Converts manga, comics, and normal images into grayscale, Kindle compatible folders. It was inspired by Mangle, with the goal of being faster and producing better quality output.

• Faster. Convert images using all your CPU cores.
• Better quality dithering. Color images are converted into grayscale using high-quality dithering algorithms that better preserve shading.
• Zip/cbz support. Convert directly from zip files without having to extract them first.
• Newer Kindle support. There are options to output for the Kindle Keyboard, Paperwhite, and Voyage.

• Less options. There are currently no options to disable dithering or resizing, or to add borders around images.
• Windows only.
• The current UI is a bit silly.

In the comparison images below, notice how blotchy the face and clouds on the left are in the output from Mangle compared to the output from this software.
