Instant Browser-Based Scanning

Most scanner apps require downloads or upload your images to remote servers. Our tool uses the HTML5-QRCode library to convert QR code data directly on your device. Whether you're scanning a restaurant menu or decoding a saved WiFi QR image, the processing happens inside your browser, ensuring your data remains private and secure.

How to Scan & Decode

1. Select Input Method

Choose 'Scan with Camera' for real-time detection or 'Upload Image' to convert QR code files from your device.

For desktop users, dragging and dropping an image file is often faster.

2. Align or Upload

Point your camera at the code or upload your file. Our smart engine auto-selects the rear camera for better focus.

Ensure good lighting; shadows can interfere with the matrix detection.

3. Access Content

The decoded text or URL appears instantly. Copy it to your clipboard or open links with a single click.
