Qr Code Generator

What is a Qr Code Generator?

QR codes connect print and the physical world to digital content: a poster linking to an event page, a menu on a restaurant table, a business card leading to a portfolio or a product label opening a manual. This generator creates a QR code from any URL or text, with custom colours, and lets you download it for print or web.

How to use it

  1. Enter the URL or text.
  2. Choose foreground and background colours and the error correction level if available.
  3. Download the image and test it with your phone camera before printing.

Error correction levels

QR codes contain redundancy that lets them be read even when partly damaged or covered:

  • L: about 7% recoverable, smallest code.
  • M: about 15%, a good default.
  • Q: about 25%.
  • H: about 30%, needed if you place a logo in the centre.

Design and print rules

  • Contrast: keep a dark code on a light background. Inverted or low-contrast colours fail on many scanners.
  • Quiet zone: leave a blank margin of about four modules around the code.
  • Size: at least 2 × 2 cm for close scanning; scale up with distance, roughly 1 cm per 10 cm of scanning distance.
  • Shorter data makes a less dense, easier-to-scan code. Use short URLs for printed codes.
  • Use SVG or a high-resolution PNG for print so edges stay sharp.

Static codes do not expire

The content is encoded directly in the pattern, so this code works forever and does not depend on a tracking service. If you might need to change the destination later, encode a URL you control and redirect it as needed.

Frequently Asked Questions

Do these QR codes expire?

No. The data is stored in the code itself, so it keeps working as long as the destination exists.

Can I put a logo in the middle of a QR code?

Yes, if you use high error correction and keep the logo small, then test the code thoroughly.

Why won't my coloured QR code scan?

Low contrast or inverted colours confuse scanners. Use a dark code on a light background.

How big should a printed QR code be?

At least about 2 by 2 cm for close range, larger for scanning from a distance.
