CBZ to EPUB Converter
Turn a CBZ chapter or volume you own into a Kindle-ready EPUB, free in your browser.
Free, 3 conversions a day without an account. CBZ, ZIP or image files up to 200 MB. Pages come out at 1072 x 1448 and turn right to left.
If a conversion goes wrong, tell us on Discord.
CBZ is the standard container for digital manga and comics: a ZIP archive of page images with a .cbz extension. It opens fine in desktop comic readers, but Kindles don't support it. Amazon's Send to Kindle service rejects CBZ attachments, and copying one over USB gets you nothing. To read a CBZ on a Kindle, it has to become an EPUB first.
This tool does that conversion in your browser. Upload a CBZ (up to 200 MB) and MangaSendr trims the plain white borders, fits each page to 1072 x 1448, a standard 6-inch Kindle size, and packages a fixed-layout EPUB that turns right to left. Send it to your Kindle with Amazon's Send to Kindle, by email, app or website. There's no account and no watermark, and the file is yours to keep.
With a free account, pages are sized for your Kindle model and sent straight to it. You don't need a card, and there's nothing to install.
Questions
Does Kindle support CBZ files?
No. Kindle devices and Amazon's Send to Kindle service do not accept CBZ or CBR files. Send to Kindle takes EPUB, PDF and a few document formats, so a CBZ has to be converted to EPUB before it can reach your Kindle.
How do I get the converted EPUB onto my Kindle?
Send it with Amazon's Send to Kindle. You can email it to your Kindle's Send to Kindle address (in your Amazon account under Manage Your Content and Devices, then Devices) from an address on your approved list in Personal Document Settings, drop it into the Send to Kindle app, or upload it on Amazon's Send to Kindle website. Don't copy the EPUB over USB: Kindles can't open EPUB files copied that way.
Is there a size or usage limit?
The free tool accepts files up to 200 MB and allows 3 conversions a day, and its pages are always 1072 x 1448. With a MangaSendr account, files are sized for your exact Kindle model and emailed straight to it. Your first volume is free.
