About Sigil
Sigil edits EPUB 2 and EPUB 3 books directly, letting you work on the underlying files while checking the rendered result. It suits authors and publishers who need to clean up converted books, adjust metadata and tables of contents, or inspect an existing EPUB.
Functionality can be extended with plugins from the community index. Releases include separate macOS builds for Apple silicon and Intel Macs, and questions are handled on the MobileRead forums rather than the issue tracker.
