Hit an exact size in KB
Set the size you need, for example 100 KB for a form upload, and the tool adjusts the quality to reach it. It works on one image or many, runs in your browser, and never uploads your pictures.
Enter 100 as the target and the tool tries to stay at or below it. Very small targets may need the image to be resized or may reduce the quality noticeably, and the results show the final size.
PNG can only be resized, not compressed to a size target, so choose JPG or WebP for the best size control.
No. Compression runs in your browser.
