Frequently Asked Questions
What can I encode in a QR code?
You can encode any text, including URLs, email addresses, phone numbers, Wi-Fi credentials, plain text messages, and more. Our tool provides preset templates for common formats.
What are error correction levels?
QR codes have four error correction levels (L, M, Q, H). Higher levels allow the QR code to remain readable even if partially damaged or obscured, but result in a denser code. Level M (15%) is recommended for most uses.
Is this QR code generator free?
Yes, completely free with no limits. QR codes are generated entirely in your browser using JavaScript — no server processing, no watermarks, no sign-up required.
