Read CBZ files on your Kindle
Kindles can't open CBZ files — but Amazon's Send to Kindle accepts EPUB and converts it perfectly on their side. Tanko turns your CBZ into a Kindle-tuned EPUB: pages sized for your exact Kindle model's screen, grayscale-optimized for e-ink, with correct reading order and cover.
Convert below, then send the EPUB through Send to Kindle (web, app, or email) and it appears in your library like any purchased book.
Frequently asked questions
- Why EPUB and not MOBI or AZW3?
- Amazon retired MOBI for Send to Kindle; EPUB is the format they now recommend. Their servers convert it to the Kindle's native format automatically — tanko's output validates clean against Amazon's own conversion toolchain.
- Which Kindle models are supported?
- All current models have profiles: basic Kindle, Paperwhite, Oasis, Scribe, and Colorsoft — each with its exact panel resolution so pages render pixel-sharp.
- Do my files get uploaded anywhere?
- No. Conversion runs entirely in your browser — the file never leaves your device. That's also why there are no size limits or queues.
- Is this really free?
- Yes. Single-file conversion with every device profile and every option is free, with no sign-up and no watermarks.
