Resize an image to 20KB online
Exam and job application forms often ask for a passport photo or signature under 20 KB. This tool compresses your image until it fits, and keeps it as clear as the limit allows.
JPG gives the smallest files for photos. A signature in dark ink on a white background compresses very well and stays sharp.

Frequently asked questions
Why do forms need a 20 KB image?
Small limits keep large numbers of applications quick to upload and store.
Will my signature stay readable?
In most cases, yes. High-contrast signatures compress well. Crop the scan to the signature first so no space is wasted.
What if the image is still above 20 KB?
Crop away empty space or start from a smaller original, then try again. Very detailed photos need more room than 20 KB allows.
