How to use it
- Add your files. Drop CBZ files on the page or use Choose files. Folders and ZIPs work too.
- Check that EPUB is selected. EPUB is already chosen on this page.
- Adjust options if you need to. Quality, size and other settings appear when the format has them.
- Convert and download. Press Convert; with several files, “Download all” gives you one ZIP.
What happens to your file
The comic’s page pictures are read from the archive in file-name order and put into the EPUB unchanged, one picture per page; JPG and PNG pages are not re-compressed.
About CBZ and EPUB
CBZ: CBZ is a comic book: the page pictures in a ZIP archive.
EPUB: EPUB is the standard ebook format, read by Apple Books, Google Play Books, Kobo and most e-readers.
Questions
Is my CBZ file uploaded?
No. The conversion runs inside this browser tab, and the EPUB is created on your device. Nothing is sent to a server.
Is anything lost when converting CBZ?
Pages are kept as the original pictures, in file-name order.
Anything to know about EPUB?
Text, headings, pictures and chapters are kept; the ebook’s own fonts and page styling are not. DRM-protected ebooks cannot be opened.
Can I convert several CBZ files at once?
Yes. Drop as many as you like, a folder or a ZIP; “Download all” saves every EPUB in one ZIP.
