Sigil Alternative for EPUB Editing
Sigil is a free open-source EPUB editor for deep HTML/CSS editing. But for common tasks like merging, splitting, or fixing metadata, you don't need a full editor.
Quick Tasks Without Sigil
- Merge EPUBs — Combine books in seconds
- Split by chapters — No manual HTML editing
- Fix metadata — Edit title/author visually
- Validate EPUB — Check for errors instantly
- Compress — Reduce file size automatically
Sigil is still the best choice for advanced EPUB code editing (modifying HTML, CSS, JavaScript inside the ebook). For everything else, Epublys is faster.
