What can go into a QR code
Any text works, a website link, a Wi-Fi password, a piece of contact info, or a plain message. The more characters you encode, the denser the resulting pattern, so very long text produces a more intricate code that may need to be printed larger to stay scannable.
Tips for a QR code that scans reliably
- Keep decent contrast: this generator uses black on white by default, which scans best.
- If printing small (like on a business card), keep the encoded text short, a shortened URL works better than a long one.
- Leave a plain white margin (a "quiet zone") around the code when placing it in a document.
Frequently asked questions
Does this store the links or text I generate codes for?+
No. The QR code is drawn entirely in your browser. Nothing you type is sent to a server or saved.
Can I use this for Wi-Fi sharing or contact cards?+
Yes, as long as you format the text the way a scanning app expects, for example, a Wi-Fi QR typically needs the format WIFI:S:NetworkName;T:WPA;P:Password;; Paste that exact string into the box above.
