How it works
- STEP 1
Draw the signature
Use a mouse, touchpad, stylus, or touchscreen to sign inside the canvas.
- STEP 2
Adjust the appearance
Choose a suitable pen colour and stroke width, then redraw if needed.
- STEP 3
Download the image
Save the signature and resize or compress it if the receiving portal has strict limits.
Common upload problems this solves
Portal requires a specific KB size
Create the signature first, then use Resize Signature to 10KB or 20KB.
Signature is too faint
Use a dark pen colour and a thicker stroke on a clean canvas.
Generated image is not accepted as a legal signature
An image of a signature is not the same as a certificate-based digital signature. Follow the recipient's signing rules.
Privacy and file handling
Signature drawing and image generation happen locally in the browser. The canvas data is not uploaded by this tool. The downloaded image remains on your device unless you later upload it to another service.
