About this QR code generator

This free QR code generator creates scannable QR codes for URLs, plain text, email addresses, phone numbers, and WiFi credentials — all in your browser with no account required. Generated codes are available to download instantly as PNG files at your chosen size.

QR codes generated here use the highest error correction level (Level H), which means they remain scannable even if up to 30 percent of the code is damaged or obscured. This makes them ideal for print use where wear and tear can affect readability.

QR code types explained

Phone QR codes: Dials a phone number directly when scanned. Great for business signage and contact cards.

Best practices for using QR codes

Always test your QR code by scanning it with a smartphone before printing or publishing.
For print at business card size, use at least 300px and print at 300 DPI or higher.
For posters or signage, generate at 400px and scale up in your design software.
Leave a white border around your QR code. Most scanners need at least 4 modules of white space around the edges to read correctly.
Dark QR code on a white or light background always scans better than the reverse. Avoid placing QR codes on busy or patterned backgrounds.
For WiFi QR codes, regenerate and reprint if you change your network password.

Frequently asked questions

Do QR codes expire?

QR codes generated here are static — they encode the data directly and never expire. As long as the URL or content they point to remains valid, the QR code will work forever. Dynamic QR codes from other services can expire if you stop paying for the service.

How do I scan a QR code?

On iPhone, open the Camera app and point it at the QR code. A notification will appear at the top — tap it to open the link. On Android, most camera apps work the same way. If yours does not, download a free QR scanner app from the Play Store.

Can I customize the colors of my QR code?

Yes. Use the color picker to choose any dark color for your QR code. Always keep the background white or very light — low contrast between foreground and background reduces scan reliability. Test scanning after any color change before printing.

Is there a limit to how much text a QR code can hold?

Yes. QR codes can hold up to about 4,296 characters of alphanumeric data. The more data you encode, the denser and harder to scan the code becomes. For long URLs, consider using a URL shortener before generating the QR code.
