What Is a QR Code and When to Use One

A QR code (Quick Response code) is a two-dimensional barcode that can store URLs, plain text, contact details, or other data. When someone scans it with a phone camera or a QR reader app, they are taken to the link or see the stored information. QR codes are useful for business cards, menus, posters, product packaging, event check-in, and payment links.

Best Practices for QR Codes

Use a short, stable URL so the QR code stays valid if you change your site structure. Test the code on several devices before printing. For print, choose a size that is easy to scan from a typical distance (often at least 2 cm by 2 cm). Avoid placing QR codes where they can be damaged or obscured. For branding, you can match the foreground colour to your brand, but keep enough contrast for reliable scanning.

Frequently Asked Questions

Are QR codes free to use? Yes. QR codes are an open technology. This generator creates them for free with no sign-up.

Can I use a QR code for a PDF or image? This tool encodes text or URLs. To link to a PDF or image, upload the file to your website or cloud storage and use that URL as the QR content.

Do QR codes expire? The code image does not expire. If the content is a URL and you later change or remove that page, the link will break. Use a permanent URL when possible.

What size should my QR code be for printing? For flyers or business cards, 2 cm by 2 cm or larger is usually enough. For posters or signs, use a larger size so people can scan from a distance.
