Headings become chapters. Code blocks, lists, links and images are kept where supported. Add metadata and cover, then export in your browser.
- H1 headings become chapters you can review
- Code blocks, tables and lists preserved
- YAML frontmatter sets title, author and language
- Free Markdown conversion runs locally
How it works
02
Review structure
Chapters detected from H1 headings. Edit metadata, reorder, add a cover.
03
Download EPUB
Export an EPUB draft with TOC, metadata and cover.
Built for writers and developers.
Headings → Chapters
Every H1 heading splits a new chapter. Subheadings stay inside.
Code & Tables
Fenced code blocks, tables, blockquotes and lists are kept where EPUB supports them.
Multi-file Books
Upload a .zip of Markdown files. Natural sort order builds the chapter list.
Local by Default
Free Markdown conversion runs in your browser. Cloud Library is optional.
How chapters are detected.
Single file
Every # H1 heading splits a new chapter. The heading text becomes the chapter title in the table of contents. Subheadings (## and below) remain inside the chapter as section markers.
Multiple files / ZIP
Each .md file becomes one chapter. Files are sorted by natural order — 01-intro.md before 02-setup.md before 10-end.md — so double-digit numbers sort correctly after single-digit ones.
Metadata from YAML frontmatter.

title | Book title — overrides H1 if present |

language | BCP 47 tag — en, fr, de, etc. |
