Signature Sketch is a free handwritten signature generator that creates transparent PNG signatures entirely in your browser without requiring any sign-up or data upload.
What is Signature Sketch?
Signature Sketch is a web-based tool that lets you create digital handwritten signatures by drawing with your mouse, trackpad, or finger, or by typing your name and selecting a handwriting font style. It outputs transparent PNG images or PDFs ready for use in Word, Google Docs, and email. The tool runs completely locally on your device—no data ever leaves your browser.
Key Features
