Sign PDF

Draw your signature (or upload an image of it), drag it into place on the page preview, and download the signed PDF. The document and signature never leave your browser.

Sign a PDF without uploading it anywhere

The popular e-signature sites make you upload the contract, then store it, email about it, and upsell you a subscription on the way out. When all you need is your signature on a page, none of that is necessary. This tool renders the PDF in your browser, lets you draw or upload a signature, place it precisely, and re-saves the file locally — the network stays out of it entirely.

How to sign

  1. Drop your PDF onto the panel.
  2. Draw your signature with a mouse, trackpad, finger or stylus — or upload a PNG/JPEG of it.
  3. Click anywhere on the page preview to position the signature, drag it to fine-tune, and size it with the slider.
  4. Click Sign & download. The signature is drawn into the page itself.

Visual signatures vs. digital signatures

What this tool applies is a visual (electronic) signature — an image embedded in the page, like ink on paper. A digital signature in the cryptographic sense additionally binds the document to a certificate and detects tampering; that requires certificate infrastructure and is deliberately out of scope here. For most everyday agreements the visual form is what's expected. If the document has form fields to complete first, fill them with the PDF Form Filler — and if the finished file is sensitive, lock it with the Protect PDF with Password tool before sending.

Frequently asked questions

Is my document uploaded to sign it?

No. The PDF is previewed and modified entirely in your browser — the file, and your signature, never touch a server. Contracts and agreements are exactly the documents you shouldn't hand to a random website to countersign.

Is this a legally binding signature?

It places a visual signature image, the electronic equivalent of signing with a pen — which laws like the US ESIGN Act and the EU's eIDAS accept for most private agreements. It is not a certificate-based digital signature: there is no cryptographic identity proof, which some government and financial workflows require. When in doubt, ask the receiving party what they accept.

Can the signature be removed from the PDF afterwards?

The signature is drawn into the page content, so casual viewers and printers see a permanently signed page. But like any visual signature — including a scanned wet signature — someone with a PDF editor could remove or copy it. That's a property of visual signatures generally, not of this tool.

Should I draw or upload my signature?

Drawing works well with a trackpad, touchscreen or stylus, and the pad trims the result to just the ink. If you already have a clean signature image, upload a PNG with a transparent background — it composes best over the page. A JPEG works too but brings its white rectangle along.
