What is Signature Generator?
Digital signatures are needed for documents, emails, contracts, and forms in the increasingly paperless workplace. DailyDevTools' Signature Generator provides a smooth canvas where you draw your signature with a mouse, trackpad, or touchscreen — then download it as a transparent PNG, SVG, or JPEG. No plugins, no accounts, and your signature image never touches any server.

- 2Use the pen size slider to adjust stroke width, and pick a pen color (black, blue, or custom)
- 3Click Clear to start over, or Undo to remove the last stroke
- 4Click Download PNG to save your signature with a transparent background, ready to overlay on documents
