如何使用 二维码扫描器
Upload or drag in any image that contains a QR code and the scanner will decode the payload directly in your browser. It is ideal for screenshots, photographed menus, event tickets, Wi-Fi posters, and saved QR assets when you do not want to reach for your phone camera. If the result is a web link, you can open it instantly or copy the raw decoded text.
1
Upload the QR image
Drop a PNG, JPG, WebP, or similar image file into the scanner or click to browse.
2
Let the decoder analyze it
The tool reads the image locally and attempts multiple scan passes to find a QR pattern.
3
Review the decoded payload
Once found, the QR contents appear in plain text, including URLs, Wi-Fi strings, or raw text.
4
Copy or open the result
Copy the text for later use, or open it immediately if the payload is a supported link.
常见问题
Does this work with screenshots?+
Yes. Clean screenshots usually scan very well, as long as the QR code is not cropped too tightly or blurred.
Do my images get uploaded?+
No. The scan runs inside your browser, so your image stays on your device.
