Compress a signature JPG below 20 KB with optional exact dimensions for an upload form.

Make a signature small enough for a strict upload limit.

Use the 20 KB ceiling as a starting preset, then enter the exact pixel dimensions printed by the form. A tight crop around the signature usually preserves readability better than simply lowering JPEG quality.
