Create custom QR codes for URLs, text, emails, and WiFi networks in seconds. Free online tool with instant generation and download.
You can create QR codes for websites (URLs), plain text, email addresses (with optional subject), and WiFi network credentials (SSID, password, and encryption type). The WiFi QR code allows users to scan and connect to your network instantly.
Choose from 150x150, 200x200, 300x300, or 400x400 pixels. Larger sizes are better for print materials and ensure scannability from a distance. Smaller sizes work well for digital displays and mobile apps.
Absolutely! All QR codes generated on our site are completely free with no watermarks, no expiration, and unlimited generation. Use them for personal or commercial projects without any restrictions.
Most modern smartphones (iPhone and Android) have built-in QR code scanners in the camera app. Simply open the camera and point it at the QR code. A notification will appear with the encoded content. Alternatively, use a free QR code scanner app from your app store.
Once generated, QR codes are static and cannot be edited. If you need to change the content, you must generate a new QR code. The new QR code will look different due to the encoding change. Always test QR codes before printing.
No, QR codes themselves never expire. However, the content they point to (like URLs) may change or become unavailable. For website QR codes, ensure the URL remains active. For dynamic QR codes (redirect services), the redirect link may expire depending on the service provider.
