Please, attach the images as a ZIP archive to make it possible to reproduce the issue :-)
Now we can't help because we do not have the images.
Cool, thanks.
It happens because banner-img-joy-smile-desctop-ok.jpg's Webp version is bigger than the original JPEG. By default Optimizt does not create new files if they are bigger than their originals, because it does not look like optimization.
That's why you get this:
$ optimizt --webp --avif .

But if you want to get AVIF or/and Webp files always regardless of the optimization result, then use --force flag:
$ optimizt --webp --avif --force .

As you see, created Webp version is 15% bigger than the JPEG. But it's still created because of --force flag use.
Ok, thanks. How can I specify for WebP optimization quality? For example: quality 50
It is not possible for now. Optimizt sets quality to 85 for JPEG/PNG → WEBP:

We will think about adding this feature in the future though 🤔
Also PRs are always welcome 🐨
