How to convert CBR to EPUB
- Add your .CBR file - drop it in the box above or click to browse.
- Convert it to .EPUB in a few seconds.
- Download your new .EPUB file.
What to expect
- The output is always an image EPUB - pages are stored as raster pictures, so there is no selectable or searchable text.
- Page quality is fixed by the source scan; Calibre does not upscale or sharpen images.
- In Calibre's Comic options, set the output resolution to your device's screen size to reduce file size without visible quality loss on-screen.
Frequently asked questions
Does the comic page order stay correct after conversion?
Yes - Calibre sorts pages by filename before packing them into the EPUB, which matches how CBR readers display pages.
Why is the converted EPUB so large?
The EPUB contains the original scan images repackaged in a ZIP container. Set the target screen size in Calibre's Comic options to match your e-reader - this can cut file size by 60-80% with no visible loss on the device.
Can I convert several CBR files at once in Calibre?
Yes - select multiple books with Ctrl+click, right-click, and choose Convert books > Bulk convert, then set the output format to EPUB.
Pages look cut off or tiny on my e-reader - what went wrong?
This is a resolution mismatch; open Convert individually in Calibre, go to Comic options, set the screen size to your device's exact resolution, then reconvert and re-transfer the file.
