QR Code Generator
Generate a downloadable QR code from any text or URL, with adjustable size and error correction.
QR codes pack a URL, a bit of text, or structured data like a Wi-Fi network's credentials into a scannable square pattern that any modern phone camera can read instantly — no app required. They've become a standard way to bridge printed material and physical spaces to a digital destination, from restaurant menus to event tickets to product packaging.
This generator creates a real QR code from any text or URL you enter, rendered instantly in your browser and downloadable as a PNG. You can adjust the pixel size for different use cases (small for a business card, large for a poster) and the error correction level, which controls how much of the code can be damaged or obscured (for example, by a logo placed in the center) while still scanning correctly — higher error correction adds redundancy at the cost of a visually denser code.
Everything happens client-side using a standard QR encoding library, so the content you enter is never transmitted anywhere.

Frequently asked questions
Common mistakes to avoid
- Using low error correction when planning to overlay a logo, resulting in a code that fails to scan.
- Generating a QR code too small for its intended print size, making it hard for cameras to focus on and scan.
