Kindle Comic Converter is a Python app to convert comic files or folders to ePub, Panel View MOBI or E-Ink optimized CBZ. It was initally developed for Kindle but since v2.2 it outputs valid ePub 2.0 so despite its name, KCC is actually a comic 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 readers. KC2 in no way is a replacement for KCC so you can be quite confident we'll 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.
If you want more chances an issue is fixes or your wanted feature added, consider placing a bounty!

You can find the latest released binary at the following links:

• Windows: http://kcc.vulturis.eu/Windows/
• Linux: http://kcc.vulturis.eu/Linux/
• OS X (10.8+): http://kcc.vulturis.eu/OSX/

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

• Folders containing: PNG, JPG, GIF, TIFF or BMP files
• CBZ, ZIP
• CBR, RAR (With unrar executable)
• CB7, 7Z (With 7za executable)
• PDF (Extracting only contained JPG images)

• KindleGen v2.9+ in a directory reachable by your PATH or in KCC directory (For MOBI generation)
• UnRAR (For CBR/RAR support)
• 7za (For 7z/CB7 support)

• Python 3.3
• PyQt5
• Pillow 2.3.0+
• psutil
• python-slugify

On Debian based distributions these two commands should install all dependencies:

sudo apt-get install python3 python3-dev python3-pip python3-pyqt5 libtiff-dev libpng-dev libjpeg-dev p7zip-full unrar
sudo pip3 install pillow python-slugify psutil

• Windows - cx_Freeze version 4.3.2 with this patchset.
• OS X - py2app HEAD version.

Should be pretty self-explanatory. All options have detailed informations in tooltips. After completed conversion you should find ready file alongside the original input file (same directory).

Please check our wiki for more details.
