Frequently Asked Questions
JPG and WEBP compression is lossy, meaning some quality is traded for smaller files. At 80% quality the difference is virtually invisible to the human eye. PNG compression is lossless but produces larger files. For aggressive targets like 10 KB, there may be visible quality loss on large photos.
If even the lowest quality still exceeds the target, the compressor will also scale down the image dimensions to reduce file size further. You will always get a file at or below the requested target.
WEBP generally produces the smallest files at the same visual quality. JPG is a close second and has universal compatibility. PNG is best when you need transparency or lossless output but creates larger files.
