Why does this say my browser isn't supported?

This tool relies on the native BarcodeDetector API, which is currently available in Chromium-based browsers like Chrome and Edge, but not yet in all browsers.

Is my image uploaded anywhere?

No — the image is processed entirely on your device using your browser's built-in scanning capability.

Can this read damaged or blurry QR codes?

Reading quality depends on the underlying browser API and the image's clarity — a sharp, well-lit photo scans much more reliably than a blurry one.

Can it read other barcode types, like a UPC barcode?

This tool is configured specifically for QR codes; other barcode formats are not currently read by this tool.

What happens if no QR code is found?

You'll see a clear message telling you no QR code was detected in the chosen image.

Does this work on mobile browsers?

It works wherever the BarcodeDetector API is supported, which includes Chrome on Android; iOS Safari support varies by version.

What Is a QR Code Reader?

A QR code reader scans an image containing a QR code and extracts the text or link it encodes. This tool uses your browser's own native barcode-detection capability (the BarcodeDetector API, available in Chromium-based browsers like Chrome and Edge) to read the code directly from an uploaded image.

Because it relies on a built-in browser feature rather than a third-party scanning library or a server upload, the image you choose is processed locally and is never sent anywhere — though it does mean the tool only works in browsers that support this API.
