DOCX in, PDF out
DOCX has been Word's default format since 2007, and it is really a ZIP archive of XML — which is why a browser can parse it without Word installed. The tool above reads your .docx with mammoth, renders it to PDF locally, and hands you the download. Twenty files at a time, A4 or Letter, no account, no upload. The general converter page is Word to PDF converter.
Legacy .doc files
The old .doc binary format is a different beast and is not supported here. If your file ends in .doc, open it in Word (or Google Docs, or LibreOffice) and use Save As / Download to convert it to .docx first — it takes ten seconds and the result works with this tool. Templates (.dotx) and macro-enabled documents (.docm) are also outside the supported scope.
Page size: A4 or Letter
The choice affects page dimensions only. Pick A4 for Europe, Asia, Africa, South America and Oceania; pick Letter for the United States, Canada and Mexico. If you are unsure, match the page size of the original document — mismatched sizes are the most common cause of surprising page breaks. Either way, skim the downloaded PDF: pagination is best-effort and can differ from Word, especially in documents with many floating images or complex tables.
Check before you share
Make the review step a habit: open each PDF, scroll through it, confirm headings, lists and tables landed where expected, and confirm nothing confidential was meant to stay out. Pay special attention to page breaks — a heading stranded at the bottom of a page or a table split awkwardly is the most common cosmetic issue, and it takes seconds to spot. Only then attach or upload it. At no point did your document leave your device.
Frequently asked questions
What is the difference between DOCX and DOC?
DOCX is the modern XML-based Word format (since Word 2007); DOC is the legacy binary format. This tool supports .docx only — resave old .doc files as .docx in Word first.
Are password-protected DOCX files supported?
No. Encrypted documents are rejected, as are files with more than 1,000 ZIP entries or over 80 MB of declared expanded size (a zip-bomb precaution).
A4 or Letter — which should I choose?
A4 is standard almost everywhere; Letter is standard in the US, Canada and Mexico. Match whatever your recipient expects.
Will images appear in the PDF?
No. Embedded images are skipped; the PDF contains text and structure. Complex formatting may also differ — always review before sharing.
Is the file uploaded?
No. Parsing and rendering happen entirely in your browser.
