+**Kindle Comic Converter** optimizes comics and manga for eink readers like Kindle, Kobo, ReMarkable, and more. 
+Pages display in fullscreen without margins, with proper fixed layout support. 
+Its main feature is various optional image processing steps to look good on eink screens, 
+which have different requirements than normal LCD screens.
+It also does filesize optimization by downscaling to your specific device's screen resolution,
+which can improve performance on underpowered ereaders. 
+Supported input formats include folders and archives of JPG/PNG files and more.
+Supported output formats include virtual panel view MOBI/AZW3, EPUB, KEPUB, and CBZ.

-**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.

utopiafallen	62ffa2bc80	Improve processing performance by partially undoing "Refactored detection of corrupted files" Commit `f952634971` moved image corruption detection out from the ComicPage constructor and into a standalone detectCorruption() function. This led to a performance regression because now corruption detection happens in a single thread when it used to be distributed across worker threads, and because a source image is now loaded twice in memory: once during corruption detection and once when actually going to process the image. Image file corruption detection is now back inside the ComicPage constructor and the extra load() has been removed because the convert() call will automatically invoke load() and most likely throw the same exceptions.	2025-02-28 19:49:13 -08:00
