How it works
Unlike other converters, your document never leaves your computer.
Your DOCX file is read and converted locally by your browser. No data is sent to any server. Works offline after the page loads.
Conversion runs in milliseconds using odf-kit's pure JavaScript library. No waiting for uploads or server processing.
Headings, paragraphs, bold, italic, underline, strikethrough, font sizes, colors, lists, tables, hyperlinks, bookmarks, images (with actual dimensions), page layout, and tracked changes.
No file size limits, no conversions per day, no sign-up required. Powered by open source odf-kit.
odf-kit/docx is a free, open source JavaScript package built into odf-kit that converts DOCX to ODT with no server dependencies. Works in Node.js 22+ and browsers. No LibreOffice, no cloud APIs, no extra install.
