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.
sometimes afaik you could still have success renaming the file to .gif or .gifv I think? Telegram and Whatsapp should also work afaik.
