Formatted or Minified HTML

Format or Minify HTML Markup

Paste compressed or messy HTML and format it with readable indentation, or minify markup by removing extra whitespace for compact embedding.

Review Complex Markup Carefully

Formatting can make nested tags easier to debug, but email HTML, SVG, inline scripts, and template syntax may need manual review after cleanup.

When HTML Formatting Helps

Use it before editing landing page sections, CMS snippets, newsletter blocks, documentation examples, reusable components, and legacy markup copied from builders.

Overview

HTML Formatter takes minified or poorly indented HTML and outputs it with consistent nesting, proper tag structure, and readable whitespace. It also validates the markup and highlights unclosed or mismatched tags.

Good Times to Use It

Use this when reviewing a page's source HTML that was minified in production, when debugging a template with deeply nested elements, or when preparing HTML for a code review.

How to Use

Paste your HTML into the input area.
Click Format to apply indentation and structure.
Review any warnings about invalid nesting.
Copy the formatted HTML.

Questions People Ask

Does formatting change how the browser renders the page?

No. Formatting only changes whitespace and indentation, which has no effect on browser rendering.

Can it fix invalid HTML?

The formatter reports common errors but does not automatically fix structural issues. Review the warnings and correct them manually.

Does it support HTML5 elements?

Yes. Modern elements including section, article, nav, header, footer, main, and template are all recognised correctly.
