Can I create a handwritten signature without a scanner?

Yes. Browser-based signature pads let you draw your signature using a mouse, trackpad, or touchscreen. The signature is converted to a transparent PNG that can be placed on any PDF.

How do I get a transparent background on my signature?

Signature pads that export as PNG with a transparent background automatically remove the background. The SignPDF tool uses a transparent canvas, so the exported signature has no white background.

Can I use my drawn signature on multiple documents?

Yes. Once you draw your signature, it appears as an element in the tool. You can reposition it on the current PDF or create a new signature image for each document.

How to Create a Handwritten Signature Online

July 26, 2026 · By SEDI Editorial Team · 5 min read

A handwritten signature created online looks more personal than a typed name. With a browser-based signature pad, you can draw your signature using a mouse, trackpad, or touchscreen and save it as a transparent PNG for use on PDFs.

How to draw a signature online

Open the signature pad, draw your signature using a mouse or finger, adjust the pen color if needed, and add it to your PDF. The signature becomes a draggable element that you can position anywhere on the page.

The signature pad uses HTML5 Canvas with smooth Bezier curve rendering. The strokes are captured as vector paths and rendered at the canvas resolution. When you confirm the signature, it is exported as a PNG image with a transparent background.

You can choose from multiple pen colors: black, blue, red, or teal. The undo button removes the last stroke if you make a mistake. The clear button resets the canvas completely.

Tips for a good handwritten signature

Use a stylus or your finger on a touchscreen for the most natural result. On a desktop, a mouse produces a usable signature but may look less smooth. Take your time and draw at a moderate speed.

Practice on the canvas before confirming. The signature pad does not limit how many times you can clear and redraw. Aim for a signature that matches your physical signature reasonably closely, since a consistent signature is easier to match for identity verification.
