Simple signatures vs digital signatures

This tool makes a simple electronic signature: an image of your signature placed on the page. In the US, the ESIGN Act (15 U.S.C. §7001) says a signature may not be denied legal effect solely because it is electronic, and many everyday documents are signed this way. Whether a particular recipient accepts it is up to them.

A digital signature is different: it uses a certificate to seal the file so any later change is detectable. This tool does not create certificate signatures.

Some documents must be signed in ink. USCIS, for example, requires a handwritten signature on paper and PDF-upload filings; for those, print, sign, then scan.

Steps

  1. Add the PDF.
  2. Draw, type or upload a signature (or use one saved on this device).
  3. Click the page where it goes; resize it.
  4. Download the signed PDF.

Limits, stated plainly

  • No certificate-based (digital) signatures.
  • Typed signatures use a cursive-style system font if your device has one, otherwise a serif italic.
Already have Preview or Edge? Preview on a Mac (Markup → Sign) and the iPhone’s Markup can place a signature, and Edge’s viewer lets you draw one.
