How to make a signature image

  1. Draw your signature with a mouse, finger or pen, type your name, or choose a photo of your signature on paper.
  2. Choose the ink color and line thickness.
  3. Download it as a transparent PNG, an SVG or a JPG.

Three ways

  • Draw: smooth lines, with Undo. Drawn signatures can also be saved as a real vector SVG.
  • Type: your name in a handwriting style.
  • Clean up a photo: the paper is made transparent and the ink kept, in its own color or recolored black or blue.

Good to know

  • A transparent PNG sits on the page without a white box: use it in Word, Google Docs, emails and image editors.
  • To sign a PDF directly, use Sign PDF.
  • This is a picture of your signature (an electronic signature), not a certificate-based digital signature.

常见问题

Is my signature saved anywhere?

No. It exists only in this page until you download it, and it is never uploaded.
