Links, plain text, WiFi networks, contact cards — generate a QR code, customize the colors, and download it. Nothing is ever sent to a server.
Scan with your phone's camera to test it before downloading.
4QRCodeOnline covers the QR codes people actually need: a link to a website, a WiFi network guests can join without typing the password, a digital business card, or a pre-filled email. Pick a type, fill in the fields, and the code updates as you type.
Choose Text/URL, WiFi, Contact, or Email above, enter the details, and adjust the color and size if you like. When it looks right, download it as a PNG for everyday use or an SVG if you need it sharp at a large size, like on a poster or sign.
These are static codes: the data is encoded directly into the black-and-white pattern itself. That means the code keeps working forever, with no dependency on 4QRCodeOnline staying online and no scan limit.

No. These are static QR codes — the data is encoded directly into the pattern, so the code works forever and doesn't depend on our site staying online.
No. The QR code is generated entirely in your browser with JavaScript. Nothing you type, including WiFi passwords or contact details, is sent anywhere.
PNG is a fixed-size image, good for most uses. SVG is a vector format that stays sharp at any size, which is better for printing large or placing in a design tool.
