How to optimize images?

Hello! The essence of the question:
PageSpeed Tools from Google requires optimization.
For example, image size 200KB 1920х1050 weighs after compression using tinypng.
Google says that can be reduced by 98%! percent. How so? What other SEOs to use?

exercise your thinking and see the competitors

about 98% of Google speaks for idiots, display 1900*1200 image in 240*360 box

mobile users happy
Thank God for idiots, I am not myself because of the huge pictures I don't appear as you described. Otherwise, I would I did not ask the question - ofelia.Botsford commented on July 2nd 19 at 17:31
: well, actually Google on the exact same page provides a link to the archive pregatiti materials. that's it, and download and insert this picture instead of yours. - Haley0 commented on July 2nd 19 at 17:34
: this is not to you specifically, sorry if well written ))
in General the speed is important for cores to 100% on multi-page sites we constantly see, so all that remains is to adapt to Google

the easiest way is to feed a suitable competitor page and then parse what you got in sravnenii wrong with her - Juanita17 commented on July 2nd 19 at 17:37
: Not an option. Wrong images it makes. Pixelate turns - ofelia.Botsford commented on July 2nd 19 at 17:40
: Yes now, if Google even really picture correctly have a daughter, I would not mind. And the slider 200 needs 200 to be used pictures, and he half 90 90 makes... - ofelia.Botsford commented on July 2nd 19 at 17:43

Do not listen to this advice of Google. Like it or squeeze the image, Google believes that you can shrink else. I suspect that the perfect image is a GIF with uniform shading.
No, ideally, according to Google, will be a single-pixel picture to 8-bit unsupported format - ofelia.Botsford commented on July 2nd 19 at 17:33

Use Save for web in photoshop. Set the minimum number of colors, maximum compression in which image quality does not suffer.

The image resolution of the disc and the img tag must match.
Photoshop does not optimize under Google.
Use jpegoptim, jpegtran, optipng. In doing so and Google takes.
