Make a clean signature in seconds

A signature image is handy for invoices, letters, email footers and quick approvals. This tool gives you a crisp, transparent PNG, cropped tight to the ink so it drops neatly into any document. Draw it for a personal touch, or type your name in one of four handwriting styles for a neat, consistent look.

Tips for a good-looking signature

  • Draw large and slowly. The image is cropped and can be scaled down, so a big signature stays sharp.
  • Use a stylus or finger on a phone or tablet for the most natural strokes; turn your phone sideways for more room.
  • Blue ink makes it obvious a document was signed, which some people prefer for printed copies.

Sign your documents

OZO's invoice generator, quote generator and timesheet generator include a signature field, so you can sign directly as you create the document.

Frequently asked questions

Is a drawn signature image legally binding?

In many countries an electronic signature can be valid for everyday agreements, but laws differ, and some documents (wills, property deeds, certain contracts) need a handwritten or certified digital signature. If in doubt, check the rules for your document and country.

Is my signature uploaded anywhere?

No. It is drawn and saved entirely in your browser, and the PNG goes straight to your device. OZO never sees it.

Why does the download have a transparent background?

So the signature sits naturally on any document, letterhead or coloured background, just like ink on paper.

How do I sign a PDF with this?

Download the PNG, then insert it as an image in your PDF editor, word processor or e-signing app. On OZO’s invoice, quote and other document tools you can draw or upload a signature directly.
