What is an HTML Viewer?
An HTML viewer (also called an HTML editor or HTML previewer) is a development tool that lets you write or paste HTML code and immediately see how it renders in a browser. It's essential for web developers, designers, students, and anyone learning HTML.
Unlike a full IDE, an online HTML viewer is lightweight, instant, and works directly in your browser. There's nothing to install, no accounts to create, and no configurations to set up — just open the page and start coding.
