Paste HTML and format it
Use this for readability, indentation, and before/after review. It is not a full HTML validator, so still review malformed markup before production use.
What the formatter handles
- Nested tags with line breaks and indentation
- HTML comments, doctype, and common void elements such as br, img, and input
- Raw content inside script, style, and pre tags
- Copied snippets, component markup, and full body fragments
Where this tool fits
HTML formatter intent is usually not tutorial-first. Users already have pasted markup and want a faster way to inspect nesting and spacing, then compare revisions or copy clean output.
Formatter vs validator
This page makes HTML easier to read. It does not prove that the markup is valid, accessible, or safe to ship. If a browser is repairing broken nesting automatically, compare the formatted output with the original snippet and review the surrounding template before using it.
FAQ
No remote formatting service is required for the core formatter flow. The tool is designed to run in your browser.
Yes. Content inside script, style, and pre tags is preserved instead of being reformatted as normal text nodes.
No. It is a formatter and beautifier. Use it to inspect structure and indentation, then manually review invalid nesting, missing attributes, or accessibility issues.
