Hey devs!
I recently launched a small tool called SignatureGenerator.me — a fast, free, privacy-first digital signature creator. It lets you draw or type your signature right in the browser and download it instantly, no sign-up or watermark involved.
Let me walk you through what it does, why I built it, and how it works under the hood.
🛠 Why I Built This
I needed to sign a PDF and was frustrated with the existing options:
- Bloated tools with popups and ads
- Forced account creation
- Watermarks unless you pay
- Server uploads of personal signatures (big no-no for privacy)
So I thought — why not build a minimal web app that runs 100% on the frontend? That’s how SignatureGenerator.me was born.
✨ Key Features
- Draw or Type your signature
- Choose from elegant, script-style fonts
- Download as a high-res PNG with transparent background
- All offline – nothing is stored or sent to a server
- Fully responsive (works great on touchscreens)
🧱 Tech Stack
The tool is built with:
- HTML Canvas API for drawing
- React for interactivity
- Tailwind CSS for styling
- Google Fonts for nice script typefaces
- FileSaver.js (or plain canvas export) for image download
Everything is rendered and processed client-side, so no backend at all. Your signature stays private.
🧪 Lessons Learned
Handling both mouse and touch inputs for canvas drawing is tricky I had to normalize events carefully.
Font rendering can vary across browsers, so I had to test a lot to make the typed signatures look polished.
Optimizing for mobile touch UX (clear button, draw sensitivity) made a big difference in usability.
