Our experience with it 472KB to 164KB

TinyJPG

Its same as the later one but the only difference is, it support only JPG formats of maximum size 5MB, we have also tried this one and level of compression was good like their former service. Now you can now use anyone of their website to shrink both the formats which was not possible back in 2013.

Jpegmini

Like the previous tool this one is quite handy with drag and drop interface for only jpeg formats. Moreover you will shown a side to side comparison with the quality of image. Even though you didn’t see much change in quality, try to zoom in you will see some loss in the quality but it won’t be a problem to many of us.
