Error Correction Level

Higher levels stay scannable even if part of the code is damaged or covered, at the cost of a denser pattern. Use High if you plan to place a logo in the center.

Frequently Asked Questions

Is my text sent to a server?

No, everything is processed entirely in your browser and never uploaded anywhere.

Is there a character limit?

QR codes can technically hold thousands of characters, but more characters means a denser, harder-to-scan pattern. Short content like URLs works best.

Can I create a QR code for a Wi-Fi password?

Yes, use the format WIFI:T:WPA;S:NetworkName;P:Password;; . Keep in mind anyone who scans it can see the password.

Will it still scan well when printed?

Yes, set the error correction level to High and generate it at a large enough size, and it should scan reliably even on printed materials.
