解码 any QR code — upload an 图片 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 图片 — 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 图片 file, or use your camera to scan a code live. Decoding happens locally in your browser with jsQR, so the 图片 never leaves your device.
使用方法 scan a QR code
- Click 上传 Image and pick a screenshot or photo of a QR code.
- Or click Use Camera and point it at any QR code.
- The decoded content appears instantly — copy it with one click.
Frequently asked questions

Is QR scanning private?
Absolutely. The 图片 is decoded locally in your browser and never uploaded anywhere.
What can a QR code contain?
Almost anything: URLs, WiFi credentials, text, email addresses, phone numbers, and calendar events.
Why does my scan fail?
Blurry, damaged, or low-contrast codes fail to decode. Try a sharper 图片 or scan under better lighting.
