Img Compress

Make image files smaller with little visible loss in quality. Images are processed in your browser and never uploaded.

Output format

Quality 80

Maximum size

Drop images here or click to choose JPEG, PNG, WebP, AVIF · several at once · you can also paste with Ctrl+V

Quality 75–85 is usually indistinguishable from the original. For PNG, quality sets how many colors are kept (80 keeps about 200); 100 keeps them all. Photo metadata such as location is removed. If an image would not get smaller, the original is kept.
