Quill is a place to sign your name. Draw your signature with a mouse, a finger, or a stylus, then export it as a PNG with a see-through background — ready to drop into a PDF, a contract, or an email. Nothing is uploaded; your signature is drawn and saved entirely on your device.

Trim to signature White background

The signature is drawn on your device and never uploaded. "Trim to signature" crops the export tightly around the ink; leave "White background" off for a transparent PNG that sits cleanly over any document. A drawn signature is convenient, but it is not the same as a legally certified digital signature — for that, use a dedicated e-signature service. Everything runs on your device.
