Frequently Asked Questions
What is Error Correction?
Error correction allows a QR code to be scanned even if part of it is damaged or obscured. Level L (7%) is smallest and most compact. Level H (30%) adds the most redundancy — useful if you plan to print the QR on a surface where part of the code might be covered (e.g. by a logo overlay).
What can I encode in a QR code?
Any text up to ~4,296 alphanumeric characters can be encoded — including website URLs, email addresses (mailto:name@example.com), phone numbers (tel:+1234567890), Wi-Fi credentials, vCard contact data, and plain text messages.
Does it work offline?
Yes! Once the page has loaded in your browser, no internet connection is required to generate, customize, or download your QR codes.
