Because it's not exactly intuitive creating APNGs for command briefing animations, head animations and other files, User:qweqwe321 created (completely vibe-coded, don't @ me) to convert and resize MP4 videos into APNGs, and another tool to reverse APNGs in bulk. (Reversed APNGs is a niche use case - but it's very, very useful for head animations.) Windows-only, written in Python.

Note: CBAnims are usually 586x384. Head animations are hard-coded at 160x120.
