KCC is not Amazon’s Kindle Comic Creator nor is in any way endorsed by Amazon.
Amazon’s tool is for comic publishers and involves a lot of manual effort, while KCC is for comic/manga readers.
KC2 in no way is a replacement for KCC so you can be quite confident we are going to carry on developing our little monster ;-)

The c2e and c2p versions are command line tools for power users.
On Windows 11, you may need to run in compatibility mode for an older Windows version.
On Mac, right click open to get past the security warning.
For flatpak, Docker, and AppImage versions, refer to the wiki: https://github.com/ciromattia/kcc/wiki/Installation
- Windows 7 support
- Combine files/chapters
- Flatpak mobi conversion stuck
- Image too dark?
- The default gamma correction of 1.8 makes the image darker, and is useful for faded/gray artwork/text. Disable by setting gamma = 1.0
- Better PDF support (Humble Bundle, Fanatical, etc)
You’ll need to install various tools to access important but optional features. Close and re-open KCC to get KCC to detect them.
On Windows and macOS, install Kindle Previewer and kindlegen will be autodetected from it.
If you have issues detecting it, get stuck on the MOBI conversion step, or use Linux AppImage or Flatpak, refer to the wiki: https://github.com/ciromattia/kcc/wiki/Installation#kindlegen
This is optional but will make conversions much faster.
This is required for certain files and advanced features.
KCC will ask you to install if needed.
Refer to the wiki to install: https://github.com/ciromattia/kcc/wiki/Installation#7-zip
KCC can understand and convert, at the moment, the following input types:
- Folders containing: PNG, JPG, GIF or WebP files
- CBZ, ZIP (With
7zexecutable) - CBR, RAR (With
7zexecutable) - CB7, 7Z (With
7zexecutable) - PDF (Only extracting JPG images)
Should be pretty self-explanatory. All options have detailed information in tooltips.
After completed conversion, you should find ready file alongside the original input file (same directory).
Please check our wiki for more details.
CLI version of KCC is intended for power users. It allows using options that might not be compatible and decrease the quality of output.
CLI version has reduced dependencies, on Debian based distributions this commands should install all needed dependencies:
sudo apt-get install python3 p7zip-full python3-pil python3-psutil python3-slugify
