- always saves processed comic in CBZ (ZIP) archive format
- images can be converted to JPEG, PNG, GIF or 4-Bit BMP (16 colors) file format
- reads JPEG, PNG, BMP, GIF, TIFF and WEBP file formats
- choose resize algorithm (NearestNeighbor, Bilinear, Bicubic, MitchellNetravali, Lanczos2/3)
- choose resize algorithm (NearestNeighbor, Box, Linear, MitchellNetravali, CatmullRom, Gaussian, Lanczos)
- export covers from comics
- create thumbnails from covers by [freedesktop](http://www.freedesktop.org/wiki/) specification
