I don’t know what a .webp file is but I don’t like it. They’re like a filthy prank version of the image/gif you’re looking for. They make you jump through all these hoops to find the original versions of the files that you can actually do anything with.
Okay but that difference is not as critical as with jpg, which are also more abundant. The bigger problem with png is that people use it for things it’s not meant or designed for - frame of a video being case in point.
If anything, it just proves how lacking we are in other image formats, when we keep shoehorning clipart formats like png and gif into other duties. Well not lacking as in not having them, but not using them.
