GitHub release GitHub Workflow Status

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.

A word of warning

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 ;-)

Click on Assets of the latest release.

You probably want either

  • KCC_*.*.*.exe (Windows)
  • kcc_macos_arm_*.*.*.dmg (recent Mac with Apple Silicon M1 chip or later, macOS 14 Sonoma or later)
  • kcc_macos_i386_*.*.*.dmg (older Mac with Intel chip, macOS 12 Monterey or later)

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:



You'll need to install various tools to access important but optional features. Close and re-open KCC to get KCC to detect them.


Windows / macOS KindleGen

Install Kindle Previewer and kindlegen will be autodetected from it.

If you have issues detecting it, or use another OS, refer to the wiki:


This is no longer required as of KCC 6.1.

If you still need it, refer to the wiki:


KCC can understand and convert, at the moment, the following input types:

  • Folders containing: PNG, JPG, GIF or WebP files
  • CBZ, ZIP (With 7z executable)
  • CBR, RAR (With 7z executable)
  • CB7, 7Z (With 7z executable)
  • 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

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.

Windows install from source

One time setup and running for the first time:

python -m venv venv
pip install -r requirements.txt

Every time you close Command Prompt, you will need to re-activate the virtual environment and re-run:


macOS install from source

One time setup and running for the first time:

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Every time you close Terminal, you will need to reactivate the virtual environment and re-run:

source venv/bin/activate


KCC is made by

This script born as a cross-platform alternative to KindleComicParser by Dc5e (published here).

The app relies and includes the following scripts:



KCC is initiating internet connections in two cases:

  • During startup - Version check.
  • When error occurs - Automatic reporting on Windows and macOS.
