Security & Architecture

At Free Signature Maker, we understand that the documents you need to sign—contracts, leases, legal forms—are sensitive. That is why we built our tool with a Security-First approach.

How Our Technology Works

Most e-signature tools work like this: You upload a file -> It travels to their server -> They save it -> You sign it -> You download it. This creates a risk of data breaches.

Our Tool works like this:

1. Local Loading: Your browser reads the file from your hard drive into your computer's RAM.
2. Canvas Rendering: We use HTML5 Canvas to display the image of the document.
3. Local Modification: When you draw, the JavaScript code running on your device overlays the ink pixels.
4. Instant Export: The browser bundles the data into a new PDF file and saves it. No network request is made.

SSL Encryption

Our entire website is served over HTTPS (Hypertext Transfer Protocol Secure). This ensures that the connection between your browser and our website is encrypted using 256-bit SSL. While we don't transfer your files, this encryption ensures that the code of our tool cannot be tampered with by third parties (like malicious WiFi hotspots).
