Shrink a heavy image to a sensible size, with the saving shown before you download.
Bring a heavy JPG or PNG down to a friendlier size for the web or email. Drop an image, choose JPEG or WebP, and slide the quality until the size and the look feel right. You see the saving before you download.
WebP usually makes smaller files at the same quality and is supported everywhere modern. JPEG is the safe, universal choice. Your image is processed in the browser and never uploaded.
That's the whole list. A short note when there's something new worth your time. Leave whenever you like.
