Scan QR Code
デコード any QR code — upload an 画像 or scan with your camera. Private, instant, and free.
What is a QR code scanner?
A QR code scanner decodes the information hidden inside any QR 画像 — a website address, WiFi credentials, a phone number, or plain text. It is the fastest way to read a code from a screenshot, a poster, a business card, or the screen of another device.
This scanner works two ways: upload a QR 画像 file, or use your camera to scan a code live. Decoding happens locally in your browser with jsQR, so the 画像 never leaves your device.
