ImageMagick and FFMpeg usually do the trick.

I’ve already used them for some pretty crazy things.

Thanks! If you have any issues, just open an issue and I’ll have a look!

It has a really good compression algorithm and can preserve more detail in a smaller filesize.

As a website owner you usually pay for outbound traffic or atleast storage, thus having a smaller file reduces your cost, appart from the benefit that more users are able to load the file.

Thats why I built a tool that watches my download folder and converts webp and webm to png and mp4 preserving the original. Its still missing some features but its available on my GitHub for free as OSS
