Remove formatting

The remove format feature lets you quickly remove any text formatting applied using inline HTML elements and CSS styles, like basic text styles (bold, italic) or font family, size, and color. This feature does not remove block-level formatting (headings, images) or semantic data (links).

# Demo

Select the content you want to clean up and press the remove format button in the toolbar.

# Installation

After installing the editor, add the feature to your plugin list and toolbar configuration:

import { ClassicEditor, RemoveFormat } from 'ckeditor5';

ClassicEditor
    .create( document.querySelector( '#editor' ), {
        plugins: [ RemoveFormat, /* ... */ ],
        toolbar: [ 'removeFormat', /* ... */ ]
    } )
    .then( /* ... */ )
    .catch( /* ... */ );

# Configuring the remove format feature

This feature has no integration–level configuration. Once enabled, it works out–of–the–box with all core editor features.

# A short note about content types in the editor

The remove format feature is intended to help users tidy up chunks of content from unnecessary formatting. Each editor feature brings its own content types to the WYSIWYG editor. If you do not want the unnecessary formatting to be enabled in the first place, you may want to consider reducing the number of features enabled in the editor.

Doing that will spare the users the pain of manually removing formatting every time they paste content from other programs and make the editing experience smoother. The narrower set of editor features also gives you more control over the content saved to the database and prevents the accidental use of the types of content you would rather not store in your application.

# Integrating with editor features

In order for the remove formatting feature to work with custom content, you need to update the schema by setting the isFormatting property on the custom text attribute.

This is already done for most inline elements supported by the General HTML Support plugin and its derivatives such as the Style plugin.

By default, formatting is not removed from the link elements. To remove formatting from them as well, you need to create a plugin that extends the schema and tells the editor that the linkHref text attribute produced by the link feature is a formatting attribute:

// A simple plugin that extends the remove format feature to consider links.
function RemoveFormatLinks( editor ) {
    // Extend the editor schema and mark the "linkHref" model attribute as formatting.
    editor.model.schema.setAttributeProperties( 'linkHref', {
        isFormatting: true
    } );
}

Enable the RemoveFormatLinks plugin in the configuration and run the editor:

ClassicEditor
    .create( document.querySelector( '#editor' ), {
        plugins: [
            RemoveFormat,
            RemoveFormatLinks,
            // More plugins.
            // ...
        ],
        toolbar: [
            'removeFormat',
            // More toolbar items.
            // ...
        ]
    } )
    .then( /* ... */ )
    .catch( /* ... */ );

From now on, the remove format button should also remove links in the content. Learn more about attribute properties.
