What is an HTML Formatter?
An HTML formatter (or beautifier) takes unformatted, minified, or messy HTML and re-indents it with consistent whitespace and proper nesting to improve readability. It is essential for debugging, code review, and working with generated or minified templates. The minify mode does the reverse — strips whitespace and comments to produce compact HTML for production use.
How to Use the HTML Formatter
- Paste your HTML into the input field.
- Choose Beautify to indent or Minify to compress.
- Click Format or press Ctrl+Enter.
- Open Advanced to set indent size (2 spaces, 4 spaces, or tab) and toggle comment preservation.
- Click Copy to copy the result.
When to Use This Tool
Use for debugging minified HTML, formatting template output, preparing code for documentation, or compressing HTML for production. For JSON beautification, use the JSON Formatter. For CSS and HTML entity encoding, see the HTML Encode / Decode tool.
Frequently Asked Questions
What does an HTML formatter do?
An HTML formatter takes unformatted or minified HTML and re-indents it for readability. It adds proper nesting, whitespace, and line breaks.
What is HTML minification?
Minification removes all unnecessary whitespace, comments, and line breaks from HTML to reduce file size for faster page loads.
Is my HTML sent to a server?
No. All formatting and minification runs entirely in your browser. Your code is never uploaded or stored.
