CBR is a comic archive that usually uses RAR compression instead of ZIP. The contents are the same page images as a CBZ, just packed with a different compressor. Kindles can't open CBR files, and neither can most browser tools, because RAR extraction isn't freely licensed the way ZIP is.
The free converter below accepts CBZ and ZIP. So the quickest path for a CBR is a quick repackage: extract it with a free tool (7-Zip on Windows, Keka or The Unarchiver on macOS), compress the extracted images back into a ZIP, and upload that here. You don't need to rename it. A MangaSendr account works the same way: it reads CBR files that are really ZIP archives, but a RAR-based CBR has to be repackaged first there too.
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
Can I upload a .cbr file straight to this tool?
No. The free browser tool accepts CBZ, ZIP, and image files. Extract the CBR with a free archiver (7-Zip, Keka, The Unarchiver), re-zip the images, and upload the ZIP here. MangaSendr accounts can't open RAR-based CBRs either, so the same repackaging step applies.
What is the difference between CBR and CBZ?
Only the compression. A CBR is usually a renamed RAR archive and a CBZ is a renamed ZIP archive. Both contain a sequence of page images. ZIP is an open format, which is why CBZ works in places CBR doesn't.
How do I convert a CBR to CBZ?
Open the CBR in 7-Zip (Windows) or Keka or The Unarchiver (macOS) and extract the images to a folder. Select the images and compress them to a ZIP. That ZIP uploads here directly. Renaming it to .cbz is optional, because the converter treats both the same.
