With this update, ACBR is now not only a reader but a converter of comic book files too.

Changelog:

• Added tools to:
  • Convert/Resize files from cbr, cbz, pdf or epub to cbz, pdf or epub.
  • Export the current page to an image file.
• Moved some of the cpu intensive work to child processes so the program doesn't feel unresponsive.
• Added a loading spinner image to indicate when something is loading.
• The file format is now deduced from the file data itself instead of from its extension (so, even if a cbz file is renamed to cbr it will be correctly detected as a zip compressed file).
• A bunch more of small performance and usability tweaks...
