Lersi (lersi.xyz) is a pure, private, and performance-focused QR code generator created for people who just want things to work. Whether you're an individual sharing your WiFi, a teacher linking to lesson content, a business offering UPI payments, or an artist distributing your latest release — Lersi is here to help.
Lersi was created in response to the noise: too many tools add tracking, lock features, or demand logins. We stripped that away. What remains is speed, clarity, and simplicity. Your QR is generated instantly in your browser. Nothing is stored. Nothing is sent.
Every format we support was selected because it solves a real-world problem. From phone QR codes to Bitcoin payments, from location sharing to vCard contact exchange — Lersi is ready for all of it, any time, for free.
We don’t advertise. We don’t watermark. We don’t analyze behavior. We simply provide a full range of QR code tools to everyone, equally.
If your goal is to connect people, ideas, or resources with speed and precision — you're already using Lersi the right way. Welcome.
