Sign a PDF without uploading it FAQ
Is this a cryptographic digital signature?
No. It places a visual signature image onto the PDF. It does not create a certificate-backed digital signature or independently verify identity.
Where is my signature stored?
It is stored only in session storage for the current browser tab so you can reuse it during that session.
