View, inspect, and explore HTML source code online. Get syntax highlighting, formatting, and a readable view of any HTML document or snippet.
An HTML viewer lets you open, read, and navigate HTML source code with syntax highlighting and automatic formatting. Instead of scrolling through minified HTML or raw server output, a viewer makes the structure immediately understandable by revealing nesting, attributes, and content in a clean, colour-coded layout.
JSON Viewer Pro's HTML viewer is built on Monaco Editor, the same engine as Visual Studio Code. It provides full HTML syntax highlighting with distinct colours for tags, attributes, strings, and comments. The editor folds deeply nested structures so you can focus on the parts you care about. You can search for specific elements, attributes, or text values across the entire document using Monaco's powerful Find functionality.
The HTML viewer is useful for inspecting rendered HTML from browsers (copy from DevTools), email template HTML, CMS page HTML, and HTML files from any source. All viewing is local — no HTML is sent to any server.
Not directly. Copy the page source (View Source in your browser or DevTools) and paste it into the viewer.
Yes. The viewer is also an editor — you can make changes and download the updated HTML.
No. The viewer shows the HTML source code with syntax highlighting, not a rendered visual preview.
