+Pretty good service if you want minimally sized photos: my 100% quality JPEGs compressed to ~60% of their original size with only a slight decrease in overall sharpness. File size from Google's image compression from Google's [pagespeed tool](https://developers.google.com/speed/pagespeed/insights/) was smaller by ~10%, but the quality was noticeably lower in comparison. For my use case, I only compressed the resized photos and thumbnails used on the front page of my site to improve page load speed.
