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.
Edit: honestly I assumed it had something to do with Google protecting themselves from image piracy shit
Yes. The problem is getting developers/companies to support anything beyond than just the basics. There’s enough formats that could work, but if the big players only support these formats, everything else is secondary. Just like many music players still play only mp3.
