What media and devices work?

Komga supports these media file types

Komga supports the following file types:

  • Comic book archives: CBZ and CBR (except solid archives, for RAR5 see below)
  • eBooks in EPUB format
  • PDF files

RAR 5 is supported on some platforms only, as it relies on native libraries for decoding.

When using the jar, you will need to provide the native library yourself, and run Java with the correct arguments. You can check for more details here.
