When should I sign a PDF?

- You are away from a printer and scanner.
A PDF tool that respects your privacy
Many online signing services upload your document and signature to a server. This one works inside your browser, so confidential files never leave your device.
Tips for better results
- Draw with a stylus or your finger on a touch screen for a more natural signature.
- When uploading a photo, sign on plain white paper in good light so the background is removed cleanly.
- A visual signature is not a certificate-based digital signature. Confirm that the recipient accepts it.
- Protect the signed file with a password using Protect PDF before you share it.
Sign PDF is free, works on phones, tablets and computers, and needs no registration.
