How to convert CBZ to EPUB
- Add your .CBZ file - drop it in the box above or click to browse.
- Convert it to .EPUB in a few seconds.
- Download your new .EPUB file.
What to expect
- The output is an image-only EPUB - pages are JPEG or PNG images, not selectable text; there is no OCR layer.
- Calibre passes the original images through without re-encoding by default, so image quality and file size stay close to the source
.cbz. - Comic metadata stored in
ComicInfo.xmlinside the CBZ may not transfer to EPUB fields; check and edit metadata in Calibre after converting.
Frequently asked questions
Does the converted EPUB work on a Kobo or Apple Books?
Yes - both handle fixed-layout image EPUBs well. Pages display one per screen; zoom and pan depend on the device or app.
Will I lose image quality during conversion?
No - Calibre passes the original page images through without re-encoding by default, so quality is fully preserved.
Can I convert CBZ to EPUB on a phone or tablet?
No convenient mobile app handles this conversion reliably. Use Calibre on a desktop first, then transfer the
.epub to your reader.What if the EPUB shows pages in the wrong order?
The source CBZ may use non-zero-padded filenames (1.jpg, 10.jpg, 2.jpg instead of 001, 002, 010); rename the image files to zero-padded numbers before converting to fix the sort order.
