Frequently Asked Questions
What is error correction in QR codes?
QR codes include redundant data that allows them to be read even when partially damaged or obscured. There are four levels: L (7% recovery), M (15%), Q (25%), and H (30%). Higher correction allows more damage tolerance but produces denser codes.
What is the maximum amount of data a QR code can hold?
A QR code can store up to about 3,000 alphanumeric characters or 7,000 numeric digits. However, shorter content produces simpler, easier-to-scan codes. For best results, keep URLs and text concise.
Should I download PNG or SVG?
Use SVG for print materials because it scales to any size without losing quality. Use PNG for digital use (websites, emails, social media). SVG files are also typically smaller in file size.
