400×200px · 20–50 KBHow it works
- Upload a scan or photo of your signature (JPG or PNG, any size).
- We center-crop to 400×200 px on a white background and tune JPEG quality until the file lands between 20 and 50 KB.
- Download and upload it straight to the form.
Everything runs on your device — your signature is never sent to a server.

Getting the scan right
- •With a 50 KB budget you can scan at higher resolution — 400×200 px keeps the strokes smooth.
- •Still crop out empty margins; they add file size without adding information.
