Questions

Before you sign

Can I scan a handwritten signature from paper?

Yes. PDF Sign & Scan uses the iPhone camera to capture a signature, removes the paper background on device, and saves the cleaned result for reuse.

Can I export the signature as a transparent PNG?

Yes. Open the signature library, use the signature actions menu, and choose Export as PNG.

Does the app create a certificate-based digital signature?

No. It places your handwritten electronic signature and exports a flattened PDF. It does not issue certificates or create a cryptographic digital signature.

Where are my documents and signatures stored?

The app stores them on your device. There is no account and no document cloud upload in the signing flow.

Your real signature, ready when the PDF arrives.

Scan it once. Place it carefully. Send the signed copy from your iPhone.
