A cross-platform C++ GUI application that compresses and reformats digital comics so they read well on e-readers and take up less storage. It reduces file sizes by up to 80% while improving visual fidelity, and is built with Qt, libVIPS, PDFium, and libarchive.

I started it to solve a problem I had: comic files were too large for my e-reader and looked worse than they needed to. Finishing it meant learning image processing I hadn’t set out to learn, because the project required it.
