ebook-converter-lib

ebook-converter-lib is a Python library and command-line tool for converting ebooks between common formats. It is a modified fork of ebook-converter by gryf, which is itself derived from the conversion components of Calibre. Licensed under GPL-3.0-or-later.

Install

python -m pip install ebook-converter-lib

Python 3.11 or newer is required. PDF conversion also requires Poppler tools (pdftohtml, pdfinfo, and pdftoppm) available on PATH.

Use as a library

from ebook_converter_lib import convert

result = convert("book.docx", "book.epub")
if not result["success"]:
    raise RuntimeError(result["message"])

convert() returns a dictionary with success and message keys. Use check_deps_str() to verify that conversion dependencies can load in an embedded Python runtime.

Options

Extra arguments use the command-line option format:

convert("book.epub", "book.mobi", "--base-font-size", "12")
  • --remove-text: one regular expression per line, every match is deleted. Escape special characters for literal text, e.g. C\+\+.
  • Unknown options, stray values and invalid regular expressions fail the conversion.

Command line

ebook-converter book.docx book.epub

Supported formats

Input: azw, azw3, docm, docx, epub, fb2, fbz, htm, html, htmlz, lrf, markdown, md, mobi, odt, opf, pdb, pdf, pobi, prc, rtf, shtm, shtml, text, textile, txt, txtz, updb, xhtm, xhtml.

Output: azw3, docx, epub, fb2, html, htmlz, lrf, mobi, oeb, txt, txtz.

The output format is chosen from the output file extension.
