Frequently Asked Questions

What is a QR code?

A QR code (Quick Response code) is a two-dimensional barcode that can store data like URLs, text, contact info, and more. Smartphones can scan QR codes instantly using their cameras, making them ideal for sharing links and information quickly.

What is error correction and which level should I choose?

Error correction allows QR codes to be readable even when partially damaged or obscured. L recovers 7% data loss — use for clean digital displays. M (default) recovers 15% — good for most uses. Q recovers 25% — for printed materials. H recovers 30% — use when adding a logo on top of your QR code.

Can I use colored QR codes? Will they still scan?

Yes, as long as there is sufficient contrast between the foreground (dark) and background (light) colors. Avoid light foreground colors on light backgrounds. Dark foreground on light background always works best. Pure black on white gives the most reliable scans.

What is the maximum data I can put in a QR code?

A QR code can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or about 2,953 bytes at error correction level L. In practice, shorter URLs and compact text produce smaller, easier-to-scan QR codes. Keep it under 500 characters for best results.

Does this tool send my data to a server?

No. QR code generation happens entirely in your browser using JavaScript. Your input — URLs, passwords, contact details, or any other text — is never sent to any server. Everything stays on your device.

What size should I use for print?

For most print uses, 512×512 or 1024×1024 px PNG is sufficient. At 300 DPI, 1024 px renders at about 3.4 inches (8.6 cm). For large-format printing like posters, use 1024 px and scale up in your design software — QR codes remain crisp since they're geometric patterns.
