QR Visualizer is a frontend-only educational app for visualizing QR code decoding. Uploaded images and camera captures are processed locally in your browser.

Uploaded images

When you upload an image, the image is decoded in the browser by the app. QR Visualizer does not upload the image to a server for processing.

Camera access

Camera permission is requested only when you choose the Take Photo action. The captured image is used locally to run the QR decoding walkthrough.

Decoded content

The final decoded text or URL is shown in the app. Opening a decoded URL leaves QR Visualizer and follows that external link in your browser.

Limitations

QR Visualizer is an educational visualization tool. It is not a security scanner and does not verify that decoded links are safe.
