Step-by-Step Guide: How to Sign a PDF Digitally

Signing a PDF does not require you to print the document, sign it with a pen, and scan it back. You can sign any PDF electronically in seconds using your mouse, trackpad, or touchscreen.

Step 1: Open the Sign PDF Tool

Navigate to our free Sign PDF Tool. The application loads entirely in your browser and works 100% offline once opened.

Step 2: Choose Your PDF File

Drag and drop your PDF document into the browser window or select it from your device. Because PrivaPDF runs client-side, your document is never uploaded to a server.

Step 3: Create and Place Your Signature

Choose between drawing your signature using a mouse/touchpad, typing your name with elegant calligraphy fonts, or uploading an image of your physical signature. Place and resize it anywhere on the document.

Step 4: Save and Download

Click "Download" to generate the signed PDF. The signature is flattened directly into the PDF structure, ensuring it cannot be easily edited or removed.

Common questions

How do I sign a PDF online for free?

With PrivaPDF, you can draw or type your signature and place it on any page. Everything is done locally in your browser, so your files are never uploaded.

Is my signature legally binding?

Yes, electronic signatures are legally valid for most business and personal agreements in the US (ESIGN Act) and EU (eIDAS).

Do I need to print the document to sign it?

No. Printing, signing by hand, and scanning is outdated. Modern electronic signatures let you sign digital documents on screen.

Is my file uploaded to a server?

No. All processing happens entirely in your browser using WebAssembly. Your file never leaves your device.
