Sign a PDF — draw, type, or upload
Add your signature to a PDF in three ways: draw, type, or upload an image. Place it anywhere, then download.
Files are processed entirely in your browser. Nothing is uploaded to any server.
About this tool
Signing a PDF used to mean printing it, putting pen to paper, scanning it back, and emailing it as an attachment. Sign PDF compresses that to a single browser tab: upload the document, create your signature, place it on the page, and download the signed file. Three signature styles are supported — drawing with a mouse or finger, typing your name in a script font, or uploading a photo of your handwritten signature.
Once a signature is created it can be dragged to any position on any page and resized to fit the signature line. Multiple signature placements are allowed, which is useful for documents that require initials on every page as well as a full signature at the end. Signatures are stored in browser local storage so you can reuse them across sessions without redrawing.
This tool produces an electronic signature — a visible mark on the page. It is not a cryptographic digital signature with a certificate authority. Electronic signatures are legally recognised for most everyday contracts in many countries, but if your specific use case requires a certificate-based signature, you will need a dedicated signing service. For everything else — NDAs, rental agreements, offer letters — this tool handles it in under a minute.
