How signing a PDF works
Sign PDF is a free browser-based tool that adds a personal signature to any page of a PDF — no printing, signing on paper, and scanning back in required. You create the signature one of three ways: draw it freehand with a mouse, trackpad, or finger; type your name and have it rendered in a signature-style font; or upload a photo or scan of the signature you actually use on paper. Once it's on the page, it stays fully editable — drag it to reposition, resize it from the corner handle, or duplicate it if you need to sign the same document in more than one spot.
This is built for casual, personal-use signing — acknowledging a document, signing off on something informal, filling in your signature on a form for your own records, or sending a document back without the printer-scanner round trip. It doesn't include the certified audit trail, timestamped chain of custody, or identity verification that dedicated legal e-signature platforms provide, so it isn't a substitute for those when a contract or other document specifically requires a certified signature. Everything — drawing your signature, rendering the typed or uploaded version, positioning it, and embedding it into the final file — happens locally in your browser. Nothing is uploaded to a server at any point, which also means it keeps working even on a slow or unreliable connection.
Common use cases
- Signing off on an informal agreement, acknowledgment, or internal memo
- Adding your signature to a personal form, waiver, or template
- Quickly signing a document to send back by email without printing it first
- Countersigning a document that a colleague or client has already signed
- Adding your signature to multiple pages of a longer document, like initialing each page
If the document needs a certified, legally binding signature with an audit trail — for a formal contract, for example — use a dedicated e-signature service instead. For everything else, this keeps your signature and your document on your own device from start to finish.

No. This is a casual, personal-use signature tool for things like signing off on a document informally. It doesn't provide the certified audit trail or identity verification that dedicated legal e-signature platforms (like DocuSign or Adobe Acrobat Sign) use for contracts, so it isn't a substitute for those when a legally certified signature is required.
Three: draw it with your mouse, trackpad, or finger on a touchscreen; type your name and have it rendered in a signature-style font with a color of your choice; or upload a photo or scan of your actual handwritten signature and place that image directly.
Yes. Click or tap a placed signature to select it, then drag it to reposition, or drag the handle in its corner to resize — it always keeps its original proportions so it never stretches or looks distorted. There's also a quick delete button on the signature itself for one-tap removal on mobile.
Yes. Place as many signatures as you need across any pages — switch pages with the page selector, and reuse a signature you've already placed with the duplicate button instead of creating it again from scratch.
No. Drawing, typing, rendering, and embedding the signature into your PDF all happen locally in your browser's memory. Your file and your signature are never sent over the network.
Yes. For a drawn signature, pick any pen color and stroke thickness. For a typed signature, choose from three distinct styles — classic script, a bold flowing look, or a neat handwritten-print style — in any color.
Nothing is final until you download. Drag a misplaced signature back into position, resize it, or delete it and place a fresh one — the PDF itself isn't touched until you click Download signed PDF.
