FAQ
Do the codes expire?
No. These are static QR codes — content is encoded in the pattern itself and works forever.
How much can they hold?
Up to ~1,800 Chinese characters or ~4,000 ASCII characters, but shorter content makes cleaner, easier codes.
Any color restrictions?
Custom colors are fine, but keep modules clearly darker than the background for reliable scanning.
About this QR Code Generator
QR codes are generated entirely in your browser with error-correction level M (~15% recoverability). Strong contrast — dark modules on a light background — scans best; when customizing colors, keep a clear brightness difference.
