How to Sign a PDF Online Without Printing

Gone are the days of printing a PDF, signing it by hand, and scanning it back. Today you can sign any PDF document directly in your browser in under a minute. Here's how to add a professional electronic signature to your PDFs for free.

How to Sign a PDF with ProPDF

1. Open the Sign PDF tool and upload the document you need to sign.
2. Create your signature: draw it with your mouse or finger, or type it and choose a handwriting font.
3. Click on the page where you want to place your signature, then drag to position and resize it.
4. Add your signature to as many pages as needed, then download the signed document.

Draw vs. Type Your Signature

ProPDF offers two ways to create your signature. Drawing lets you create a natural-looking signature using your mouse, trackpad, or touchscreen. This is closest to your real handwriting. Typing lets you enter your name and choose from several handwriting-style fonts for a clean, consistent look.

Both methods produce a professional result. You can save multiple signatures to your library for quick reuse across documents.

Is an Electronic Signature Legal?

Electronic signatures are legally recognized in most countries. In the US, the ESIGN Act and UETA make electronic signatures as legally binding as handwritten ones for most documents. In the EU, the eIDAS regulation provides a similar framework. For high-value contracts, regulated industries, or government documents, consult your legal advisor about specific requirements.

Your Signature Stays Private

With ProPDF, your signature is created and applied entirely in your browser. It's never uploaded to any server. This means you can sign confidential contracts, NDAs, and personal documents with complete privacy.
