About SignPNG

Security-first tools for the modern professional.

Our Mission

SignPNG was born out of a simple observation: most "free" online tools are not actually free—you pay with your data. When it comes to something as sensitive as your handwritten signature, uploading it to a random server is a massive security risk.

Our mission is to provide professional-grade document tools that respect user privacy by design. By utilizing modern browser capabilities, we've built a system that processes your biometric data (your signature) entirely on your own device.

Who We Are

We are a small team of software engineers and security enthusiasts dedicated to building "Local-First" web applications. With years of experience in web cryptography and image processing, we've optimized SignPNG to be fast, lightweight, and above all, secure.

Our team believes that the future of the web is decentralized and private. SignPNG is our contribution to a safer digital ecosystem where users retain 100% control over their digital assets.
