For the smallest photo and signature upload boxes
Pre-filled: target 20 KB, JPG output. Change either once you add a photo.
20 KB is a tiny limit, the kind that appears on upload boxes for a signature, a small ID photo or a stamp on older government and university application forms. A modern phone photo is many times bigger.
No amount of quality loss alone gets a photo there, so the tool also makes the picture smaller. It tries quality first, then steps the pixel size down until the file fits. A small, plain picture such as a signature on white paper is easy; a detailed outdoor photo ends up at a few hundred pixels across.
If the form states exact pixel dimensions as well as the 20 KB limit, resize the photo with Edit image first, then compress. The result list shows the new pixel size whenever the tool had to reduce it, so you can check it against the form.
To reach 20 KB the picture can lose a lot of detail and size. Check it still looks right, and keep your original. If it cannot reach the target the result is marked as not reachable.
Compress image is a DocPro Pro tool on the web. You can open it, choose your file and set every option without an account; the final step asks you to sign in to DocPro Pro (A$5.99/month after a 7-day free trial, cancel anytime). Free tools never ask.
Usually yes if it is dark ink on plain white paper, cropped close. Crop first with Edit image, because blank margins use up pixels you need.
At this size, lowering quality is not enough, so the tool reduces the number of pixels. The result row shows the final width and height.
No. They are compressed in your browser.
