Markdown to EPUB Converter

Summary

This tool takes any Markdown text and assembles a valid EPUB 3 ebook in your browser using marked.js (MD to HTML rendering) and JSZip (ZIP packaging). Enter a title and author, paste your Markdown, then click Convert and Download. The tool builds a standards-compliant EPUB 3 container with an OPF package, navigation document, and XHTML content chapter — all without uploading anything to a server.

How it works

1. Paste your Markdown text into the editor, or load a .md file from your device.
2. Enter a book title and author name in the metadata fields.
3. Click "Convert & Download" — marked.js renders the Markdown to HTML.
4. JSZip wraps the HTML in a valid EPUB 3 container (mimetype, container.xml, OPF, nav, content).
5. The .epub file downloads immediately, ready for any e-reader or Calibre.

Use cases

• Package Markdown meeting notes or reports as portable ebooks.
