How to Beautify or Minify HTML
The HTML Beautifier formats messy HTML into clean, indented markup — or minifies it for production by stripping whitespace and comments.
- Paste your HTML into the editor.
- Click Beautify to add proper indentation, or Minify to strip all whitespace.
- Copy the result or download it as a .html file.
Why Format HTML?
Well-formatted HTML is easier to read, debug, and maintain. Consistent indentation reveals the nesting structure of elements at a glance. Minified HTML, on the other hand, reduces file size for production — removing whitespace, comments, and optional tags can shave 10–30% off payload size, improving page load time.
Why Use Our HTML Beautifier?
- Customizable indentation — choose 2 spaces, 4 spaces, or tabs.
- Minify mode — strip whitespace and comments for production builds.
- Preserves inline elements — <span> and <a> tags stay on one line where appropriate.
- Client-side processing — your HTML never leaves your browser.
Frequently Asked Questions
Does minifying HTML break anything?
Minification removes unnecessary whitespace and comments. It does not change the DOM structure or affect rendering. Inline JavaScript or CSS within the HTML is preserved.
Can I beautify HTML with embedded CSS and JavaScript?
Yes. The tool formats HTML structure and can optionally format embedded <style> and <script> blocks as well.
Does it fix broken HTML?
The beautifier formats existing markup but does not repair invalid HTML (missing closing tags, etc.). Use an HTML validator for that.
Is my HTML private?
Yes. Processing is entirely local — no data is sent to any server.
