Windows doesn't have a built-in PDF signing tool as polished as Mac's Preview, but there are several solid free options — including one that's already installed on your computer.
Method 1: Microsoft Edge (Already Installed on Windows 10/11)
- 1Right-click your PDF → 'Open with' → Microsoft Edge
- 2Click the Draw tool (pencil icon) in the top toolbar
- 3Draw your signature directly on the document
- 4Click the Save icon (or press Ctrl+S) to save
Edge's draw tool creates a free-form ink overlay. It's quick but the output is an image annotation rather than a proper signature field — fine for most uses.
Method 2: Browser-Based Tool (Best Quality + Privacy)
For a cleaner result — especially if you need to add a typed signature, date field, or text annotations alongside your signature — use Signpdf in your browser.
- 1Open Chrome, Edge, or Firefox and launch Signpdf
- 2Click 'Sign PDF' and upload or drag your document
- 3Choose Draw (mouse), Type (font-based), or Upload (PNG/JPG image)
- 4Position and resize your signature
- 5Download the finished PDF
The browser-based method works on any Windows version and any browser. Your file is processed locally — it's never sent to a server.
Method 3: Adobe Acrobat Reader (Free Tier)
The free version of Adobe Acrobat Reader for Windows includes basic e-signing. Download it from Adobe's site, open your PDF, and use Tools → Fill & Sign. You'll need a free Adobe account.
