How to use
Choose an image, select JPEG or WebP, set quality and maximum dimension, then process and compare the result size before downloading.
Privacy
Compression runs entirely in your browser. The selected image is not uploaded to our server.
Limitations
Lossy compression changes image data. Transparent pixels are not preserved when exporting as JPEG.
