Is there a simple way to specify whether a webp is lossy (like jpg), lossless (like png), or animated (like a gif)?

Question

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?

Answer 1

Naming the file with a different extension will have no effect on its contents.

Specifically, adding or removing characters from the file's extension will not change the image's compression ratio or change whether or not the image is animated.
