What is a Rich Text Editor?

A rich text editor (RTE) is a text input field where users format content visually: bold, italics, headings, lists, embedded images, and videos. A standard HTML <textarea> only accepts plain text. A code editor highlights syntax but doesn't render it. An RTE does neither. It gives users a word-processor-style surface for creating and managing formatted content, right in the browser. And 71% of developers find RTEs critical for their apps.

Rich text editor vs. plain text editor vs. code editor

Here are the main differences between a plain text editor, rich text editor, and code editor. All of them look like a box where you type, but they are very different. 

A plain text editor strips formatting out entirely, so every character you type is just raw content, no bold, no headings, no structure. 

A rich text editor goes beyond simple text input and builds a formatting layer on top of that same box: Links, images, styled text, the visual structure a reader actually sees. 

A code editor throws formatting out altogether and replaces it with syntax awareness: Indentation, bracket matching, and autocomplete tuned to a programming language instead of prose.

Rich text editor vs. WYSIWYG

Rich text and WYSIWYG get used interchangeably, but they answer different questions.

Rich text describes what the editor produces: styled, structured content instead of plain text, like an article, a support ticket, or a lesson in an online course.

WYSIWYG (which stands for “what you see is what you get”) describes how the editor shows you that content while you're working. You see a live, on-screen preview of the finished output as you edit, with no separate render or compile step standing between the two. Not every rich-text approach works this way. Markdown produces rich text too. It just skips the live preview: you write syntax, then render it separately.

Most modern rich text editors, TinyMCE included, do both jobs at once. TinyMCE is a robust rich text editor with 1.5 million global users: An open source core, true WYSIWYG rendering, and official support for React, Vue, and Angular.

How rich text editors work

Under the hood, an RTE translates a user's formatting choices into HTML as they type. Click "bold," and the editor wraps the selection in <strong> tags. The visual change and the markup happen at the same time.

Most modern RTEs, TinyMCE included, build this on a browser's native contentEditable API, which turns a regular Document Object Model (DOM) element into an editable surface. The editor's job is everything layered on top of that surface: The toolbar, the paste handling, the schema that keeps users from generating broken or unsafe markup. Writers get to think in formatting; the RTE thinks in HTML on their behalf.

The best rich text editors in 2026

Every RTE on the market has a different take on architecture and control. Here's how the four most common choices stack up.

Some rich text editors ship as full-featured and ready-to-configure, while others are headless frameworks with no UI of their own. Licensing varies as well, from TinyMCE’s free-forever open core to closed source like Froala. Editors with enterprise solutions generally provide dedicated support and customer service teams.

Framework support ranges from broad compatibility across a dozen-plus frameworks (TinyMCE) to a narrow, framework-agnostic core built to sit inside anything (Froala). TinyMCE, CKEditor 5, Froala, and Tiptap each land in a different spot on all three. Check out the list of the best React rich text editors to read more about framework compatibility. 

Security and accessibility are critical for any RTE

An RTE does two things a plain <textarea> never has to:

1. It generates real markup from user input.
2. It replaces a native form control with a custom-built, interactive widget.

Those two facts are where the risk sits. The first is a security challenge. The second is an accessibility concern.

Security

The moment an RTE accepts rich text, it's accepting user-generated HTML, and unsanitized HTML is a possible XSS attack vector. A production-ready RTE sanitizes input, filters output, and lets you configure exactly which tags and attributes are allowed. That's a property of the editor's configuration and the vendor's practices, not something that comes with choosing "rich text" over "plain text" automatically.

Accessibility

Screen reader support, keyboard navigation, and WCAG 2.2 compliance sit right next to security on most procurement checklists now, especially for education and enterprise buyers. An RTE that looks fine visually but breaks for keyboard-only or assistive-tech users is going to fail reviews, no matter how good its formatting toolbar is.

Rich text editor frameworks

Framework fit is usually the first practical filter: It decides how much glue code you're writing before you get to the parts users actually see. Most editors support multiple frameworks, and many have native support or wrappers for framework compatibility.

TinyMCE ships official components for all three major frameworks, so "does this work with our stack" doesn't have to be the thing that decides your editor. Framework integration shouldn't be a bottleneck for adding your rich text editor to your web apps.

Advanced rich text editor features

Beyond the normal editing experience using functionality like bold, italics, or lists in a rich text editor, there are many advanced features available in multiple editors. For example, many rich text editors include some form of collaborative editing, AI chat, AI review, and revision history in their plugin system. These pre-built extensions remove the need for your engineering team to build advanced functionality from scratch. 

Other editors require building custom UI components, toolbar buttons, and require engineering editor behavior, but that does allow developers complete control of their rich text editor.

Advanced formatting, various output formats, a Microsoft Word-like document experience-All of these features and customization are how an RTE evolves into a tailor-made user experience that fits into your specific app.

How to choose a rich text editor

Skip the feature list for a second, and check which of these actually describe your situation:

• Your users are non-technical and expect a word-processor-style experience.
• Security and accessibility compliance are real requirements, not nice-to-haves.
• You'd rather not own the editor's long-term maintenance yourself.

If most of these are true, you're looking for a mature, configurable editor. Not a lightweight embed, and not a framework you build on top of. The right choice matches your actual requirements list.

Setting up TinyMCE

Getting a first instance running takes one index.html file:

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <script src="https://cdn.tiny.cloud/1/no-api-key/tinymce/8/tinymce.min.js" referrerpolicy="origin" crossorigin="anonymous"></script>
    <script>
      tinymce.init({
        selector: '#mytextarea'
      });
    </script>
  </head>
  <body>
    <h1>TinyMCE Quick Start Guide</h1>
    <form method="post">
      <textarea id="mytextarea">Hello, World!</textarea>
    </form>
  </body>
</html>

That script tag loads TinyMCE 8 from the CDN. tinymce.init() turns the textarea into a full rich text editor. Open the file in a browser and it's already running. Swap no-api-key for a free TinyMCE API key to use on your own domain without the reminder banner, and you get a 14-day trial of the premium plugins along with it. You can try TinyMCE self-hosted or with Tiny Cloud.

TinyMCE is open source

The core TinyMCE editor is open source and free. It also has over 16,000 GitHub stars and more than a million npm downloads a week. For most applications, the open source edition covers everything you need. Teams that outgrow it move to premium plugins for things like advanced collaboration, TinyMCE AI, or compliance features.

Wrap up: What next?

The editor you pick should fit the requirements you actually have, not the ones you guessed at when the field was "just a comment box." If you want the next layer of this, what WYSIWYG really guarantees and where it can quietly fall short, read our breakdown of WYSIWYG editors next.

FAQ

What is the best free rich text editor?

"Best" depends on your stack and requirements, but TinyMCE is one of the most widely used free and open source options, suited to many different use cases. TinyMCE is used in content management systems, learning management systems, SaaS applications, document management systems, and more. 

What's the difference between WYSIWYG and a rich text editor?

Rich text describes the formatting capability. WYSIWYG describes whether you see a live preview while you edit, or write syntax that renders separately later. Most modern rich text editors like TinyMCE do both.

Is TinyMCE free for commercial use?

Yes. The open source core is free forever, including for commercial projects. Premium plugins are a separate, optional layer.

What rich text editor does Google Docs use?

Google Docs runs on its own proprietary editing engine, not a third-party embeddable editor like TinyMCE or CKEditor.

How do I add a rich text editor to React?

Install TinyMCE's React component and initialize it in place of a <textarea>. See the React integration guide for the full setup.

Are rich text editors secure?

Not automatically. Security comes from how the editor sanitizes input and filters output, a configuration and vendor-practice question, not a property of the "rich text editor" category itself.
