Hi Product Hunt, I read manga on an e-reader, and getting files onto it properly means running Kindle Comic Converter: sizing pages to the device's exact resolution, dithering for e-ink, handling right-to-left reading and double-page spreads. KCC is excellent and does all of that. It is also a desktop app, so you install it on one machine and convert one file at a time there. MangaConverter runs the same engine in a browser. The part I use most is the live preview: you see the actual processed pages and they update while you adjust margins, dithering or splitting, so you stop converting blind and rechecking on the device. It handles CBZ, CBR, CB7, ZIP, RAR, PDF and EPUB, has around 35 device profiles (Kindle, Kobo with proper KEPUB, reMarkable, PocketBook, Onyx), and a batch queue for whole volume runs. It also recovers files that usually fail outright, like partially corrupt archives and archives nested inside archives. Free to use, uploads deleted within 24 hours, and the whole thing is open source and self-hostable with Docker if you would rather nothing left your network: https://github.com/NilsLeo/kcc-c... Credit where it is due: the conversion quality is KCC's work. I have contributed a few fixes back upstream while building this. Would love feedback, especially on device profiles I am missing.
