Syncfusion Rich Text Editor SDK is a content editing package for building rich text and block-based authoring experiences. Its components support WYSIWYG editing, formatting, media, tables, customizable toolbars, smart editing features, real-time collaboration on supported platforms, AI-assisted authoring, document import and export, and content sanitization.

Create Rich Text Content

Build What You See Is What You Get (WYSIWYG) editing experiences where users can create and modify formatted content directly. Apply fonts, colors, styles, alignment, lists, links, and text decoration to support structured authoring within content-driven applications.

Build Block-Based Editing Experiences

Organize content using block-based editing for structured authoring and flexible content arrangement. Users can create and manage distinct content sections while applications provide an editing environment suited to documents, articles, knowledge content, and other structured writing workflows.

Customize Editing Toolbars

Add, remove, and rearrange toolbar actions according to application requirements. Configure expanded, multirow, scrollable, pop-up, or responsive toolbars, and add custom buttons for application-specific commands alongside formatting, media, table, and link actions.

Insert and Manage Rich Media

Embed images using file uploads or Uniform Resource Locator (URL) input, then resize and align them within edited content. Media capabilities allow applications to combine formatted text and visual elements within the same authoring experience.

Create and Edit Tables

Insert tables directly within rich content and modify their structure and presentation during editing. Users can resize, merge, and style table elements, supporting content that requires organized rows and columns alongside text, links, images, and other elements.

Use Smart Editing Features

Provide slash commands, @mentions, an emoji picker, a format painter, Markdown shortcuts, undo and redo, and contextual quick toolbars. These capabilities give users direct access to common editing actions while they create and revise content.

Collaborate on Content in Real Time

Enable multiple users to write, edit, and update shared content simultaneously on supported platforms. Synchronized changes support collaborative authoring scenarios where teams need to work together within the same content editing experience.

Add AI-Assisted Authoring

Integrate supported artificial intelligence (AI) capabilities for generating, rewriting, summarizing, translating, and improving content directly within the editing experience. Availability varies by editor and platform, allowing applications to add intelligent writing assistance where supported.

Import, Export, and Clean Content

Import Word documents while preserving supported formatting, and export edited content to Word or Portable Document Format (PDF). Paste cleanup removes unwanted styles, scripts, and markup from external content to maintain more consistent formatting within the editor.

Protect and Validate Edited Content

Sanitize user input to help prevent cross-site scripting (XSS) through malicious scripts and unsafe content. Built-in validation and content handling capabilities support applications that need greater control over the information users create, paste, and modify within editing interfaces.
