Guide & explanation
The QR Code Generator turns text or a URL into a QR code that a phone camera can scan.
Error-correction level
A QR code stores redundant data so it stays readable even when partly damaged or covered.
| Level | Damage tolerance |
|---|---|
| L | ~7% |
| M | ~15% |
| Q | ~25% |
| H | ~30% |
Higher levels are more robust but the pattern gets denser, so it needs a larger or sharper print. H is a good choice when a logo will be overlaid on the code.
Margin (quiet zone)
The empty area around the code. The spec recommends at least 4 modules; less than that and some scanners fail to read it.
Output
- SVG — vector, crisp at any size, ideal for print.
- PNG — a 512 px raster, convenient for the web and quick pasting.
