KindleComicConverter is a Python app to convert comic files or folders to ePub or Panel View MOBI. 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. If you want to read some comments over Amazon's KC2 you can take a look at this and that threads on Mobileread. 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 ;)

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

• Win64: http://kcc.vulturis.eu/Win64/
• Win32: http://kcc.vulturis.eu/Win32/
• OS X: http://kcc.vulturis.eu/OSX/
• Linux: Just download sourcecode and launch: python kcc.py

It has been reported by a couple of users that version 2.10 crashing on OSX at start. We don't know if that issue still exist in version 3.0. If it happens to you please append your message to Issue #52.

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

• PNG, JPG, GIF, TIFF, BMP
• Folders
• CBZ, ZIP
• CBR, RAR (With unrar 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)

• Python 2.7 - Included in MacOS and Linux, follow the official documentation to install on Windows.
• PyQt4 - Please refer to official documentation for installing into your system.
• Pillow - For comic optimizations. Please refer to official documentation for installing into your system.

• Use high quality source files. This little detail have a major impact on the final result.
• Read tooltip of High/Ultra quality option. There are many important informations there.
• When converting images smaller than device resolution remember to enable upscaling.
• Check our wiki for a list of tested Non-Kindle E-Readers.
• The first image found will be set as the comic's cover.
• All files/directories will be added to EPUB in alphabetical order.
• Output MOBI file should be uploaded via USB. Other methods (e.g. via Calibre) might corrupt it.
• If you're converting color images and the end result is not satisfactory, experiment with gamma correction option (check 1.0 setting first).

Should be pretty self-explanatory. After completed conversion you should find ready file alongside the original input file (same directory).
