A WYSIWYG editor — "What You See Is What You Get" — is a tool that lets you edit content by working directly with a visual representation of the final output, instead of editing raw code. When applied to HTML, a WYSIWYG editor shows you the page as it will actually render, and lets you change it by clicking and typing directly on that rendered view.
What does WYSIWYG mean?
The acronym dates back decades, originally coined for early word processors and desktop publishing tools that showed formatted text on screen instead of formatting codes. The core idea hasn't changed: what you see while editing should closely match what you get in the final result. Applied to HTML, that means you see the actual heading, paragraph, or image — not the <h1> or <img> tag that produces it.
How does a WYSIWYG editor work?
Under the hood, a WYSIWYG HTML editor still has to manage real markup — the tags, attributes and structure that make up the page. The difference is that it handles that markup for you. When you click a headline and type a new sentence, the editor updates the underlying <h1> element's content automatically. When you drag an image into place, it updates the corresponding <img> tag. You interact with the visual page; the editor keeps the HTML in sync behind the scenes.
Not every WYSIWYG tool works identically — some are built into larger platforms with their own constraints, others are focused specifically on editing a standalone HTML file — but the underlying principle is the same: visual editing, real markup underneath.
WYSIWYG vs HTML code editor
A code editor (like VS Code, Sublime Text, or a plain text editor) shows you the raw tags and expects you to write or modify them directly. This gives you complete, precise control, but it requires understanding HTML syntax: knowing that a <div> needs a closing </div>, that attributes need quotes, that a stray character can silently break the layout.
A WYSIWYG editor removes that syntax layer entirely. You never see a tag. This trades some precision for speed and accessibility — which matters most depends entirely on who's editing and what they're trying to do. Someone comfortable with code, making a structural change, may prefer the code editor. Someone who just needs to fix a headline or swap a photo almost always prefers the visual view.
WYSIWYG vs website builder
These get confused often, but they solve different problems. A website builder — think of the large hosted, all-in-one platforms — is a complete environment for building and hosting a site from scratch: templates, drag-and-drop page building, hosting, domains, all bundled together. You build inside their system, and your site typically lives on their infrastructure.
A WYSIWYG HTML editor, by contrast, can be a much more focused tool: you bring an existing .html file — one your AI assistant already generated, for example — and you edit it visually, without being locked into a hosting platform or a proprietary template system. The output is still just a portable HTML file (or a PDF), not a site tied to one vendor.
Visual HTML editing explained
Applied specifically to HTML files, visual editing means: you open a file, the editor renders it exactly as a browser would, and you click directly on any text, image or element to change it in place. There's no separate "preview" step, because what you're editing is the preview. This is a meaningfully different workflow from traditional HTML editing, where you'd write code in one window and check the result in another, going back and forth between the two.
When should you use a WYSIWYG editor?
A WYSIWYG editor is the right tool when the content of an existing page needs to change — text, images, small layout tweaks — and preserving the page's existing structure and styling matters. It's especially useful when the person making the change isn't a developer and shouldn't need to become one just to fix a typo or swap an image.
When is direct HTML editing better?
Direct code editing still wins when you're building something new from scratch, need fine-grained control over markup structure, or are integrating the page with other systems (a CMS, a build pipeline, custom scripting). WYSIWYG tools are built for refining what already exists, not architecting something new.
WYSIWYG editors in the age of AI
The rise of AI-generated HTML has given WYSIWYG editors a new, specific job. Tools like Claude and ChatGPT can produce a complete, well-structured HTML document from a plain-language prompt in seconds — see why HTML has become the default output format for AI — but the result is rarely exactly right on the first try. A headline needs sharpening, a number needs updating, an image needs replacing. That's finishing work, not building work, and it's exactly what a WYSIWYG editor is designed for: taking a strong AI-generated draft and making it yours, visually, without opening a single tag.
FAQ
What does WYSIWYG mean?
"What You See Is What You Get." It describes any editor where you work with a visual representation of the finished output, rather than editing raw code or markup, and what you see while editing closely matches the final result.
Is a WYSIWYG editor the same as a website builder?
Not necessarily. A website builder is usually a complete hosted platform for building a site from scratch, with templates, hosting and its own ecosystem. A WYSIWYG HTML editor can be a more focused tool for opening and editing an existing HTML file, with no platform lock-in.
When should I edit HTML directly instead of using a WYSIWYG editor?
When you need precise control over the markup itself, such as adding custom behavior, integrating with other systems, or building something structurally new. For refining content, text and layout on an existing page, a WYSIWYG editor is faster and doesn't require coding knowledge.
Are WYSIWYG editors still relevant now that AI can write HTML?
Yes, arguably more relevant than before. AI assistants generate the HTML structure quickly, but a person still needs to review, correct and personalize the result. A visual editor is the natural place to do that finishing work without touching code.
