How to do it, step by step
-
Upload your images
Drag in one or several photos. They are all processed at once.
-
Adjust the quality
Move the slider between 20 and 95. Between 70 and 80 is usually where the file gets far lighter without showing.
-
Pick the format
If your image is a PNG, switching to WEBP cuts far more weight than keeping the original format.
-
Compress and download
You will see the before and after size of each image so you can check how much you saved.
