Is there a simple way to specify whether a webp is lossy (like jpg), lossless (like png), or animated (like a gif)?
For example, is it possible to name something "file.lwebp" to explicitly designate that it is lossy, or "file.awebp" to designate it is animated? Or is there no such method, and you just have to explicitly check the file?
