# Core link handler {#core-link-handler}

The Core link handler, implementing the
`\TYPO3\CMS\Core\LinkHandling\LinkHandlingInterface` described here
matches between different internal representations of a link. It is not
to be mixed up with the [backend link handler](https://docs.typo3.org/permalink/t3coreapi:linkhandler@14.3), commonly
also just called link handler. The latter implements the
`\TYPO3\CMS\Backend\LinkHandler\LinkHandlerInterface` and renders a
tab in the link browser.

You can find the built-in Core link handlers in
`EXT:core/Classes/LinkHandling`.

In the tutorial section we provide an example on how to implement a
[custom Core link handler](https://docs.typo3.org/permalink/t3coreapi:tutorial-core-link-handler@14.3).
