## Why QR codes work

A QR code turns a print surface into a tap-free link to anything digital — a website, menu, payment page, or WhatsApp chat. They're cheap, universal, and scannable by any modern phone camera. The free [QR Code Generator](https://www.pyalm.com/free-tools/qr-code-generator) creates high-resolution codes you can download and print.

## Static vs dynamic

A **static** QR encodes its content directly, so it never expires and needs no third-party service — perfect for a fixed URL or text. A **dynamic** QR points to a redirect you can change later and track. Our generator creates static codes that keep working forever.

## Where to use them

- Menus, packaging, and shelf labels.
- Business cards and email signatures.
- Posters, flyers, and storefront windows.
- Linking straight to a WhatsApp conversation.

## Error correction matters

Higher error-correction levels let a code stay scannable even if it's printed small, curved, or partly covered by a logo — at the cost of a denser code. Medium suits most uses.
