Frequently asked questions
Is this a cryptographic digital signature?
No. This adds a visible electronic signature mark; it does not issue a certificate or cryptographically verify signer identity.
Can I sign a scanned form?

Can I sign on my iPhone?
Yes. Use a modern mobile browser to place the signature, then review the downloaded PDF.
Does this require an account?
Guests can upload files up to 25 MB each. A free account raises the limit to 50 MB per file, and Premium allows 500 MB per file with larger batches.
