What is QR Code?
A QR Code is a 2D barcode that any phone camera can scan. This generator runs locally so even sensitive payloads (Wi-Fi passwords, internal URLs) stay on your machine.
How to use
- Type or paste your text/URL.
- Pick an error correction level.
- Download the QR as PNG.
Example
Use this sample to confirm what QR Code does before pasting your own data.
Input
https://inbrowser.sh
Output
Downloadable PNG QR code, error-correction level M.
Wi-Fi, vCard, and arbitrary text are also supported.
When to use it
Use QR Code for quick local checks, debugging, documentation prep, and one-off conversions where opening a full IDE or command-line workflow would be slower. For production-critical data, always review the output before committing or shipping it.
