How to optimize, compress images for the web?

Question

linux

It is necessary to sort out and optimize, compress about 3GB of images.
There is an optimizer on the web _ https://tinypng.com/, I really like how it compresses, on average by 40-60%, is there something similar under linux to achieve a similar effect after compression?
You need exactly softwares that work in batch mode, from the command line, since there are about 50-60k files and there is no way to manually sort through them.
Maybe someone knows what the service above uses to optimize images? There is also PageSpeed ​​Insights from Google, which also compresses decently. What do they use, is it really some kind of individual development?
Now I'm looking in the direction of ImageMagick, but something tells me that such a compression result cannot be achieved with it
