What is QR Code Generator?
QR Code Generator creates high-quality, scannable QR codes from URLs, plain text, Wi-Fi credentials, or contact information. Customize the output size to match your needs, choose foreground and background colors to align with your brand, and select from four error correction levels (L, M, Q, H) to balance data density with scan reliability. Higher error correction means the code can still be read even if partially obscured or damaged. Download the finished QR code as a PNG image or copy it directly to your clipboard for quick use in documents, presentations, or web pages.

Frequently Asked Questions
Can I use the generated QR codes commercially?
Yes, generated QR codes can be used freely for both commercial and non-commercial purposes. Use them on business cards, flyers, product packaging, websites, and more.
What is error correction level?
This feature allows QR codes to be read even if part of them is dirty or damaged. There are 4 levels: L (7%), M (15%), Q (25%), H (30%). Higher levels improve scan reliability but increase QR code size. For printed materials or packaging where dirt or wear is possible, use Q or H.
Will changing colors affect scanning?
As long as there is sufficient contrast between foreground and background colors, there should be no issues. However, making the foreground lighter than the background or using low-contrast combinations may cause scanning errors.
How do I create a QR code that opens Wi-Fi automatically?
Enter your Wi-Fi credentials in the format WIFI:T:WPA;S:YourSSID;P:YourPassword;; as the input text. When scanned on Android or iOS, it will prompt the user to join the network directly.
Is my input data stored on a server?
No. QR code generation uses the qrcode library which runs as JavaScript in your browser. Input data is not transmitted to any server.
