HTML Formatter & Beautifier
Beautify and minify HTML online. Format messy HTML with proper indentation or compress it for production.
What is HTML Formatting?
HTML formatting (beautifying) takes compressed or inconsistently indented HTML and restructures it with proper nesting and indentation. This is essential for reading, debugging, and reviewing HTML documents, especially when working with minified output from build tools.
HTML minification removes all whitespace between tags, reducing file size and improving load times. Most production web servers or build pipelines minify HTML automatically.
How to Use
- Paste your HTML or upload an .html file
- Choose Beautify or Minify mode
- Adjust indent size in Settings
- Copy or download the formatted result
Frequently Asked Questions
Does formatting affect HTML rendering?
No. HTML parsers ignore whitespace between tags (except inside <pre> and <textarea>). Beautifying or minifying has no visual effect on rendered pages.
Are void elements handled correctly?
Yes. Self-closing elements like <br>, <img>, <input>, <meta>, and <link> are not given closing tags or extra indentation.
What about inline elements?
Inline elements like <span>, <a>, <strong>, and <em> are treated as inline and not given their own indent level to avoid breaking text flow.
Are <script> and <style> blocks preserved?
Yes. The content inside <script>, <style>, <pre>, and <textarea> blocks is kept verbatim to avoid breaking code or formatted text.
Is my HTML sent anywhere?
No. All processing is done entirely in your browser — nothing is sent to a server.
