# `data_uri`

The `data_uri` filter generates a URL using the data scheme as defined in RFC 2397:

    {{ image_data|data_uri }}

    {{ source('path_to_image')|data_uri }}

    {# force the mime type, disable the guessing of the mime type #}
    {{ image_data|data_uri(mime: "image/svg") }}

    {# also works with plain text #}
    {{ '<b>foobar</b>'|data_uri(mime: "text/html") }}

    {# add some extra parameters #}
    {{ '<b>foobar</b>'|data_uri(mime: "text/html", parameters: {charset: "ascii"}) }}

Note

The `data_uri` filter is part of the `HtmlExtension` which is not installed by default. Install it first:

    $ composer require twig/html-extra

Then, on Symfony projects, install the `twig/extra-bundle`:

    $ composer require twig/extra-bundle

Otherwise, add the extension explicitly on the Twig environment:

    use Twig\Extra\Html\HtmlExtension;

    $twig = new \Twig\Environment(...);
    $twig->addExtension(new HtmlExtension());

Note

The filter does not perform any length validation on purpose (limit depends on the usage context), validation should be done before calling this filter.

## Arguments

- `mime`: The mime type

- `parameters`: A mapping of parameters
