Frequently Asked Questions
What is the maximum data a QR code can hold?
A QR code can store up to 4,296 alphanumeric characters or 7,089 numeric digits. For URLs, keep them under 300 characters for reliable scanning. Longer content generates denser patterns that may be harder for older phone cameras to read.
What is error correction level?
QR codes have four error correction levels: L (7%), M (15%), Q (25%), H (30%). Higher levels make the code scannable even when partially damaged or obscured — useful for printed materials. Higher correction means a denser code pattern.
Do generated QR codes expire?
No. QR codes are static images that encode data directly. They never expire and will work as long as the content they link to is available. Unlike dynamic QR services, these codes have no tracking or expiration — they are yours forever.
