What is a WYSIWYG Editor?

A WYSIWYG editor lets you edit a web page in a view that closely resembles what visitors will see. Drag-and-drop website builders are one common example; the rich text editors inside a CMS, like WordPress’s visual editor, are another. Either way, you work on the rendered page directly instead of writing code and previewing it separately.

Visual controls let you format content without memorizing HTML and CSS or switching between the back end and the front end. They don’t catch everything, though: a WYSIWYG editor won’t flag broken links, inaccessible color contrast, or a layout that fails on smaller screens. Preview and test the page before publishing.

How a WYSIWYG editor works

The editor renders your page close to how a browser will display it, while writing the underlying HTML and CSS for you in the background. Every visual action maps to a code change: dragging a section rearranges the markup, and bolding a word wraps it in a formatting tag. Most editors also offer a code view, so you can inspect or edit the markup the tool produced when the visual controls fall short.

Kinds of WYSIWYG editors, with examples

In web work, you’ll run into 2 kinds:

• Embedded content editors: the rich text fields inside a CMS, email platform, or forum. You type and format with a toolbar, the way you would in Google Docs. TinyMCE, CKEditor, and WordPress’s visual editor are well-known examples.
• Website builders: drag-and-drop tools that lay out entire pages, not just the content inside them. You place sections, images, and buttons on a canvas, and the builder generates the page.

Drag-and-drop is one interaction style, not the definition. Whether you’re dragging sections in a builder or bolding text with a toolbar, the WYSIWYG part is the same: you edit the rendered result directly. For a deeper look at the builder side, see our guide to website builders in 2026.

Limitations of WYSIWYG editors

The convenience has 3 concrete costs:

• Heavier code: generated markup is often bulkier than what a developer would write by hand, which can slow page loads.
• Preview drift: the editing view is a close preview, not a guarantee. Themes, browsers, and screen sizes can all shift what visitors actually see.
• Lock-in: a design built inside one builder is hard to move elsewhere, because the layout lives in that tool’s format.

So preview the published page on a phone before you call it done, and if you know you’ll need custom features, weigh that before committing to a builder.

When to use a WYSIWYG editor instead of code

• Use a WYSIWYG editor when you need a standard site, like a brochure site, blog, or portfolio, online fast without coding.
• Use a code editor, or your WYSIWYG tool’s code view, when you need custom functionality, performance-tuned markup, or a design the builder’s blocks can’t produce.

In practice, the 2 approaches mix. A builder plus a little custom CSS is a common workflow, and WordPress pairs its visual editor with a text editor for exactly that reason.
