How to Sign a PDF Electronically (Free)

Printing a document just to sign and re-scan it is wasteful and slow. An electronic signature placed directly on the PDF is faster and looks cleaner.

Three ways to sign

• Type — your name in a signature-style font. Fastest for low-stakes forms.
• Draw — sign with a trackpad/touchscreen for a real handwritten look.
• Upload — a transparent PNG of your signature (sign on white paper, photograph, remove background once, reuse).

How to sign a PDF step by step

1. Open Sign PDF and select the document.
2. Create your signature (type, draw, or upload).
3. Drag it onto the signature line; resize to fit. Add a date or initials if needed.
4. Download the signed PDF.

Tips

• Make a reusable PNG of your signature once — every future signing becomes 10 seconds.
• Place, don’t cover — position on the line, not over text.
• Flatten if needed: to stop the signature being moved later, flatten the PDF after signing.

Is an electronic signature valid?

For most everyday agreements, a clear electronic signature is widely accepted. For high-stakes legal/regulated documents, check whether a qualified/digital signature is specifically required.
