Frequently asked questions
Is this a legally binding digital signature?
It places an image of your signature on the page, like signing on paper. It is not a certified digital signature.
Can I choose which page to sign?
Yes. Pick the page, tap where the signature should go and adjust its size.
Are my files uploaded anywhere?
No. This tool runs in your browser, so your file stays on your device and is never sent to a server.
