Digital Signature Generator
Draw your signature with mouse or finger and download a transparent PNG — no upload, no watermark.
Draw with mouse, trackpad, or finger. Export is a transparent PNG at 900×300.
About This Tool & Technical Logic
Draw your signature directly on the canvas with a mouse, trackpad, or finger, then download it as a transparent PNG ready to place on documents, contracts, and email templates.
The canvas records strokes with pressure-simulated smoothing and exports at 3× resolution so signatures stay crisp when scaled into PDFs. Because everything is local, your signature never leaves the device — important, since a signature image is a credential.
HTML5 canvas pointer events → smoothed paths → toDataURL("image/png") at export scale.
How to Use — Step by Step
- 1
Sign large and slow
Big, unhurried strokes produce cleaner downscaled PNGs than small cramped ones.
- 2
Adjust pen thickness if needed
Thicker strokes survive shrinking and printing better than hairlines.
- 3
Download the transparent PNG
Drop it onto PDFs with our watermark/signature tools or paste into email signatures.
