Document Converter

Convert DOCX, ODT, RTF, Markdown, HTML, TXT and EPUB to Word, PDF, Markdown, HTML, TXT, RTF or EPUB.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Document Converter works

Every document is turned into clean, semantic HTML on your device (mammoth for Word, rtf.js for RTF, marked for Markdown), then written to the target with docx, turndown or the built-in PDF renderer.

Input: DOCX, ODT, RTF, MD, HTML, TXT, EPUB, MOBI, FB2. Output: DOCX, PDF, MD, HTML, TXT, RTF, EPUB.

How to use Document Converter

1. Drop a document or paste Markdown.
2. Check the preview.
3. Pick the output format and convert.

Tips

• Conversions run entirely in your tab, so very large files depend on your device’s memory.
• For best fidelity, start from the original digital file rather than a scan.

Document Converter FAQ

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
