# QR-Code

You can get the QR code for your tunnel URL within the terminal by pressing **`c`** or **`u`**.

To hide the qr code again, just press **`Esc`**.

## ASCII

In normal mode just press `c` to display QR-Code.
It will display QR-Code for the tunnel url in ASCII format like this.

You can use the **arrow keys** to change the QR Code for different urls. Press `Esc` to return to normal page.

This QR Code is printed using ASCII characters. Thus, it is compatible with most of the terminals. However, it might not fit into small terminal windows. For a more compact QR Code, use the unicode version.

## Unicode

To get a compact QR Code, we have option for unicode QR. Press `u` to print QR-Code drawn using unicode.

Unicode QR-Code can easily fit inside a 80x25 terminal. However, the terminal must have support for unicode character-set. Otherwise the result is unpredictable.

# Always show QR-Code

Pinggy also supports keywords `qr` and `aqr` while creating tunnel to print QR in the TUI like the following.

This keyword needs to be passed with the username as following:


```bash
# SSH - no install, works anywhere the ssh client is available
ssh -p 443 -R0:localhost:8000 qr@free.pinggy.io
```

```bash
# Pinggy CLI - install with: npm install -g pinggy (or download the binary)
./pinggy -p 443 -R0:localhost:8000 qr@free.pinggy.io
```


Here `qr` would produce QR code in unicode while `aqr` would produce QR code in ASCII.
