Generate QR codes for websites, Wi-Fi networks, text, email, phone numbers, SMS messages, contacts, events, and locations.
Use this QR code generator to make scannable codes for websites, Wi-Fi networks, plain text, email, phone numbers, SMS messages, contacts, calendar events, and map locations. QR codes are useful for print materials, signs, packaging, menus, handouts, events, and quick mobile actions.
The tool formats your fields into the appropriate QR payload, generates the code in the browser, and renders downloadable PNG and SVG outputs. Larger payloads need more QR modules, so shorter URLs and simpler text usually produce cleaner, easier-to-scan codes.
