Convert CBR to EPUB

CBR files are RAR archives of page images — a format most converters and e-readers refuse to touch. Tanko extracts the RAR right in your browser (old RAR4 and modern RAR5 alike), optimizes every page for your device, and packages a fixed-layout EPUB that Kindle, Kobo, and every reading app understands.

Nothing is uploaded — the RAR engine runs client-side, so there's no size limit, no queue, and your files stay on your machine.

Frequently asked questions

My file says .cbr but won't open in other tools — will it work here?
Probably. Many "CBR" files are actually mislabeled ZIP archives (and vice versa). Tanko detects the real format from the file's bytes, not its extension, so mislabeled archives convert fine.
Do I need WinRAR or any software installed?
No — the RAR extraction engine runs inside your browser. Drop the file, download the EPUB.
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.
