Frequently Asked Questions
What can I encode in a QR code?
You can encode URLs, plain text, email addresses, phone numbers, WiFi credentials, vCards, and more. Most QR code scanners handle all of these automatically.
What does error correction level mean?
Error correction allows a QR code to be read even if part of it is damaged or obscured. Higher levels (H=30%) can tolerate more damage but produce denser codes.
Will the generated QR code work offline?
Yes. Once generated, the QR image is rendered locally in your browser and can be downloaded as PNG for offline use.
