Ultrafast Qrcode is a pure frontend tool that allows you to quickly encode text into QR codes or decode QR code images. It's built with vanilla HTML, CSS, and JavaScript, making it fast, lightweight, and privacy-friendly since all processing happens locally in your browser.
To encode text to QR code: Simply type your text in the input field above, and the QR code will be generated instantly. You can then right-click on the QR code to save it as an image.
To decode QR code: drag and drop a QR code image onto the QR code area, or paste it from your clipboard, or just click the qrcode image to load a file locally. The decoded text will appear in the input field automatically.
