Decode QR Codes from Images
QR Code Decoder extracts data from QR code images without requiring any app installation. Upload JPG, PNG, or other image formats to instantly read URLs, contact details, WiFi passwords, or any encoded information. All processing happens in your browser.
Privacy-Focused QR Scanning
Unlike mobile apps that upload your scans, this decoder processes images locally using WebAssembly-powered jsQR. Your photos, screenshots, or downloaded QR codes never leave your device. Perfect for scanning sensitive QR codes like crypto wallets, API keys, or private URLs.
Frequently Asked Questions

QR Code Decoder supports PNG, JPG, JPEG, GIF, and WebP formats. Upload images from your device or drag-and-drop. For best results use high-resolution images with clear contrast between the QR code and background.

QR codes can encode URLs, plain text, contact information (vCard), WiFi credentials, phone numbers, email addresses, and calendar events. The decoder automatically detects the content type and displays the decoded information clearly.
