Frequently asked questions
How much smaller can files get?
It depends: photographic JPGs typically drop 50–80%; PNGs far less.
Does the image lose quality?
JPG and WEBP are lossy — that's why the preview shows the result before you download.
Will this speed up my website?
Yes. Lighter images directly improve page load time.
