Question 1

What is a QR code?

Accepted Answer

A QR code (Quick Response Code) is a two-dimensional barcode developed by Denso Wave in Japan in 1994. It can store significantly more information than traditional barcodes and can be scanned instantly using a smartphone camera. QR codes are widely used to share URLs, text, contact information, Wi-Fi credentials, and more.

Question 2

How much data can a QR code hold?

Accepted Answer

The maximum data capacity of a QR code is 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. However, the more data you include, the more complex the code becomes and the harder it is to scan. For best results, we recommend keeping content to around 200 characters for text or URLs.

Are the generated QR codes safe?

Accepted Answer

Yes, they are safe. QR codes generated by this tool are created locally within your browser and no data is sent to any server. The downloaded PNG images contain no malicious code. However, please ensure the URLs or content you include in the QR code itself are safe and from trusted sources.
