How to convert an EPUB ebook to Markdown
- Choose an EPUB ebookDrop or select one EPUB 2 or EPUB 3 file. There is no fixed file-size cutoff; very large books depend on the memory available in your browser.
- Review chapters and illustrationsCheck the detected headings, paragraph breaks and images. Dense chapter indexes become readable lists, and repeated image-only chapter ornaments are removed.
- Export your edited resultCopy the Markdown, download an MD file, or download a ZIP with the deduplicated image assets and their relative paths.
What LensUp keeps and cleans
LensUp keeps spine order, headings, paragraph breaks, lists, simple tables and supported illustrations. Dense inline chapter indexes are split into readable links; high-frequency image-only ornaments are removed.
The preview never loads remote images. Review publisher-specific notes, complex layouts and unusual CSS before using the result.
