About HTML Formatter

The HTML Formatter takes messy, minified, or poorly indented HTML and produces clean, properly nested output. It is useful for debugging templates, reviewing HTML from external sources, and making code more readable before editing.

Features

  • Proper indentation — Nests child elements under their parents.
  • Inline element handling — Keeps inline elements like <span>, <a>, <strong> on a single line.
  • Configurable indent — Choose 2 spaces, 4 spaces, or tab indentation.
  • Copy to clipboard — One click to copy the formatted result.

How to Use

  1. Paste your HTML (compressed or unformatted) into the input area.
  2. Click Format — the properly indented HTML appears in the output.
  3. Choose the Indentation style (2 spaces, 4 spaces, or tabs).
  4. Click Copy to copy the formatted HTML.

How It Works

The tool parses HTML tokens (open tags, close tags, self-closing tags, text, comments) and rebuilds the document with consistent indentation. Block-level elements are placed on new lines; inline elements may remain on the same line depending on context.

Example

Paste a minified HTML template from an email or CMS and format it to readable, editable markup in one click. Useful for debugging generated HTML or reviewing code before editing.

FAQ

No — this tool focuses on formatting and indentation, not validation. It will format whatever HTML you provide even if it contains errors.
No. All formatting runs entirely in your browser using JavaScript. Your code is never transmitted anywhere.
