About the QR Code Generator

Generate a reusable QR image for a web link, text or event details. Customize colors, pixel size, error correction and quiet-zone margin.

Formula or method

The browser creates a QR matrix and exports PNG or vector SVG. High contrast and empty margins improve scanning.

Worked example

Enter a website URL, choose 512 pixels, then download the PNG to add to a poster.

How to use the tool

Start with the example values above, then replace each input with your own figures. The results update immediately. Review the units, denominators, and assumptions before using any number in an important decision.

Assumptions and limitations

Test the printed code with several phone cameras. A QR code is not a URL-shortening service and the destination must remain accessible.

Frequently asked questions

Can I print this QR code?

Yes. SVG is recommended for scalable printing; test its contrast and scan performance.
