About this tool
PNG files do not lose quality, so they are often very large and a quality slider cannot shrink them much. The best way to make a PNG small is to save it as WebP, which keeps transparent backgrounds and is usually far smaller. This page does that for you in your browser. If a form only accepts PNG, check the size first, because the PNG itself will stay large.
Questions people ask
Does it keep the transparent background?+
Yes, with WebP and PNG. JPG cannot be transparent, so those areas turn white.
Why does the quality slider not shrink my PNG?+
PNG saves every pixel exactly, so quality settings do not apply. Saving as WebP or JPG is what makes the file smaller.
