The Death of the Print-Sign-Scan Routine

Printing out an eight-page agreement, signing the last sheet with a pen, taking a smartphone photo, and converting it back into a PDF is slow, wasteful, and produces degraded, crooked documents. Modern electronic signatures provide full legal validity under the US ESIGN Act, UK eIDAS, and EU regulations.

Types of Signatures Supported on OMNIKITY

* **Drawn Signatures:** Use your mouse or touchscreen to draw a natural signature.
  • **Typed Signatures:** Type your legal name and choose from elegant cursive calligraphic styles.
  • * **Uploaded Stamp or Signature PNG:** Place a pre-scanned transparent image of your physical signature directly onto the exact signing line.
