It shrunk it 1.5x. I downloaded the _mini version and could see more artifacts in the rendering of some of the smooth surfaces.
Then I re-uploaded the _mini version to jpegmini. It shrunk it 1.3x. This shows that they are reducing quality, not just optimizing.
- colanderman 15y agoGiven that they claim to perform perceptual optimization, I would expect this. Human perception wouldn't come into play if they were just optimizing the image.
