HTML Beautifier

HTML Beautifier reformats minified or poorly indented HTML into clean, readable markup with proper nesting. It's completely free and requires no sign-up, so you can tidy up a page's source in moments. Web developers debugging templates, students learning HTML structure, and anyone auditing a page's markup will find it genuinely useful.

What is HTML Beautifier?

When HTML is minified or generated by a content management system, tags often end up crammed onto a single line with no indentation to show parent-child relationships. This tool reformats the markup with consistent indentation for each nested element, making it far easier to spot unclosed tags or misplaced elements. It's a common first step when inspecting a competitor's landing page or debugging a rendering issue in your own templates.

Frequently asked questions

Is HTML Beautifier free?

Yes, this tool is free to use with no sign-up or hidden fees. You can beautify unlimited HTML documents.

Does beautifying change how the page renders?

No, reformatting only adds whitespace and indentation, so the page renders exactly the same in a browser. Only the readability of the source code changes, not its behavior.

Can it fix broken or invalid HTML?

The tool focuses on formatting rather than validating markup, so it won't automatically correct unclosed tags or invalid nesting. However, the added indentation often makes such errors much easier to spot yourself.

Is this different from viewing page source in a browser?

Yes, most browsers show HTML source largely as-is, without reformatting minified or compressed markup for readability. This tool specifically reindents that raw source so nested elements are easy to follow.
