What is a QR code and how does it work?
A QR code (Quick Response code) is a two-dimensional barcode that can store various types of information. When scanned with a smartphone camera, it quickly directs users to websites, displays text, or performs other actions. Our generator creates scannable QR codes instantly.
What types of content can I put in a QR code?
You can generate QR codes for: Website URLs, plain text messages, email addresses, phone numbers, WiFi network credentials, contact information (vCard), and more. Select the appropriate type from the dropdown menu for optimal formatting.
Are the generated QR codes free to use?
Yes! All QR codes generated with our tool are completely free to use for personal and commercial purposes. There are no hidden fees, watermarks, or usage restrictions.
How long do the QR codes remain active?
The QR codes you generate are permanent and will never expire. Once you download the PNG image, you can use it indefinitely. The codes contain all the information directly in the image, so they don't rely on our servers to function.
Can I customize the colors of my QR code?
Yes! Our tool allows you to customize both the foreground and background colors of your QR code. However, ensure there's sufficient contrast between colors for reliable scanning. Dark on light combinations work best.
What's the maximum data a QR code can hold?
QR codes can store up to 4,296 alphanumeric characters or 2,953 bytes of binary data. For most practical purposes like URLs or contact information, this is more than sufficient. Our tool automatically optimizes the code for your content.
