How to optimize images for Google Page Speed?

Question

linux

Hello, there is such a question about image optimization, at the moment I am optimizing images on the server using two utilities optipng and jpegoptim, which compress images by 20 percent maximum. But the same Google PageSpeed ​​says that you can compress even more. Using the service https://tinypng.com it turns out to compress the image without losing quality by 80-90%. The question is what software do they use to compress so much? How to compress an image by 80% without losing quality??

Answer 1

The correct solution is not to compress images under Google page speed. And do it according to your requirements for their quality. If you compress to what Google specifies, everything looks like crap. You can't compress without losing quality.

Somewhere before, there was even such a class.

For png, try pngquant, it compresses noticeably better optipng
jpegoptim compresses without loss of quality by default, while tinypng clearly reduces it. You can either set the quality you need through the -m option, or generally specify the size you want to get through the -S option.
