About WebP to PNG conversion
PNG is a lossless format accepted by almost every editor and design tool. Converting from WebP keeps transparency intact.
The PNG will usually be larger than the WebP, because PNG doesn't use lossy compression.
Animated WebP files are converted from their first frame. Vimorby flags them when you add them.
