Signing a one-off document shouldn't require signing up for something
Full e-signature platforms like DocuSign are built for recurring business workflows — multi-party routing, audit trails, integrations — and require an account to match. For signing a single lease, form, or agreement, that's a lot of setup for one signature.
PrivaPDF's sign tool needs no account: open it, draw or type your signature, place it, download the signed PDF. If you only need to sign something once and move on, there's nothing to set up and nothing to remember to cancel later.
