About this tool
Sign PDF lets you place your name or a short signature line onto a document so it reads as executed or approved. It is the lightweight alternative to full e-signature platforms when you simply need to mark a page as signed — for an internal approval, a cover sheet, or a casual agreement. The tool overlays your typed name across the page in your browser, so the document never leaves your device. We are clear this is a visual stamp, not a cryptographically secured digital signature; for legally binding signatures you should use a dedicated e-sign service. But for everyday “signed and sent” marking, it is instant and private. No account, no upload. Type your name, choose a spot, and download the marked PDF — done in seconds on your own machine.
A visual signature is enough more often than people expect. An internal approval needs a name on the cover sheet. A casual agreement between friends is sealed with a typed sign-off. A draft is marked “signed — pending review” before routing. A homeowner initials a permission slip digitally. A freelancer stamps a deliverable as accepted. None of these require the machinery of a paid e-sign platform; a clear name mark does the job and keeps the file moving. Doing it locally means the document — perhaps a contract or personal letter — never uploads, which suits the private nature of signatures. We are candid that this is not a legally secured digital signature; for binding agreements, a dedicated service is the right tool. For everyday marking, this is fast, free, and private.
How it works & privacy
Type the name or text you want as a signature and press Run. The tool opens your PDF in the browser with pdf-lib and overlays the text where you choose, then downloads the result. Nothing is uploaded. This is a visual stamp, not a secured digital signature, so we are open about when a dedicated e-sign service is the right call.
