Who needs a photo under 10 KB?
Government exam and job application forms often ask for a signature or thumb impression between 10 and 20 KB. A phone photo is usually 2–5 MB, hundreds of times bigger.
Getting the best quality at 10 KB
Crop the photo tightly around the signature first, so the pixels go to the ink and not the paper. Write with a dark pen on plain white paper, and keep JPG as the format.
What size will the picture be?
About 300–450 pixels wide from a typical phone photo, which is sharp enough for a signature.
