About Compress Image
Shrink a photo's file size so a web page loads faster or an email attachment fits under a limit, while keeping the image looking essentially the same. Especially useful for large photos straight off a phone camera.

Tips
Photos usually tolerate moderate compression well; screenshots with sharp text or fine lines show artifacts sooner, so use a lighter setting for those.
If you're publishing to the web, compressing to under a few hundred KB is often enough for a noticeable speed improvement.
Compress after cropping or resizing, not before — a smaller image compresses to an even smaller file.
