How to sign a document on your iPhone

A form arrives that needs your signature. Rather than print, sign and scan it, you can sign it on your iPhone: scan the paper (or import the PDF), draw your signature once, and place it on the page.

This is a ScanMojo Pro tool: $39.99 a year with a 7-day free trial, or $6.99 a month (U.S. prices). Scanning and PDF export stay free.

  1. 1

    Get the document into ScanMojo

    Scan the paper form, or import the PDF from Files with Tools › Import a file.

  2. 2

    Open Tools › Sign

    Choose the document. Draw your signature with your finger; it's saved for next time.

  3. 3

    Place and size it

    Drag the signature onto the line, and drag its corner to resize it. Add text, like the date or your printed name, where the form asks for it.

  4. 4

    Share the signed PDF

    Tap Share › PDF and send it back.

A signature that looks like yours

Sign slowly with a fingertip, larger than you'd sign on paper. The signature is scaled down on the page, so a bigger drawing comes out smoother.

Is it legally binding?

Many everyday agreements accept a signature added this way, but some documents require a certified e-signature service or wet ink. If you're unsure, ask whoever sent you the document.
