Converts plain text to Base64-encoded binary data.

## Availability

<table>
  <tr>
    <td>Marketing Cloud Engagement</td>

## Syntax

```
Base64Encode(stringToEncode, characterEncoding)
```

The `Base64Encode()` function has two parameters:

- `stringToEncode` (string): Required. The string to encode to Base64.
- `characterEncoding` (string): The character encoding type to use when encoding the string. Accepted values are `ASCII`, `UTF-7`, `UTF-8`, `UTF-16`, and `UTF-32`.

## Usage

To use the function, pass it the string that you want to encode. Optionally, specify the type of character encoding to use.

```
%%[
  Var @couponCode, @couponCodeB64
  Set @couponCode = "6dn28uqxocqu"
  Set @couponCodeB64 = Base64Encode(@couponCode)
]%%
<p>%%=v(@couponCodeB64)=%%</p>
```

The example code outputs a string encoded in Base64.
