The Basics

What Is an HTML Editor?

An HTML editor is a software application or browser-based tool for writing and editing HTML, the code that structures every web page. It adds helpers such as syntax highlighting, auto-completion and a live preview, so you can see how your page looks while you type. FreeHTMLEditor.net is a free online HTML editor: it runs in your browser, with nothing to install and no sign-up.

⌨️

Code editors

Show the raw HTML so you type every tag yourself, with full control. Examples: Visual Studio Code, Sublime Text, Notepad++.

🎨

Visual (WYSIWYG) editors

Design the page visually, like a word processor, and the editor writes the HTML. Examples: Dreamweaver, the WordPress block editor.

🌐

Online editors

Run in your browser with a live preview, ideal for learning and quick tests. Examples: FreeHTMLEditor.net, CodePen, JSFiddle.

How to use the free HTML editor, step by step

  1. Open the editor. Click Open Editor; it loads in your browser with example files ready, and there’s nothing to install or sign up for.
  2. Pick or create a file. Open an example from the file tree, choose a ready-made design from Templates, or click + New for a blank HTML file.
  3. Write your HTML, CSS and JavaScript. Syntax highlighting and smart indentation keep the code readable, and you can open several files in tabs.
  4. Watch the live preview. The preview pane updates as you type. Drag the dividers to resize the panes, or switch between the editor-only, editor + preview and 3-pane views.
  5. Test on other screen sizes. Use the Desktop, Tablet and Mobile buttons, or Open tab to view the page full-size in a new browser tab.
  6. Save, export or share. Your files save automatically in this browser; click Export to download the file, or Share to copy a link that opens your code for anyone.

Why Online

Why Use an Online HTML Editor?

Desktop code editors are great for big projects, but for learning, testing and quick pages an online editor is faster.

  • Start in seconds. No downloads, installs or extensions — open the page and type.
  • See results instantly. The live preview replaces the save-and-refresh cycle of a desktop editor.
  • Use any computer. Windows, Mac, Linux or Chromebook: if it has a modern browser, it works.
  • Stay private. Your code runs in your own browser and is never sent to our servers.
  • Check mobile layouts. Switch between desktop, tablet and phone sizes with one click.
  • Learn as you go. Every tag in the HTML reference has a live example that opens straight in the editor.
