Supported formats

Document Viewer supports the following formats:

  • Comic Book Archive (.cb7, .cbr, .cbt, and .cbz)

  • DjVu (.djvu, .djv)

  • Portable Document Format (.pdf)

In some Linux distributions, not all formats are supported by default, so you might not be able to view all the formats listed above.

Support for a format is called a backend. If you get the error "Unable to Open Document", you may wish to check whether the backend package for the format is installed.
