About QR Code Generator
Generate a QR code for a link, plain text, a Wi-Fi network or a contact card, then download it as an image. The code is drawn in your browser, so nothing you encode is sent anywhere.
Error correction and why it matters
Every QR code carries redundant data so it still scans when part of it is damaged or covered. The four levels recover roughly 7%, 15%, 25% and 30% of the code. Higher correction means more modules packed into the same square, so the pattern gets denser and needs to be printed larger. Use Low for a clean screen or a large print, and High only when you plan to place a logo over the centre or expect wear.
How small can I print it?
As a rule of thumb, the code should be at least one tenth of the scanning distance: readable from 1 metre means roughly 10 cm across. Keep the quiet zone — the blank margin around the code, four modules wide — or scanners will fail no matter how large the code is. Never print light-on-dark unless you have tested it; many scanners expect dark modules on a light field.
Do QR codes expire?
A static code like this one never expires — the destination is encoded directly in the pattern, so it works as long as the link does. That is also its limitation: the URL cannot be changed later. If you need to redirect it after printing, encode a link you control and change where that link points.
