I started using Squash a couple of hours back, and I see unexpected results.
It’s increasing the file size instead of reducing it. I downloaded this stock image for test: https://www.pexels.com/photo/close-up-photo-of-berries-1379636/
Then I set the JPEG Quality level to 95%
It increased the file size to almost double.
I set it back to the default 70%, and still, the size of the compressed file is marginally larger than the original file.
Also, the quality looks low to me. What I’ve experienced is, it increased the file size and reduced the quality.
