When to Convert
Common scenarios where this conversion is useful
Read Comics on a Kobo or Standard E-Reader
Most Kobo, PocketBook, and other e-readers support EPUB but not CBR natively. Converting your CBR comic collection to EPUB lets you read them directly on your preferred e-reader without installing a separate comic app.
Add Comics to an Ebook Management Library
Calibre and other ebook managers organize EPUB files with full metadata support. Converting CBR to EPUB lets you catalog your comic collection alongside your ebook library with consistent author and title information.
Send Comics to Read-It-Later or Ebook Apps
Many ebook apps like Apple Books or Google Play Books accept EPUB files. Converting CBR to EPUB allows you to import digital comics into apps that do not support the CBR format natively.

Frequently Asked Questions
A CBR (Comic Book RAR) file is a RAR archive containing sequential image files — typically JPG or PNG — representing pages of a comic book or manga. The CBR extension signals to comic readers how to display the images in order.
Calibre extracts the image files from the RAR archive and packages them into an EPUB container. Each comic page becomes a page in the EPUB. The result is a fixed-layout EPUB with the original comic images embedded.
Calibre embeds the original images into the EPUB without re-encoding them by default. Image quality should be identical to the original CBR file.
Kindles support EPUB (on newer models with firmware 5.16.6+) and MOBI/AZW3 on older models. For the best Kindle experience with comics, consider converting CBR to CBZ first, then using the Kindle's built-in comic support, or convert to EPUB for non-Kindle e-readers.
Yes. Calibre preserves the alphabetical/numerical order of images within the CBR archive, which corresponds to the correct reading order for most comic book files.
Calibre can set the reading direction for the output EPUB. The default output may be left-to-right. For manga, you may need to set the reading direction in Calibre's conversion settings if using the desktop app.
EPUB adds an XML container structure, metadata files, and navigation documents around the images. The images themselves are the same size, but the overhead makes the EPUB slightly larger than the raw CBR.
No. Your file is automatically deleted from our servers immediately after conversion. We do not retain any comic book content or personal data.
ChangeThisFile supports files up to 50MB. High-resolution comic archives can be large; if your CBR exceeds 50MB, consider compressing the images before uploading.
Yes. ChangeThisFile also supports CBZ to EPUB conversion. CBZ uses ZIP compression instead of RAR, but the comic page content and conversion result are equivalent.
