Notes
- How much text fits depends on the error correction level. If a long text or URL fails to generate, try lowering the error correction level.
- After generating, we recommend testing that the code actually scans with a smartphone camera.

Glossary
QR code
A two-dimensional barcode made of a black-and-white grid that encodes data. It can be scanned quickly with a smartphone camera to read a URL or text.
Error correction level
How much redundant data the QR code carries so it can still be read even if part of it is smudged or damaged. A higher level tolerates more damage, but makes the pattern denser.
Quiet zone
The blank margin required around a QR code. If this margin is too narrow or gets cropped, a camera may fail to recognize the code's boundaries and cannot scan it.
FAQ
What is the error correction level and which should I choose?
It is the amount of redundant data that lets a QR code be read even if part is dirty or damaged. Higher levels are more robust but hold less data. A medium level is fine for ordinary URLs.
Why can't I generate a code from long text?
Capacity depends on the error correction level. If long text or a URL fails, lower the level or shorten the content.
Can I use the QR codes commercially?
The generated codes are yours to use. "QR Code" is a registered trademark of Denso Wave Inc. When printing, test that a smartphone can actually scan it.
