What is Image Compression?

Image compression is a process that reduces the file size of an image without significantly degrading its visual quality. Our tool uses smart **lossy compression** techniques to selectively decrease the number of colors in the image, allowing you to store more images and load web pages faster.

How It Works

Drag and drop your JPG or PNG image into the box. We support files up to 10MB.
