About the Compress Image to KB (20 KB, 50 KB, 100 KB…)

Online forms often say “picture must be less than 50 KB” or “under 100 KB”. Choose the size, add your photos and get files just under it with the best quality that fits. The tool first lowers the JPG quality, and only if that is not enough it makes the picture a little smaller.

Pick 20, 30, 50, 100, 150, 200, 300 or 500 KB, 1 MB, or type your own number. Save as JPG (accepted everywhere) or WebP (smaller, for websites). You can also limit the largest side in pixels when a form asks for a maximum width.

Many photos at once are fine; they come back in a ZIP. Nothing is uploaded.
