How do I sign documents from my phone?
Open the document in any e-signature app (iContract, DocuSign, Adobe Sign) on your phone's browser or native app, draw your signature with your finger, place it on the signature field, and tap done. The signed PDF is emailed instantly.
Signing documents on your phone takes 60 seconds:
From an emailed signing link: 1. Tap the 'Sign Document' link in the email. 2. The document opens in your mobile browser (no app needed). 3. Tap each signature field, draw your signature with your finger. 4. Tap 'Submit' or 'Finish.' Done.
To sign your own PDF on phone: 1. Open iContract.pro/sign-free in your phone browser. 2. Tap 'Upload PDF' and select from your files or photos. 3. Place signature field, draw with finger, download or share.
iOS specific: in Apple Mail and Files, you can use the Markup tool to add signatures to PDFs natively. Tap the markup icon, then the signature button.
Android: Adobe Acrobat Reader (free) and iContract both support full mobile signing.
- Use a stylus for cleaner signatures.
- Save your signature image once, reuse it.
- Enable Face ID / fingerprint for faster authentication.
- iContract supports Face ID/Touch ID login for native app users.
Legal validity is identical to desktop — phone-signed documents are fully ESIGN/eIDAS compliant. The audit trail captures the same data: IP, timestamp, signer email.
Most modern e-signature platforms are 'mobile-first' — designed to work flawlessly on a 5-inch screen.
