QR Generator
Convert any text or URL into a QR code directly in your browser.
You can customize the size in pixels, adjust foreground and background colors, and instantly preview the generated QR code on the screen.
Once generated, the QR code can be exported as a PNG image with a single click, making it suitable for documents, presentations, printed materials, or sharing links online.
All QR code generation is performed locally on your device.
No input text, URLs, or generated images are uploaded to any server, allowing you to create and download QR codes quickly and securely.
Your QR code will appear here after generating.
