В ОС Linux есть стандартная утилита `base64`, которая на вход принимает данные.
> base64 присутсвует даже в [BusyBox](https://www.busybox.net/BusyBox.html)
(Ctrl+F > base64)
Ниже представлен пример, которые скачивает **SVG** код **twemoji**
и преобразует его с строку **base64**.
```sh
curl https://raw.githubusercontent.com/twitter/twemoji/master/assets/svg/1f4a2.svg | base64

Остаётся только подставить данные типа (MIME) и использовать строку
в любимом ЯП.
Для **SVG** строка будет выглядеть так:
```text
data:image/svg+xml;base64,<BASE64_STRING>
```
