QR code generator

How it works

1. Pick what the code should carry: a URL for product pages and review links, text for anything else, or the Wi-Fi payload for the counter.
2. The encoder builds the symbol with error correction, so a scuffed print or a coffee stain still scans.
3. Download PNG for screens and marketplaces, SVG for print, and keep the white border when you place it.

These are static codes: whatever you encode is baked into the ink. That is a feature and a limit at once, and it is why nothing here needs an account.

Questions sellers ask

Which QR standard is this?

ISO/IEC 18004, byte mode, error correction level M: the same trade every printed label makes, roughly 15% of the symbol spent on damage recovery. Versions 1 to 10, which holds up to 213 bytes of payload.

Why is there white space around the code?

That is the quiet zone, four modules wide, and the standard requires it. A QR printed flush to an edge frequently will not scan: the camera needs the border to find where the symbol starts.

What is the Wi-Fi mode for?

It builds the standard Wi-Fi payload that phones read as a network join. Print it on the counter, the delivery box or the market stall, and customers connect without you reading a password aloud. The password is inside the code, so anyone who can scan it can join: use a guest network if that bothers you.

Do these codes expire or stop working?

No. A QR code is ink, not a service: it encodes whatever you typed, statically, forever. The URL it points at can die, but the symbol itself cannot lapse, and nothing here phones home.
