HTML Formatter & Minifier
Beautify nested HTML, compact snippets for transport, and catch common unbalanced tag mistakes before copying output.

HTML output
Formatted or minified HTML output
Paste HTML, then choose Format HTML or Minify HTML.
Sample input and expected output

The formatter checks for missing and mismatched closing tags before serializing the HTML fragment.
What this HTML Formatter does
Use this HTML formatter and minifier to clean up HTML snippets, check balanced tags, or compact markup. It is built for developers reviewing copied templates, CMS snippets, and payload examples.
When developers use it
- Beautify HTML snippets before documentation, code review, or debugging.
- Minify small HTML fragments for embedding or transport.
- Catch unbalanced tags before copying markup into another system.
Privacy, input, and output
HTML formatting runs locally in the browser. PayloadHarbor does not upload markup snippets.
Paste HTML and choose Format or Minify. Valid output can be copied or downloaded as an HTML file.
Validation rules and limitations
- The checker is intended for snippets and balanced-tag feedback, not full browser rendering validation.
- It does not execute scripts or fetch external assets.
