QR Code Decoder is a free browser-based toolkit for decoding, scanning, and creating QR codes.

Decode QR codes from uploaded images and screenshots, paste images directly from your clipboard, or scan codes using your device camera. The decoder can recognize common structured content including URLs, Wi-Fi networks, contact details, email, SMS, phone numbers, locations, and calendar events.

The built-in QR Code Generator lets you create custom QR codes for URLs, text, Wi-Fi, email, phone, SMS, locations, contacts, and calendar events. Customize colors, gradients, module and eye styles, frames, labels, and logos, then export your QR code as SVG, PNG, WEBP, or JPEG.

QR images, decoded content, and uploaded logos are processed locally in your browser rather than being sent to a QR processing server. No account or software installation is required.

The site also includes barcode decoding and scanning tools for common barcode formats.
