Turn .epub books into structured Markdown — chapters as headings, text flowing cleanly — for quoting, note-taking, and building searchable personal archives. Entirely on your Mac.
How to convert an EPUB
Drop the .epub file into Milldown.DRM-free EPUBs only — purchased books with DRM can't be read by any converter.
The book's chapters convert in order, with headings preserved.
Save as one Markdown file, or split it.Refine → Export Chunks splits by chapter headings into ~1–2k-token pieces — ideal for feeding a book to an AI a piece at a time.
What people use it for
Reading notes — pull chapters into Obsidian where quotes link to your own thinking.
Study — ask an AI questions about a chapter by pasting exactly that chapter.
Personal archives — public-domain and DRM-free books, in a format that outlives every e-reader.
Notes
Footnotes convert inline where the EPUB structure allows. Embedded images aren't carried into the text. For public-domain books, Project Gutenberg EPUBs convert beautifully.
