Why ScannerQR is private
Most online scanners upload your image to a server to decode it. ScannerQR doesn't. Everything happens locally in your browser, so sensitive QR codes — Wi-Fi passwords, boarding passes, payment addresses — stay completely under your control.
Browser-only processing
Decoding happens on your device using WebAssembly. Your CPU does the work, not our servers.
No image uploads
Photos, screenshots and PDFs are never sent over the network. They never leave your device.
No stored scans
Scan history lives in your browser only. We have no database of what you scan.
No accounts required
No email, no login, no tracking profile. Just open the page and scan.
