What is Image Compressor?
An image compressor reduces file size by re-encoding the image more efficiently, trading a small amount of visual quality for a much smaller file.

Frequently asked questions
How do I compress an image to 100 KB?
Choose Target size, enter 100 KB and compress. If 100 KB isn't reachable at full size, you can allow the tool to reduce the dimensions.
Will my photo look worse?
At the recommended quality, differences are usually hard to see. Use the comparison slider to check.
