kepubify (v3)
Kepubify converts EPUBs to KEPUBs. Kepubify also includes two standalone utilities: covergen (which pre-generates cover images), and seriesmeta (which updates the database with Calibre or EPUB3 series metadata).
___



Features:

• Batch conversion
• Standalone and cross platform
• Works from the command line or by dragging and dropping on Windows
• Fast (15x faster than converting in Calibre)
• Add custom CSS
• Smarten punctuation
• Can optionally pre-convert books for use in Calibre
• Complete control over output structure (see here for detailed examples)
• Almost identical output compared to original Kobo KEPUBs
• Standalone tool to pre-generate cover images (including aspect ratio changes, grayscale, and color inversion) (you can use this without kepubify)
• Standalone tool to update the database with Calibre or EPUB3 series metadata (you can use this without kepubify)

Usage (Windows) (drag and drop):

1. Download kepubify from the releases page.
2. Drag your EPUB files on to the EXE you downloaded in Windows Explorer to convert them.
3. Optionally, to use covergen or seriesmeta, download the binary and run it.

Usage (Windows):
