Quality
JPG and WebP saved a little lower

Compress and download
Each image keeps its format and size in pixels.
Which setting should I pick?
Balanced looks the same on screen for nearly every photo and screenshot. If a site still rejects the file, try Smallest file, or compress to an exact size.

How the image gets smaller
Each format has its own way to save space. The compressor uses the right one, and never hands back a bigger file.
Palette
PNG with fewer colours
Screenshots and graphics use far fewer colours than a PNG can hold. A smaller palette often cuts them by 60 to 90 percent, transparency kept.
Hidden data
Camera details removed
The camera model, date and GPS location are stripped. That saves space and makes the image safer to share.
