About this tool

CBR is a comic book whose page pictures are stored in a RAR archive. FB2 (FictionBook) is an XML e-book format popular in Eastern Europe and Russia.

This converter turns your CBR file into FB2, the right choice for FBReader, PocketBook and other e-readers that read FB2. Every page of the comic stays a picture, in reading order, so the FB2 file shows it as drawn – there is no text to reflow. Add up to 10 files at once – each one is converted in the background, so you can keep using the site and download every result as soon as it is ready.

Documents are converted on our server: the upload starts only after you confirm, the original is deleted after conversion and the result is kept for 7 days unless you delete it sooner.
