Paste minified or messy HTML into the left input panel.

Click Format HTML

The formatter indents and structures your HTML with proper nesting and line breaks.

Copy or download

Copy the formatted HTML or download it as an .html file.

Does it validate HTML as well?+

The formatter fixes indentation and structure but does not validate against the HTML spec. Use the W3C validator for full validation.

Will it break my HTML?+

No. The formatter only adds whitespace and indentation. It does not modify attributes, tag names, or content.

Does it support HTML5?+

Yes. All HTML5 elements and void elements like br, img, input are handled correctly.

Can I format very large HTML files?+

Yes. There is no size limit though very large files may take a moment to process.
