URLs, plain text, email addresses, phone numbers, SMS messages, Wi-Fi credentials, and vCard contact information are all supported. Select your content type for properly formatted encoding.

No -- QR codes generated here are static and never expire. The data is encoded directly in the image with no server-side component required to scan them.

Low (L) for simple digital displays, Medium (M) for most printed uses, Quartile (Q) for textured or slightly damaged surfaces, and High (H) when adding a logo to the center of the code.

Yes -- SVG format scales to any size without quality loss, making it ideal for banners, signs, and other large-format print materials. Use PNG for digital uses.

Yes -- upload a logo image and it will be placed in the center. Set error correction to High (H) to ensure the code remains scannable with the logo overlay covering some modules.

As a general rule, the minimum print size is 2x2 cm (about 0.8 inches) for most scanning distances. Simpler content with Low error correction can be printed smaller.

Troubleshooting

QR code does not scan
Ensure sufficient contrast between foreground and background colors. Try High error correction level and test at different physical sizes. Very small QR codes may not scan reliably in poor lighting.
Logo causes scan failures
Use High (H) error correction when adding a logo. Keep the logo under 25% of the QR code area to preserve enough data modules for reliable scanning.
QR code links to the wrong page
Verify the URL is complete including the https:// prefix. Test-scan immediately after generating to catch errors before printing or publishing.
