What it does and when to use it
A QR code may contain a URL, text, or contact details. The code itself does not prove the destination is safe.

Paste a complete URL including https://, choose size, and generate the code.
How to understand the result
The image encodes exactly what you entered. It does not shorten URLs or track scans.
