Draw your signature online (transparent PNG)
Draw your signature with a mouse, a trackpad or your finger on mobile, then download it as a PNG image with a transparent background, ready to insert into a document.
How it works
The canvas captures your mouse, trackpad or finger movements (on a touchscreen) to draw a continuous stroke, just like a pen on paper. The background stays transparent: only the drawn stroke is kept on export.
Can I sign with my finger on a phone or tablet?
Yes, the drawing area responds to touch events as well as to the mouse; on a smartphone or tablet, sign directly with your finger or a compatible stylus for a more precise, natural stroke.
Does the downloaded file really keep a transparent background?
Yes, the PNG format preserves transparency: only the ink of your signature is visible, so you can overlay it cleanly on an existing document without an unsightly white box around it.
The drawing stays entirely local to your browser: no signature is sent to or saved on a server.
