What can I encode in a QR code?

You can encode plain text, URLs, Wi-Fi network credentials (SSID and password), email addresses, phone numbers, and SMS messages. The tool provides templates for each type.

Can I customize the QR code colors?

Yes. You can set custom foreground and background colors. Make sure there is sufficient contrast between the colors for reliable scanning.

What size QR code should I use?

For print, use at least 300x300 pixels. For web, 200x200 is usually sufficient. The tool generates scalable codes that you can resize. SVG format is ideal for print as it scales without quality loss.

Static QR codes (like those generated here) never expire. They encode data directly into the pattern. As long as the destination URL remains active, the QR code works forever. Only dynamic QR codes tied to paid redirect services can expire.

How do I create a QR code for Wi-Fi?

Select the Wi-Fi template, enter your network name (SSID), password, and encryption type (WPA/WPA2). The generated QR code can be scanned by any smartphone to connect instantly without typing the password.

Why isn't my QR code scanning?

Common issues: insufficient contrast between foreground and background colors, QR code is too small for the scanning distance, or the code is damaged/partially obscured. Ensure at least 4:1 contrast ratio and include a quiet zone (white border) around the code.
