About QR Code

What is a QR code?

A QR (Quick Response) code is a 2D barcode that stores text — most often a URL — which any phone camera can scan instantly. They're everywhere: posters, menus, business cards and product packaging.

Text, URL and Wi-Fi

Encode a website link, any plain text, or a Wi-Fi network (SSID + password) so guests can join by scanning. The Wi-Fi mode builds the special WIFI: payload for you.

PNG vs. SVG

Download a PNG for quick use in documents and slides, or an SVG vector for print and large formats — SVGs stay sharp at any size.

Frequently asked questions

Are the QR codes really scannable?

Yes — they're built to the QR specification with proper error correction and verified to decode correctly.

Is my data uploaded to make the code?

No. The QR code is generated entirely in your browser; nothing is sent to a server.

Do the codes expire?

No. A QR code is static — it encodes your text directly and works forever.

Can I make a Wi-Fi QR code?

Yes — switch to Wi-Fi mode, enter your network name, password and security type, and guests can connect by scanning.
