A free QR code generator that keeps zero data
Most "free" QR code generators route your links through their own servers so they can track every scan, or they lock your codes behind an account that can expire. This one does the opposite. It is a static, permanent QR code generator that runs entirely in your browser. The moment you type, the code is built locally with JavaScript. Your data never touches a server, because there is no server in the loop. That is what we mean by zero-knowledge: the tool has zero knowledge of what you encode.
SQNCY builds privacy-first, security-governed software. This generator is a small, public demonstration of the same principle behind everything we ship: collect nothing, retain nothing, and prove it by design.
Frequently asked questions
Is this QR code generator really free?
Yes. No account, no sign-up, no watermark. The codes are yours to use anywhere, forever.
Do my QR codes expire?
No. These are static QR codes. The data is encoded directly into the pattern, so they work permanently and never depend on our servers. Unlike dynamic (redirect) QR codes, there is nothing that can expire or be switched off.
Is my data private?
Completely. Every code is generated inside your own browser. Nothing you type is uploaded, stored, logged, or tracked, and nothing is saved when you close the tab. The only thing the page sends is an anonymous tick for the public counter when you make a code, and it carries nothing you typed and nothing about you.
What is a zero-knowledge QR code generator?
It means the service has zero knowledge of your data. All processing is client-side, so the operator never receives, sees, or stores what you encode. This is client-side, zero-retention privacy, not a cryptographic zero-knowledge proof.
What types of QR codes can I create?
Links, plain text, Wi-Fi logins, contact cards (vCard), and pre-filled emails. Download each as a PNG or a scalable SVG.
