Draw a signature and save it as a PNG
Sign with your mouse, finger or stylus and download a clean signature image — transparent PNG for dropping onto documents, or white background for forms. Smooth strokes, undo, ink colors, nothing uploaded.
How it works
- Draw your signature on the pad — mouse, finger or stylus all work.
- Adjust pen color and thickness; use Undo to fix a stroke.
- Download as PNG — transparent by default, or tick white background.
Questions about this tool
How do I put this signature on a PDF or document?
Download the transparent PNG, then insert it as an image in Word, Google Docs, or your PDF editor and place it on the signature line. The transparent background makes it sit naturally on any page.
Is a drawn signature legally valid?
In many situations and countries, yes — most e-signature laws accept an image of your signature for everyday documents. For high-stakes contracts, check what the receiving party requires; this tool creates the image, not a certified e-signature.
Why does my signature look smooth here?
Strokes are rendered with curve smoothing and high-DPI scaling, so the exported PNG is crisp even when drawn with a fingertip on a phone.
Is my signature uploaded or stored?
No — it exists only in your browser while you draw and in the PNG you download. Close the tab and it's gone, which is exactly what you want for something as personal as a signature.
