QR codes (Quick Response codes) are two-dimensional barcodes invented in 1994 for the automotive industry. Today, they are ubiquitous in marketing, payments, and information sharing due to their fast readability and large storage capacity.
Modern smartphones can scan QR codes directly from the camera app, making them an incredibly convenient way to share information. Whether you need to share a website link, WiFi credentials, or contact information, QR codes provide a seamless experience.

What is a QR code?
A QR code (Quick Response code) is a two-dimensional barcode that can store various types of data. When scanned with a smartphone camera, it quickly directs users to websites, displays text, connects to WiFi networks, or saves contact information.
What types of QR codes can I create?
This tool supports three main types: URL/Text QR codes for websites or any text content, WiFi QR codes that let others connect to your network without typing the password, and vCard QR codes for sharing contact information like name, phone, email, and address.
Do QR codes expire?
No, the QR codes generated by this tool are static and never expire. They contain the data directly encoded in the QR code image. However, if you encode a URL, the QR code will only work as long as that URL remains active.
What file formats can I download?
You can download QR codes in two formats: PNG (raster image, ideal for web use and sharing) and SVG (vector format, perfect for printing at any size without quality loss). Both formats are supported for all QR code types.
Can I customize the QR code colors?
Yes, you can customize both the foreground color (the QR code pattern) and the background color. Use the color pickers to choose any color you want. High contrast between foreground and background ensures better scanability.
Is there a limit to how much data I can encode?
QR codes have a maximum capacity of about 3KB of data. For URLs and WiFi credentials, this is rarely an issue. For vCards, keep the information concise. Longer data results in more complex QR codes that may be harder to scan.
