Professional HTML Formatting for Developers

When dealing with complex web projects, HTML code can quickly become unreadable due to nested tags, lack of indentation, or automated code generation. Our online HTML formatter uses advanced parsing algorithms to restore structure and readability to your markup instantly.

Whether you're debugging a layout issue or preparing code for production, this tool provides the flexibility to beautify (expand with indentation) or minify (compress for performance) your HTML with a single click.

One-Click Minification

Frequently Asked Questions

Will it break my CSS or JS?

No. The formatter is aware of `<style>` and `<script>` blocks and preserves their internal structure while formatting the surrounding HTML.

Is there a limit on file size?

We support HTML files up to several megabytes. For extremely large files, we recommend using a CLI tool, but for most web development needs, this tool is sufficient.

Can I use this for XML?

While primarily designed for HTML, this tool works well for most XML structures due to their shared tag-based syntax.

What is Minification?

Minification removes all unnecessary characters (like spaces and line breaks) without changing functionality, helping your website load faster.
