300×150px · 10–20 KBHow it works
- Upload a scan or photo of your signature (JPG or PNG, any size).
- We center-crop to 300×150 px on a white background and tune JPEG quality until the file lands between 10 and 20 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
- •10–20 KB is a narrow window — start from a clean, high-contrast scan rather than a dim phone photo.
- •Crop tight around the signature before uploading. Empty white margins waste your KB budget.
- •If the result looks faded, re-scan with more contrast rather than lowering the target size.
