Printing a document just to sign it and scan it back in is one of the more pointless steps still hanging around in paperwork. PDF Guru's sign tool lets you draw, type, or upload a signature image, then place it exactly where it needs to go on a contract, form, or agreement - all inside your browser. You can add initials on multiple pages, date fields, and a final signature block without leaving the tab.
Because signing happens locally in the browser session, the document isn't routed through a third-party signing platform or stored on a server afterward, which is reassuring when you're signing leases, NDAs, or client agreements. Once placed, the signature becomes part of the PDF itself, so the file can be downloaded and sent on immediately, ready for the other party to open in any PDF viewer.
