HTML Formatter

Format and beautify HTML code for better readability. Free online HTML formatter that works in your browser.

Everything runs in your browser. Your input is not sent to a server. Previews run in an isolated sandboxed frame and only when you press Run Preview.

How to use the HTML Formatter

  1. Paste your HTML markup.
  2. Run Format / Beautify.
  3. Copy the indented result.
  4. Fix any structural issues if the formatter reports problems.

How it works

Tags are indented to reflect nesting depth so structure is easier to scan. The tool does not execute scripts; it only reformats markup text.

Helpful when cleaning exported HTML or reviewing templates.

Examples

  • A single-line <div><p>Hi</p></div> becomes nested, indented lines.
  • Attributes stay on their tags; whitespace between text nodes may be normalized.
  • Malformed HTML may format incompletely until tags are balanced.

Does formatting change how the page looks?

Browser rendering ignores most extra whitespace in HTML, so visual layout should stay the same for typical markup.

Is script content executed?

No. This is a text formatter only.

Is the HTML Formatter free?

Yes.
