Error Correction Levels
The error correction level determines how much damage a QR code can withstand while staying scannable. Higher levels tolerate more, but hold less data:
| Level | Recovery rate | Best for |
|---|---|---|
| L | ~7% | High capacity, when the code stays intact |
| M | ~15% | Balanced choice, recommended for everyday use |
| Q | ~25% | Printed materials that may be partially covered |
| H | ~30% | Strongest tolerance, best with logos or wear |

PNG is a bitmap, great for screens and the web; SVG is a vector that scales without quality loss, ideal for printing. Use PNG for screen sharing and SVG for print materials.
Check whether the content is too long, the contrast is too weak, the image is too small, or the code is covered. Increase the error correction level and size, then regenerate.
