Create free QR codes for URLs, text, email, phone numbers, and WiFi networks. Download as PNG.
A QR (Quick Response) code is a two-dimensional barcode that stores information in a pattern of black and white squares. When scanned with a phone camera, it instantly opens a URL, displays text, composes an email, dials a phone number, or connects to a WiFi network. QR codes were invented in 1994 by Denso Wave for tracking automotive parts and have since become ubiquitous in marketing, payments, menus, event tickets, and more.
Business cards: Link to your website, portfolio, or LinkedIn profile. Restaurant menus: Contactless menus became standard during the pandemic and many restaurants have kept them. WiFi sharing: Print a QR code with your WiFi credentials so guests can connect with one scan instead of typing a long password. Event tickets: Encode ticket information for fast scanning at the door. Product packaging: Link to instructions, warranty registration, or reviews. Payments: Services like Venmo and PayPal use QR codes for person-to-person payments.
On most modern phones, simply open the camera app and point it at the QR code. A notification or link will appear automatically. On iPhone (iOS 11+), the built-in camera app scans QR codes natively. On Android (8.0+), the camera or Google Lens handles it. No separate app is needed on any phone made after 2018.
