You can never have enough image compression apps. I recently started using JPEGmini when I wanted to compress old images on this blog and am really happy with the results.
My go to app ImageOptim has integrated Google’s Guetzli JPEG encoder into it’s latest beta and the results are unbelievable.
Google just announced Guetzli, an open source JPEG encoder which promises file sizes as much as 35% smaller with no visible quality loss.
