Turn a CBZ chapter or volume you own into a Kindle-ready EPUB — free, in your browser.
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 outright, 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's e-ink optimization engine processes each page and packages a fixed-layout EPUB you can email to your Kindle's Send-to-Kindle address or copy over USB. No account, no watermark, and the file is yours to keep.

No. Kindle devices and Amazon's Send-to-Kindle service do not accept CBZ or CBR files. Send-to-Kindle's supported formats are EPUB, PDF, and a few document formats — so a CBZ has to be converted to EPUB before it can reach your Kindle.
Email it to your Kindle's Send-to-Kindle address (found under Amazon > Manage Your Content and Devices > Devices), after whitelisting your own sending address in Amazon's Personal Document Settings. Or connect the Kindle via USB and copy the EPUB into its Documents folder.
The free tool accepts files up to 200 MB and allows 3 conversions per day. A MangaSendr account removes the daily limit and adds direct email delivery to your Kindle, sized for your exact device model.
