What Sign PDF does
Sign PDF lets you draw or type a signature and place it anywhere on a PDF page, embedding it as a visual signature image.
Most documents that need "signing" need a signature that looks like your signature: a delivery note, an internal approval, a school form, a rental agreement. The usual routine — print, sign, scan, email — is absurd, and the alternative is normally uploading the document to a signing service.
Draw your signature with a mouse or finger, or type your name and have it set in a script style. Then drag it onto the page, resize it from the corners, and apply. It works on a phone, which is where a drawn signature actually looks like a signature.

Sign PDF: details and limits
This is a visual signature for everyday, informal use. It is NOT a cryptographic or legally-binding electronic signature: it carries no identity verification and no tamper-evident certificate. For contracts that must stand up legally, use a qualified e-signature provider.
The signature is placed on the page you are currently viewing, so navigate to the right one before applying.
Drawing works with touch, so signing on a phone gives a far more natural result than a mouse.
Your signature and your document are handled entirely in your browser — neither is uploaded, and no signature is kept on file afterwards.
