optimise-images.sh missing "badly optimized" webp removal script?

Hello and thanks again for this awesome tool that is CMM!

Quick question :

As you probably know, a very-well optimized png (in my case : logos, which went through png64 and ImageOptim.app on osx), will be converted into a BIGGER webp file.

Thus, I'm wondering if optimise-images.sh shouldn't have a "cleanup" routine which would:

- go through all the png/jpg "original" images
- compare these with their "webp" versions
- delete the webp version if the webp version is bigger than the original

Later on, the nginx vhost configuration would revert back to serving the original "better than webp" file format since the webp has been deleted.

What do you think?

Or maybe it's already there and I didn't see it lol, optimise-images.sh is very powerful so maybe I missed a step somewhere.

I'll see if I can find someone to create this bash script and share it with you if it's really missing.

Cheers,

 

I know if png AND webp are there, nginx will serve the webp to webp enabled browsers, thus the need to delete the "bigger" webp if it's bigger than the PNG. That's what I meant as "revert back" (basically it's what the try_files $uri$webp_extension $uri =404; is doing).

I'll generate a few example PNGs for you.

 

OK so obviously when I try to recreate the scenario, I don't get a high enough size difference so I'll PM you my real-world images.
