Expert advice from Security Specialists
For the most natural-looking signature, use a tablet or smartphone touchscreen to draw your signature with your finger.
If uploading a signature image, use a PNG with a transparent background so it doesn't block text lines.
You can add multiple signatures (e.g., yours and a witness's) or initials to different pages before saving.
Use the text tool to add the current date or your printed name alongside your signature for completeness.
