How it works

Private, fast, free

No uploads, no accounts, no limits. Conversion runs entirely in your browser.

🔒 Fully private

Your ODT file is read locally by your browser. No data is sent to any server. Works offline after the page loads.

⚡ Instant conversion

Conversion runs in milliseconds using odf-kit's pure JavaScript reader. No waiting for upload or server processing.

📋 What is preserved

Headings (# through ######), paragraphs, bold, italic, strikethrough, lists (bullet and numbered, nested), tables (GFM pipe format), hyperlinks, and line breaks.

🆓 Free, always

No file size limits, no conversions per day limit, no sign-up required. Powered by open source odf-kit.
