Phone photos usually shrink by 50 to 80% with no visible difference. Screenshots and graphics saved as PNG often shrink by 60 to 80%. Every file shows its exact saving, and the total is at the top.

Enter a size such as 100 KB. FotoJock chooses the picture size and the quality together: quality stays where the photo looks clean, and the picture gets the largest size that still fits, filling 95 to 100% of the limit. 20 KB holds about a 450 px photo, 100 KB about 1000 px. If a form asks for exact pixels, choose “Exact pixels” and only the quality changes.
