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.

LevelDamage 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.
