The QR Code Generator turns a link, text, Wi-Fi password, phone number, SMS or email into a QR code you can download as a PNG. Anyone who points a phone camera at it gets your content instantly — no typing, no spelling mistakes.
What size should I download?
512px suits most uses — screens, small prints and stickers. Choose 1024px for posters and banners that will be printed large, and 256px only for tiny on-screen uses.
Can I change the link inside a QR code later?
No — a printed QR code permanently holds the text you generated it with. If the destination may change, put a permanent page's address in the code (your profile or link page) and update that page instead.
Do I need to sign up or install anything?
No. The QR Code Generator is completely free, needs no account and nothing to install — it runs in your browser, and anything you type stays on your device.
