What can I encode in a QR code?

You can encode any text content including URLs, plain text, email addresses, phone numbers, WiFi credentials, and more. Most QR code scanners will automatically detect the content type.

What size should I choose for my QR code?

For digital use (websites, social media), 200px is usually sufficient. For print materials like flyers or business cards, 400px or 600px provides better quality when scaled. Larger sizes produce sharper results when printed.

Can I customize the colors of my QR code?

Yes. Use the foreground and background color pickers to match your brand colors. Ensure enough contrast between the two colors so scanners can read the code reliably.

Is there a character limit for QR codes?

QR codes can store up to approximately 4,296 alphanumeric characters. However, shorter content produces simpler, more scannable codes. For best results, keep URLs and text concise.

Is this tool free to use?

Yes, completely free with no signup required. QR codes are generated entirely in your browser — no data is sent to any server.

What content types can I encode in a QR code?

You can encode URLs, plain text, email addresses, phone numbers, WiFi credentials, and more. Most smartphone QR scanners automatically detect the content type and take the appropriate action (open a link, compose an email, join a WiFi network).

Is there a practical limit to QR code content length?

QR codes can technically store up to about 4,000 alphanumeric characters, but shorter content produces simpler codes that are easier to scan. For best results, keep your content concise — especially for printed materials scanned at a distance.

Can I customize the QR code colors?

Yes. Use the foreground and background color pickers to set any colors you like. Just ensure there is strong contrast between the two so scanners can read the code reliably.

What image format is the downloaded QR code?

The QR code downloads as a PNG image. PNG is ideal for QR codes because it uses lossless compression, preserving the sharp edges that scanners need to read the code accurately.
