What is error correction in QR codes?

Error correction allows a QR code to be read even when part of it is damaged or obscured. There are four levels: Low (7% recovery), Medium (15%), Quartile (25%), and High (30%). Higher levels make the code more durable but also denser, which requires more space to scan reliably.

Can I use custom colors for my QR code?

Yes, you can set custom foreground and background colors. However, maintain sufficient contrast between them—dark foreground on light background works best. Very low contrast can make the code unscannable by some camera apps.

What is the difference between PNG and SVG download?

PNG is a raster image best for digital screens and small-scale printing. SVG is a vector format that scales to any size without quality loss, making it ideal for large-format printing like posters, banners, and billboards.

No, QR codes generated from static data like URLs or text never expire. They'll work as long as the encoded content is valid. If you encode a URL, the QR code will continue to work as long as that URL remains active.

How much data can a QR code hold?

A standard QR code can hold up to 4,296 alphanumeric characters or 2,953 bytes of binary data. However, more data means a denser code that's harder to scan. For URLs, keep them as short as possible for best results.
