How to use Image compressor

Drop an image. Choose JPG, WebP, or PNG and a quality slider. The preview updates so you can judge artifacts before downloading. Typical web hero images land between 80–150 KB at 1200px — pair with Image Resizer for dimensions.

Compress photos for the web, email, or app uploads. Watch the estimated size as you drag quality. Convert to WebP for even smaller files when the destination supports it.
