About This Tool
QR Code Reader decodes a QR symbol from an uploaded image using the browser’s supported detection capability and displays its text or link payload for copying.

Practical Use Cases
Saved-code inspection
Read a QR code from a screenshot without using another device.
Link verification
Inspect the encoded destination before deciding whether to visit it.
Privacy and File Processing
QR Reader keeps its Browser-decodable image containing a QR code input in browser memory while the operation runs. The workflow creates Decoded text or URL for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.
Supported Inputs and Outputs
Input
- Browser-decodable image containing a QR code
Output
- Decoded text or URL
Quality and Fidelity
Decoding is binary: a clear supported symbol yields payload text, while blur, glare, perspective, cropping, or insufficient contrast can prevent detection.
Limitations and Important Notes
- Requires browser BarcodeDetector support for QR codes.
- Damaged or partially cropped symbols may fail.
- Decoded URLs are untrusted input and should be reviewed before opening.
Worked Example
Use a representative source image, apply Qr Reader, and compare the result with the original at full size before publishing it.
Helpful Tips
- Keep the untouched source image while evaluating Qr Reader.
- Check the Decoded text or URL result at its intended display size.
Frequently Asked Questions

No. Qr Reader creates a result or extracted value without overwriting the selected source.
What affects Qr Reader results?
Decoding is binary: a clear supported symbol yields payload text, while blur, glare, perspective, cropping, or insufficient contrast can prevent detection.
Can a very large image fail in Qr Reader?
Yes. Qr Reader remains subject to browser decoding, canvas, model, and memory limits.
