Ebook converter
Direct conversion between EPUB, MOBI, AZW3, FB2, PDF, DOCX, TXT and more needs Calibre's ebook-convert installed on the server — it is not currently available on this server. Below that, a dependency-free fallback handles EPUB and FB2 to/from plain text on any host.
Convert between any supported formats (needs Calibre)
EPUB → plain text
Plain text → EPUB
FB2 ↔ plain text
What is Ebook converter?
Ebook formats are numerous and mostly incompatible — EPUB (most readers), MOBI/AZW3 (Kindle), FB2 (popular in Eastern Europe) — converting between them normally requires desktop software like Calibre.
How to use it
Full format-to-format conversion uses Calibre's ebook-convert where it's installed on the server. A dependency-free fallback (real ZIP/XML parsing, no external tools) handles EPUB and FB2 to/from plain text on any host.
Example
A plain text file with chapter headings converts into a genuinely valid, readable .epub file.
