QR Code Generator
What is this Tool?
QR Code (Quick Response Code) is a type of 2D barcode designed to be scanned quickly. Developed by Denso Wave in 1994, it can store various data such as URLs, text, contact information, and Wi-Fi details.
Scanning a QR code with a smartphone camera gives instant access to the information, making it useful for marketing, payments, ticketing, business cards, and more. wowfree's QR Code Generator allows you to create high-quality QR codes directly in your browser without registration or installation.

FAQ
Q. Do QR codes expire?
The QR code itself does not expire. However, if the URL in the QR code is changed or deleted, the page will not be accessible. Static text or contact information works permanently.
Q. Can I use generated QR codes commercially?
Yes, you can use them commercially for free. The generated QR codes follow standard specifications and can be used for any purpose.
Q. What if the QR code doesn't scan?
Scanning may be difficult if the QR code is too small, distorted, poorly printed, or if lighting is poor. Print at least 2x2cm size and ensure sharp black-and-white contrast.
Q. How much data can a QR code hold?
QR codes can hold up to about 4,296 alphanumeric characters. However, more data makes the QR code more complex and harder to scan, so it's recommended to store short URLs or key information.
Q. How many can I generate at once in Bulk Mode?
There is no technical limit, but considering browser memory and performance, we recommend generating within 100 at a time. If you need more, please generate them in batches.
