For example, to create a WiFi QR code, select "WiFi Network" as the type, enter your network name (SSID) like "MyHomeWiFi", enter your password, select the encryption type (usually WPA/WPA2), and click generate. The resulting QR code can be printed and placed in your home or office. When guests scan it with their phone camera, they'll automatically connect to your WiFi network without typing the password. Similarly, a vCard QR code with your name, phone, and email can be scanned to instantly add your contact to someone's phone.
A QR code (Quick Response code) is a two-dimensional barcode that stores information in a pattern of black and white squares. When scanned by a smartphone camera or QR code reader app, the encoded information is instantly decoded and displayed or acted upon.
Yes, your data is completely secure. This QR code generator runs entirely in your web browser using client-side JavaScript. No data is sent to any server, and no information is stored or tracked. All QR code generation happens locally on your device.
PNG is a raster image format that stores images as a grid of pixels, perfect for most uses. SVG is a vector format that uses mathematical descriptions, allowing it to scale to any size without losing quality. For QR codes, both work well, but SVG offers better scalability.
Error correction level determines how much of the QR code can be damaged while still being scannable. Levels range from L (Low, ~7%) to H (High, ~30%). For most uses, Medium (M) is recommended. Use High (H) if the QR code might be partially damaged or printed on rough surfaces.
This tool is for informational purposes only and does not provide financial, legal, medical, or professional advice. QR codes generated by this tool are standard format codes that work with most QR code readers. However, compatibility may vary with different devices and scanning apps. Always test your QR codes before printing or distributing them widely. This tool does not guarantee compatibility with all QR code readers or devices.

QR codes have countless practical applications in both personal and business contexts. Here are some common use cases:
After generating your QR code, you can download it in two formats:
You can also copy the QR code image directly to your clipboard using the "Copy Image" button. This feature works in modern browsers and allows you to paste the QR code into other applications like image editors, document processors, or messaging apps.
When choosing between PNG and SVG, consider your use case: PNG is better for photos and complex graphics, while SVG is better for simple graphics that need to scale. For QR codes, both formats work excellently, but SVG offers better scalability if you need the code at various sizes.

PNG is a raster image format that stores images as a grid of pixels. It's perfect for most uses and maintains quality at the specified size. SVG is a vector format that uses mathematical descriptions of shapes, allowing it to scale to any size without losing quality. For QR codes, both work well, but SVG offers better scalability if you need the code at various sizes. PNG is more universally supported, while SVG is ideal for designs that need to scale.
Error correction level determines how much of the QR code can be damaged or obscured while still being scannable. Levels range from L (Low, ~7% damage tolerance) to H (High, ~30% damage tolerance). Higher levels create more complex QR codes but are more resilient. For most uses, Medium (M) is recommended as it balances complexity and reliability. Use High (H) if the QR code might be partially damaged, printed on rough surfaces, or viewed at angles.
Yes, you can customize both the foreground (QR code pattern) and background colors using the color pickers. However, be careful with color choices - QR codes need sufficient contrast between foreground and background to be scannable. Very light foreground colors or very dark backgrounds may make the code unreadable. Black on white is the most reliable combination, but other high-contrast combinations work well too.
The quiet zone (also called margin) is the white space around the QR code pattern. It's essential for QR code scanners to identify and read the code correctly. The margin should be at least 4 modules wide (the standard size), but you can adjust it from 0 to 8. A larger margin makes the code easier to scan, especially when printed or displayed in contexts where edges might be cut off. We recommend keeping the margin at 4 or higher for best results.
To create a WiFi QR code, select "WiFi Network" as the QR code type, then enter your network name (SSID), password, and encryption type (WPA/WPA2, WEP, or None for open networks). You can also mark the network as hidden if applicable. Once generated, anyone who scans the QR code will be able to connect to your WiFi network automatically without typing the password. This is especially useful for guests, customers, or events.
Yes, select "vCard (Contact)" as the QR code type and fill in the contact information including name (required), phone number, email, company, and website. When someone scans the QR code, their phone will automatically add the contact to their address book with all the provided details. This is perfect for business cards, networking events, or sharing contact information digitally.
