QR Code Decoder

Simply upload your QR code image by clicking the upload area or dragging and dropping the file. Our tool will automatically detect and decode the QR code, displaying the content immediately. Supported formats include JPG, PNG, GIF, and WebP. You can also try the "Demo Content" button to see sample decoded content.

Yes! Click the "Use Camera" button and our tool will guide you through granting camera permission. When prompted by your browser, click "Allow" to enable camera access. Position the QR code within the overlay frame, and our tool will automatically detect and decode it in real-time. The tool works on both desktop and mobile devices.

If you denied camera permission, you can re-enable it: In Chrome/Edge, click the camera icon in the address bar and select "Allow". In Firefox, click the shield icon and allow camera access. In Safari, go to Safari → Settings → Websites → Camera and allow access for this site. After changing settings, refresh the page and try the camera feature again.

Our decoder supports all standard QR code formats including plain text, URLs, email addresses, phone numbers, SMS messages, WiFi credentials, contact information (vCard), calendar events, and more. It automatically detects the content type and formats it appropriately.

QR codes have built-in error correction that allows decoding even when partially damaged or blurry. Our tool can often recover data from low-quality images through advanced image processing and error correction algorithms. For best results, ensure good lighting and focus when capturing QR codes.

No, all QR code processing happens locally in your browser. Your images and decoded content never leave your device. This ensures complete privacy and security for sensitive information like WiFi passwords, contact details, or personal data.

Yes! You can copy the decoded content to your clipboard, download it as a text file, or share it directly with other applications using your device's native sharing features. The tool also formats different content types appropriately for easy use.

Our tool provides detailed analysis including QR code version, module count, error correction level, data encoding format, character encoding, and content type. This information is useful for developers, quality testing, and understanding QR code properties and capabilities.

Common issues include poor image quality, insufficient lighting, perspective distortion, or heavily damaged QR codes. Try improving image quality, ensuring good contrast, capturing from a different angle, or using better lighting. Some severely damaged codes may be unrecoverable even with error correction.

Yes, our QR code decoder is fully responsive and works perfectly on mobile devices, tablets, and desktops. The camera functionality is optimized for mobile use, allowing you to scan QR codes directly with your phone's camera in real-time.

Currently, our tool processes one QR code at a time for optimal accuracy and performance. If your image contains multiple QR codes, it will detect and decode the most prominent one. For batch processing, upload each QR code image individually.

Our decoder supports all common image formats including JPG/JPEG, PNG, GIF, WebP, and BMP. The tool automatically handles different color depths, resolutions, and compression levels to extract QR codes from various image sources.

Our QR code decoder uses advanced computer vision algorithms with high accuracy rates for properly formatted QR codes. The success rate depends on image quality, lighting conditions, and QR code condition. Clear, well-lit images with minimal distortion achieve near 100% accuracy.

Yes, our QR code decoder is completely free with no hidden fees, registration requirements, or usage limits. You can decode unlimited QR codes, use camera scanning, analyze technical properties, and export results without any charges.

Yes, our decoder supports full UTF-8 character encoding, allowing it to decode QR codes containing special characters, emojis, international text, and symbols. The tool properly handles different character sets and displays them correctly in the decoded output.
