Gone are the days of printing a PDF just to sign it and scan it back. You can sign any PDF document online for free in seconds — no app download, no account registration, and completely legally binding in most jurisdictions.
This guide covers three signature methods, explains electronic signature legality, and gives you a step-by-step walkthrough for signing PDFs on any device.
3 Ways to Create Your Electronic Signature
✏️ Method 1: Draw Your Signature
Use your mouse, trackpad, or touch screen to draw your signature naturally. This produces the most authentic-looking result and closely matches your handwritten signature. Works great on mobile touchscreens.
Best for: Contracts, legal documents, anything requiring a personal signature feel.
⌨️ Method 2: Type Your Signature
Type your name and select a signature font (cursive, printed, etc.). Fast and consistent — ideal if you need to sign many documents with an identical-looking signature.
Best for: Internal documents, forms, approvals where exact signature style is less critical.
🖼️ Method 3: Upload Signature Image
Scan or photograph your handwritten signature on white paper, then upload it as a PNG (preferably with transparent background). This gives you a reusable, authentic-looking signature from a real pen.
Best for: Business contracts, legal agreements, documents where your exact signature is required.

Is an Electronic Signature Legally Valid?
Yes — in most countries, electronic signatures are legally recognized and binding. Key legislation includes:
- USA: ESIGN Act and UETA make electronic signatures legally equivalent to handwritten ones
- European Union: eIDAS Regulation defines standards for electronic signatures
- UK: Electronic Communications Act recognizes e-signatures
- Australia, Canada, India: All have equivalent electronic signature laws
For the highest level of legal recognition, use a qualified electronic signature (QES) provider. For most everyday documents — contracts, agreements, forms — a standard electronic signature as described here is fully sufficient.
