About HTML Beautifier

This HTML beautifier takes minified or poorly formatted HTML and adds proper indentation and line breaks for readability. It recognizes void elements (like <br>, <img>, <input>) that don't need closing tags, preserves content inside <script>, <style>, and <pre> tags, and handles self-closing tags. The minify mode removes comments, collapses whitespace, and strips unnecessary spaces between tags to reduce file size. Use it to clean up HTML from email templates, CMS exports, or View Source output.

Frequently Asked Questions

Does it preserve script and style content?
Yes. Content inside <script>, <style>, <pre>, and <textarea> tags is preserved as-is and not reformatted. These tags often contain content where whitespace matters.
What is the difference between beautify and minify?
Beautify adds indentation and line breaks to make HTML readable. Minify removes comments, extra whitespace, and line breaks to reduce file size — useful for production deployment.
Does it handle self-closing tags?
Yes. Void elements like <br>, <hr>, <img>, <input>, <meta>, and <link> are recognized and don't add extra indentation. Self-closing syntax like <br /> is also supported.
