Image Compressor
Shrink an image's file size while controlling the quality trade-off yourself.
Compression re-encodes the image as JPG, which does not support transparency — transparent areas will become white.
Processing happens locally in your browser. Nothing you enter is uploaded.
How It Works
Choose an image and adjust the quality slider. The compressed size updates live, and you can download the result.
Example
A 3MB photo compressed at 80% quality often drops to under 500KB with minimal visible difference.

- Why does the output look different from a transparent PNG?
- Compression re-encodes as JPG, which doesn't support transparency — transparent areas become white.
