Frequently asked questions
Is it safe to sign a PDF with Signa?
Yes. Signa runs entirely in your browser: the PDF is opened and signed locally, there is no back-end, and no file is ever uploaded or stored.
Do I need an account, or to pay?
No. Signa is free, asks for no sign-up, email or card, and puts no limit on how many documents you sign.
Is the signature legally binding?
Signa stamps a handwritten signature onto the PDF, the digital equivalent of signing and scanning a page. It does not issue a digital certificate or a cryptographic signature; if your document requires one, use a certificate-based service.
Does it work on a phone or tablet?
Yes. On touch screens you draw the signature with your finger or a stylus.
Is the original file modified?
No. Signa produces a new file ending in _signed and leaves the original untouched.
