What is a QR Code Generator?
QR codes bridge print and digital — menus, posters, packaging and payment stands all use them to put a link one camera-scan away.
This generator encodes your text or URL into a QR code locally and renders it as a crisp PNG at the size you choose. No account, no watermark, and the content never leaves your browser.
Print sizing is where QR codes fail in the wild: the reliable minimum is about 2 x 2 cm for a short URL scanned at arm's length, bigger for posters scanned across a room. Short URLs also scan faster — fewer characters mean coarser, more forgiving modules — so encode example.com/menu rather than a 200-character tracking link.
How to use the QR Code Generator
- Type or paste the URL or text.
- Pick a size — larger for print, smaller for screens.
- Download the PNG (or right-click to copy it).
Frequently asked questions
Why won't my QR code scan?
Usually contrast or quiet zone: keep dark-on-light with a clean white margin around the code, and avoid stretching it. Very long text also makes codes dense and finicky — shorten the URL.
Can I put a logo in the middle?
Small overlays work because QR codes carry error correction, but every pixel you cover spends that budget. This generator produces clean codes; add overlays sparingly and always test-scan.
Do these QR codes expire?
Never. The code is a direct encoding of your text — there is no redirect service in the middle that could shut down.
What size should I use for print?
At least 512×512 px for A4 posters, larger for banners. Also keep a quiet white margin around the code.
Can I encode Wi-Fi credentials or phone numbers?
Yes — paste standard formats like WIFI:T:WPA;S:name;P:pass;; or tel:+91… and camera apps will act on them.
Is my link tracked?
No. The QR encodes your link directly, with no shortener or tracking layer added.
