Enter some content to generate a QR Code

QR codes bridge the gap between physical and digital spaces by encoding text, URLs, Wi-Fi credentials, and more into a scannable pattern. This generator gives you control over colors, error correction levels, and content types so you can create professional-looking codes for any use case.

How to Generate a QR Code

Choose a content type from the tabs at the top: Text/URL for plain text or web links, Wi-Fi to share network credentials, or Email to pre-fill a message. Enter the required details and the QR code updates instantly in the preview panel on the right.

Use the color pickers to customize the foreground and background, and adjust the error correction level to balance data density with resilience. When you are happy with the result, click Download PNG to save the image.

QR Code Best Practices

Always test your QR code on multiple devices before printing. Ensure there is enough quiet space (white margin) around the code so scanners can detect the edges. Avoid placing QR codes on reflective or curved surfaces that can distort the pattern.

Choose a higher error correction level if the code will be placed in an environment where it might be partially obscured. For printed materials, use a minimum size of 2 cm × 2 cm and maintain high contrast between the foreground and background colors.

About QR Codes

A QR (Quick Response) code is a two-dimensional barcode that can store various kinds of information, such as text, URLs, contact information, and more. It can be quickly read by a smartphone camera, making it a popular choice for bridging the gap between the physical and digital worlds.

Error Correction Levels:

Low (L): Allows recovery of up to 7% of damaged data. Use for clean environments.
Medium (M): Allows recovery of up to 15%. A good general-purpose choice.
Quartile (Q): Allows recovery of up to 25%. Use when the code might be dirty or damaged.
High (H): Allows recovery of up to 30%. Best for industrial environments, but reduces data capacity.

Frequently Asked Questions

What can I encode in a QR code?

You can encode plain text, URLs, email addresses, phone numbers, WiFi credentials, or any other text data. The tool generates a QR code from whatever you enter.

How do I generate a QR code?

Enter your text or URL in the input field, customize the size and error correction level if needed, and click "Generate." The QR code appears instantly and can be downloaded.

What download formats are supported?

You can download the QR code as a PNG image (good for most uses) or as SVG (ideal for scaling to any size without losing quality).

What is error correction level?

Error correction determines how much damage a QR code can sustain and still be readable. Higher levels (H = 30%) allow the code to be scanned even if partially obscured or damaged.
