Kindle Comic Converter is a Python app to convert comic/manga files or folders to EPUB, Panel View MOBI or E-Ink optimized CBZ. It was initially developed for Kindle but since version 4.6 it outputs valid EPUB 3.0 so despite its name, KCC is actually a comic/manga to EPUB converter that every e-reader owner can happily use. It can also optionally optimize images by applying a number of transformations.
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 ;-)
If you have general questions about usage, feedback etc. please post it here. If you have some technical problems using KCC please file an issue here. If you can fix an open issue, fork & make a pull request.

You probably want either
KCC_*.*.*.exe(Windows)kcc_macos_arm_*.*.*.dmg(recent Mac with Apple Silicon M1 chip or later)kcc_macos_i386_*.*.*.dmg(older Mac with Intel chip)
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
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 only 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:

This section is for developers who want to contribute to KCC or power users who want to run the latest code without waiting for an official release.
Easiest to use GitHub Desktop to clone the KCC repo. From GitHub Desktop, click on Repository in the toolbar, then Command Prompt (Windows)/Terminal (Mac) to open a window in the KCC repo.
Depending on your system Python may be called either python or python3. We use virtual environments (venv) to manage dependencies.
If you want to edit the code, a good code editor is VS Code.
If you want to edit the .ui files, use Qt Creator, included in Qt for desktop development.
Then use the gen_ui_files scripts to autogenerate the python UI.
One time setup and running for the first time:
python -m venv venv
venv\Scripts\activate.bat
pip install -r requirements.txt
python kcc.py
Every time you close Command Prompt, you will need to re-activate the virtual environment and re-run:
venv\Scripts\activate.bat
python kcc.py
One time setup and running for the first time:
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python kcc.py
Every time you close Terminal, you will need to reactivate the virtual environment and re-run:
source venv/bin/activate
python kcc.py
