This is something I wrote because nothing satisfactory existed. This takes a webp image or animation, and converts it back into a gif or a png.
(because the libunwebp tools do NOT do the reassembly part, and neither *magick nor ffmpeg do either) Even though it's a small tool, I think it's important to keep the web free of locked down formats, even when they're locked because google just didn't bother to supply the unlock code...
