Icon API

TYPO3 provides an icon API for all icons in the TYPO3 backend.


All icons must be registered in the icon registry. To register icons for your own extension, create a file called Configuration/Icons.php in your extension - for example: typo3conf/ext/my_extension/Configuration/Icons.php.

The file needs to return a PHP configuration array with the following keys:

   return [
       // icon identifier
       'mysvgicon' => [
            // icon provider class
           'provider' => \TYPO3\CMS\Core\Imaging\IconProvider\SvgIconProvider::class,
            // the source SVG for the SvgIconProvider
           'source' => 'EXT:my_extension/Resources/Public/Icons/mysvg.svg',
       'mybitmapicon' => [
           'provider' => \TYPO3\CMS\Core\Imaging\IconProvider\BitmapIconProvider::class,
            // the source bitmap file
           'source' => 'EXT:my_extension/Resources/Public/Icons/mybitmap.png',
       'myfontawesomeicon' => [
           'provider' => \TYPO3\CMS\Core\Imaging\IconProvider\FontawesomeIconProvider::class,
            // the fontawesome icon name
           'name' => 'spinner',
            // all icon providers provide the possibility to register an icon that spins
           'spinning' => true,


The TYPO3 Core ships three icon providers which can be used:

  • BitmapIconProvider – For all kinds of bitmap icons (GIF, PNG, JPEG, etc.)
  • SvgIconProvider – For SVG icons
  • FontawesomeIconProvider – For all icons which can be found in the fontawesome.io icon font

In case you need a custom icon provider, you can add your own by writing a class which implements the IconProviderInterface.

Using icons in your code

You can use the Icon API to receive icons in your PHP code or directly in Fluid.

The PHP way

You can use the IconFactory to request an icon:



namespace MyVendor\MyExtension;

use TYPO3\CMS\Core\Imaging\Icon;
use TYPO3\CMS\Core\Imaging\IconFactory;

final class MyClass
    private IconFactory $iconFactory;

    public function __construct(IconFactory $iconFactory)
        $this->iconFactory = $iconFactory;

    public function doSomething()
        $icon = $this->iconFactory->getIcon(

        // Do something with the icon, for example, assign it to the view
        // $this->view->assign('icon', $icon);

The Fluid ViewHelper

You can also use the Fluid core:icon ViewHelper to render an icon in your view:

{namespace core = TYPO3\CMS\Core\ViewHelpers}
<core:icon identifier="my-icon-identifier" size="small" />

This will render the desired icon using an img tag. If you prefer having the SVG inlined into your HTML (for example, for being able to change colors with CSS), you can set the optional alternativeMarkupIdentifier attribute to inline. By default, the icon will pick up the font color of its surrounding element if you use this option.

{namespace core = TYPO3\CMS\Core\ViewHelpers}

The JavaScript way

In JavaScript, icons can be only fetched from the Icon Registry. To achieve this, add the following dependency to your RequireJS module: TYPO3/CMS/Backend/Icons. In this section, the module is known as Icons.

The module has a single public method getIcon() which accepts up to five arguments:


| Condition: required | Type: string |

Identifier of the icon as registered in the Icon Registry.


| Condition: required | Type: string |

Desired size of the icon. All values of the Icons.sizes enum are allowed, these are: small, default, large and overlay.


| Condition: optional | Type: string |

Identifier of an overlay icon as registered in the Icon Registry.


| Condition: optional | Type: string |

Sets the state of the icon. All values of the Icons.states enum are allowed, these are: default and disabled.


| Condition: optional | Type: string |

Defines how the markup is returned. All values of the Icons.markupIdentifiers enum are allowed, these are: default and inline. Please note that inline is only meaningful for SVG icons.

The method getIcon() returns a jQuery Promise object, as internally an Ajax request is done.

The icons are cached in the local storage of the client to reduce the workload off the server. Here is an example code how a usage of the JavaScript Icon API may look like:

Here's an example code how a usage of the JavaScript Icon API may look like:

define(['jquery', 'TYPO3/CMS/Backend/Icons'], function($, Icons) {
    // Get a single icon
    Icons.getIcon('spinner-circle-light', Icons.sizes.small).done(function(spinner) {

Available icons

The TYPO3 Core comes with a number of icons that may be used in your extensions.

To search for available icons, you can use one of these possibilities:

Install styleguide extension

Install the extension styleguide as described in the Readme in the installation section.

Once, installed, you can view available icons by selecting help (?) on the top in the TYPO3 backend, then Styleguide and then Icons, All Icons.

There, browse through existing icons. Use the name under the icon (for example actions-add) as first parameter for IconFactory::getIcon() in PHP or as value for the argument identifier in Fluid (see code examples above).

Use TYPO3.Icons

An alternative way to look for existing icons is to browse through TYPO3.Icons.


The Rector rule \\Ssch\\TYPO3Rector\\Rector\\v11\\v4\\RegisterIconToIconFileRector can be used for automatic migration.

For manual migration remove all calls to \TYPO3\CMS\Core\Imaging\IconRegistry::registerIcon() from your EXT:my_extension/ext_localconf.php and move the content to Configuration/Icons.php instead.
