About Signature Generator

Signature Generator is a free, private tool by Digital Heroes that runs entirely in your browser. Choose Draw mode to sketch a natural, pressure-sensitive signature with your mouse or touchscreen, or switch to Type mode to render your name in one of six cursive font styles. When you are done, export a trimmed transparent PNG at any resolution up to 2000 px wide, ready to drop into a PDF, Word document, or email footer. Because everything happens locally, your signature data is never uploaded to a server. No account, no installation, no usage limits.

What you can do

Draw a natural signature with velocity-sensitive strokes that thicken and thin like a real pen, on any device with a mouse or touchscreen.

Type your name in 6 cursive styles, including Flow, Script, Classic, Elegant, Casual, and Hand, with an instant live preview.

Choose your ink color from black, blue, green, red, or any custom color, shared across both Draw and Type modes.

Export a trimmed transparent PNG with no background, sized from 300 to 2000 px wide, ready for PDFs, Word docs, and design tools.

Download a white-background PNG for platforms that do not support transparency.

Copy the signature image straight to your clipboard for quick pasting into documents or email clients.
