PDF Signature

Model:
Visual signature only, not cryptographically binding. It places your typed name with an underline (and the date, if you want it) in one corner of a page you pick. Think of it as printing the file, signing in pen and scanning it back. If you need a legally binding e-signature backed by a PKI / PFX certificate, use Adobe Acrobat or DocuSign.
Up to 50 MiB.
Rendered in italic dark blue, with an underline beneath. Max 80 characters.
1-indexed; -1 = last page.
~200 tokens per use

Visual stamp via pdf-lib. For PKI-backed digital signatures, use Adobe / DocuSign.
