A free, browser-based HTML editor built for developers, designers, content writers, and SEO^[1] professionals. Write your HTML, CSS, and JavaScript in one place — see the live output in real time, no setup required.

• Live Preview See your HTML render in real time as you type. The split-screen layout keeps your code and output side by side so you can spot issues instantly — no need to refresh or switch tabs.
• HTML, CSS & JS Support Write complete web code in one place. The editor supports HTML structure, CSS styling, and JavaScript logic — giving you a full front-end playground in a single browser window.
• One-Click Copy Done with your code? Copy it to your clipboard with a single click and paste it directly into your CMS, email builder, or codebase.
• Export Your Work Download your finished HTML file with the Export button. Great for saving templates, sharing code snippets, or archiving your work locally.
• Format & Clean Code Use the Format button to auto-indent and clean up messy or minified HTML, making your code easier to read, edit, and share.
• Full-Screen Mode Toggle full-screen for a distraction-free coding environment — ideal when working on larger templates or presentations.
• Character & Line Counter Track your code length in real time with the built-in character and line counter — useful for keeping email HTML within size limits or monitoring snippet length.

Unlike heavyweight IDEs or paid tools, the WDG HTML Online Editor is purpose-built for speed and simplicity. It runs entirely in your browser, loads instantly, and gets out of your way so you can focus on building.
