How to Sign PDF Documents Electronically for Free

Gone are the days of printing a PDF, signing it by hand, scanning it back, and emailing the result. Electronic signatures let you sign any PDF document in seconds, directly from your browser. This guide walks you through the entire process.

Why Use Electronic Signatures?

Electronic signatures have become the standard for signing documents quickly and securely. Here is why they matter:

• Save time — sign documents instantly without printing or scanning
• Work remotely — sign from anywhere on any device with a browser
• Reduce paper waste — go completely paperless for routine agreements
• Legally recognized — e-signatures are legally binding in most countries under laws like ESIGN and eIDAS

Types of Electronic Signatures

1. Drawn Signature

Use your mouse, trackpad, or touchscreen to draw your signature directly on the PDF. This creates a natural, handwritten look that closely resembles a pen-on-paper signature.

2. Typed Signature

Type your name and choose from a selection of handwriting-style fonts. This is the fastest method and works well for informal agreements and internal documents.

3. Uploaded Signature

If you already have a signature image saved as a PNG or JPG, you can upload it and place it anywhere on your PDF. This is ideal if you have a professionally scanned signature.

Tips for a Professional Signature

• Use a stylus or finger on mobile — touchscreens give you better control for a natural-looking drawn signature
• Keep it consistent — use the same signature style across all your documents for credibility
• Add the date — many agreements require both a signature and a date, so include both
• Check placement — make sure your signature sits within the designated signing area
