Compress a JPG
Large JPG photos slow down websites and bounce off email size limits. Compressing a JPG re-encodes it at a lower quality setting and strips bloat, often cutting the file by half or more with no difference your eye can detect. You stay in control of the quality so you decide where to stop.

Frequently asked questions
How much smaller can a JPG get?+
Photos commonly shrink 50–70% at a quality that still looks identical. Already-optimized JPGs save less.
Does compressing a JPG twice hurt it?+
Each lossy re-save adds a little degradation, so compress from the original once rather than repeatedly.
