Sign a PDF without an email address

Many e-signature services want your email address before you can sign, and then send the signed document to an inbox. OpenSigner never asks for an email address: the signed PDF is simply downloaded to your device, and you decide where it goes.

Questions

Where does the signed PDF go?

To your browser's downloads folder, the same as any other download. Nothing is emailed.

Can I sign on a shared computer without leaving traces?

Use a private or incognito window. OpenSigner remembers your signer name and last signature in local storage, and a private window discards it when closed.

Ready when you are.

Free, private, and nothing to install.
