About HTML Beautifier

Messy, minified, or inconsistently indented HTML is one of the most common frustrations in web development. Xevon Tools' HTML Beautifier takes any HTML — whether it is compressed for production, scraped from a website, or generated by a CMS — and applies proper indentation with consistent line breaks at every nesting level. The result is clean, readable markup that makes structure and hierarchy immediately obvious. A companion minify mode strips all unnecessary whitespace and comments to produce the smallest possible output for production use. Both modes are available from the same interface with a single toggle. The tool handles large documents without performance issues and runs entirely in your browser, so your code is never sent to a server. Whether you are debugging a production page, reviewing scraped content, or standardizing formatting across a team, this tool makes HTML readable in seconds.

Frequently asked questions

Yes. The tool has both a Beautify mode (adds indentation and line breaks) and a Minify mode (strips whitespace and comments for production). Switch between them with a single toggle.
The tool formats the structure of the HTML you provide but does not validate or repair broken markup. Missing closing tags or invalid nesting will be formatted as-is.
The default is 2-space indentation, which is the most common convention for HTML. The formatting produces consistent, readable output for any nesting depth.
No. All formatting happens in your browser using a client-side library. Your HTML code is never transmitted to a server.
