Drop in as many pictures as you like. Choose a preset - Instagram square, story, YouTube thumbnail, Etsy listing, a maximum width for a website - or type your own size. Every picture is resized and recompressed, and the table tells you what each one was, what it is now, and how much you saved.
Three ways to fit: keep the whole picture inside the frame, fill the frame and crop the edges, or stretch to the exact size. Fill-the-frame always gives you the exact dimensions you asked for, and anything that had to be scaled up is marked so you are not surprised by a soft picture later.
JPEG, WebP or PNG out. WebP is usually a third smaller than JPEG at the same quality and every current browser reads it.
Save them all at once as a zip, or one at a time. The zip is built in your browser like everything else.
Your pictures are read straight off your disk by the browser. They are not uploaded, not queued on a server and not held anywhere - which is the difference between this and every free compression site, all of which have a copy of whatever you gave them.
Comes with a three-page setup guide: which quality setting to use, when WebP is the right answer, and the sizes each platform actually wants.
