About the QR Code Scanner
strong long-tail opportunityThe QR Code Scanner is a free online tool designed to decode QR codes instantly using your device's camera or uploaded image files — all entirely in your browser. Whether you need to scan a QR code from a restaurant menu, decode a Wi-Fi QR code, verify a link before visiting it, or extract text from a saved QR image, this tool provides real-time scanning using the jsQR library with multi-scale contrast enhancement for reliable detection. To build a broader QR workflow, pair this with our QR Code Generator for creating codes, our Image Converter for processing scanned assets, or our Password Generator for credential-related workflows.
The scanner works in two modes: live camera scanning (using your rear-facing camera with auto-focus) and image upload. Click Start Camera to activate the live feed — the tool continuously scans each video frame and displays the decoded result as soon as a QR code is detected. Alternatively, upload a PNG, JPG, or other image file containing a QR code; the tool applies contrast enhancement and multi-scale analysis to maximize detection rates. All processing happens 100% client-side using jsQR — your camera feed and images never leave your device.

Frequently Asked Questions
Is my camera feed recorded?
No. The scanning process happens entirely in your browser's memory using the Canvas API and jsQR. No video or image data is ever sent to any server.
Why can't I access the camera?
Ensure you have granted camera permissions to this website in your browser settings. Also check that no other application (like a video call app) is currently using the camera.
What types of QR codes can be scanned?
The scanner works with standard QR codes (Model 1 and Model 2) containing URLs, plain text, Wi-Fi credentials, vCard contact data, email addresses, phone numbers, SMS payloads, and more.
Can I scan from an image file?
Yes. Click Upload Image and select a PNG, JPG, GIF, WebP, or BMP file containing a QR code. The tool applies multi-scale analysis and contrast enhancement to maximize detection.
Does it work offline?
Yes. Once the page is loaded, the jsQR library and all scanning logic run locally in your browser. However, you will need an internet connection to visit any URL that you scan.
Is it safe to scan any QR code?
The scanner reveals the decoded content before you act on it. If the result is a URL, it is displayed as a clickable link so you can verify the destination before visiting — helping protect you from malicious QR codes.
Why is the scanner not detecting my code?
Ensure the QR code is well-lit, in focus, and not obscured by glare or reflections. For camera scanning, hold your device steady about 6-10 inches away. For image uploads, try cropping the image closer to the QR code.
Can I scan barcodes?
This tool is optimized specifically for QR codes (2D matrix barcodes), not traditional linear 1D barcodes like UPC or EAN. For linear barcodes, a dedicated barcode scanner library would be needed.
