Questions
Do these QR codes expire?
No. The details are stored in the code itself, not behind a redirect, so they work for as long as the details are correct.
Which error correction level should I use?
Medium suits most uses. Choose a higher level if the code will be printed small, on a curved surface, or might get dirty. Higher levels make the code denser.
SVG or PNG?
SVG for print and design tools, because it stays sharp at any size. PNG for websites, documents and messages.
Can I change the colours?
Yes, but keep strong contrast, with a dark code on a light background. Many scanners can’t read light codes on dark backgrounds.
