About this html formatter & beautifier

The HTML formatter turns compressed or messy markup into a readable structure with predictable indentation. It is best for reviewing copied DOM fragments, email templates, CMS snippets, or generated static markup before making manual changes.

Common uses

  • Review markup copied from browser dev tools.
  • Tidy email templates, CMS embeds, and static snippets.
  • Make generated HTML easier to compare during QA.

Practical notes

Formatting HTML does not sanitize it, so untrusted markup should still be reviewed before it is rendered.

Keep inline elements and whitespace-sensitive content in mind when copying formatted markup back into templates.

Frequently Asked Questions

What is HTML formatting?

HTML formatting adds proper indentation and line breaks to compressed HTML, making the document structure easy to read and understand.

Are inline elements handled differently?

Yes. Inline elements like <span>, <a>, <strong>, <em>, etc. are kept on the same line as their surrounding text, while block elements like <div>, <p>, <h1>, etc. get their own indented lines.
