What is a QR Code Generator?
A QR Code (Quick Response code) is a two-dimensional barcode that can store hundreds of characters of data in a small square image. Modern smartphones can scan them instantly using their camera. Our free QR code generator lets you create QR codes for any URL, plain text, email address, phone number, or SMS message in seconds.
QR codes are used extensively in marketing (linking print materials to websites), restaurants (digital menus), event management (ticket verification), and product packaging (accessing additional information). The error correction feature makes QR codes readable even if part of the code is damaged or covered.

FAQ
What error correction level should I choose?
Use M (Medium) for most use cases — it offers a good balance. Use H (High) if you plan to print the QR code on physical materials where it may get scratched or if you want to overlay a logo on top. Higher error correction increases QR code density but still scans reliably.
Are QR codes permanent?
Static QR codes (like this tool generates) are permanent — the data is encoded directly into the code and cannot change. If you need to edit the destination URL after printing, use a dynamic QR code service that uses a redirect URL.
