How to Digitally Sign a Scanned Document on Android Privately
Sign contracts, lease agreements, and tax forms on your phone without printing, physically signing, and re-scanning.
To digitally sign a document on Android: 1) Open the document in ScanOrbit and select Sign. 2) Draw your signature on screen, pick an elegant calligraphy style, or scan physical ink on paper. 3) Position and scale the signature on the contract. 4) Save the signed PDF.
1. Draw or Scan Your Ink Signature
Use your fingertip or stylus on the touch canvas, or point your camera at a signature on blank paper to extract transparent vector ink.
2. Position & Stamp on Contract
Drag the signature to the signee block, pinch to scale, and optionally add an ISO date stamp.
3. Flatten & Export Securely
ScanOrbit flattens the vector signature layer into the PDF canvas so it cannot be extracted or tampered with.
