Common questions

Do these QR codes expire?

No. The code holds your link or details directly, not a short link through our server, so it keeps working forever, even if this website disappeared. Many free QR sites create codes that stop working after a trial.

Is it really free, with no limit?

Yes. There is no sign-up, no watermark, no limit on how many codes you make, and you can use them commercially, including on products, packaging and printed material.

How do I make a QR code for my Wi-Fi?

Choose Wi-Fi, type the network name and password exactly as they are, and pick the security type, which is WPA/WPA2 for almost every home router. Anyone who scans the code with a phone camera can join without typing the password.

How do I make a UPI payment QR code?

Choose UPI, enter your UPI ID (like yourname@okbank) and the name to show. Add an amount for a fixed-price code, or leave it empty so the payer types the amount. Scan it with any UPI app to test before printing.

Should I download PNG or SVG?

PNG for screens, documents and most everyday uses. SVG for professional printing, signs and anything that will be enlarged, because it stays perfectly sharp at any size.

How big should a printed QR code be?

At least 2 cm (about 0.8 inch) across for scanning from arm's length. A good rule is one tenth of the scanning distance: a code read from 1 metre away should be about 10 cm wide. Codes holding more text need to be larger.

What does error correction do?

It adds backup data so the code still scans if part of it is dirty, damaged or covered. L recovers about 7 percent, M about 15, Q about 25 and H about 30. Higher levels make the pattern denser, so use H only when you need it.

Why won't my coloured QR code scan?

Scanners need strong contrast: a dark code on a light background. Light codes on dark backgrounds, or pale colours like yellow on white, often fail. The generator warns you when the colours you picked may be hard to read.

Is my information stored?

No. The code is created by your browser on your own device. The links, passwords and details you enter are never sent to us or saved.
