{{ 'public://sea.jpg'|file_url }}
```
In order to generate absolute URL set "relative" parameter to `false`.
```twig
{{ 'public://sea.jpg'|file_url(relative=false) }}

{{ node.field_media|file_url }}

It is also possible to extract file URL directly from an entity.
```twig
{{ image|file_url }}
{{ media|file_url }}
```
