HTML Beautifier & Formatter
Format and beautify messy HTML with proper indentation. Handles void elements, inline tags, script/style blocks, comments, and DOCTYPE declarations. Minify to strip whitespace and comments.
Frequently Asked Questions
What does an HTML beautifier do?
An HTML beautifier (also called an HTML formatter or pretty-printer) takes messy, minified, or poorly indented HTML and reformats it with consistent indentation and line breaks. This makes the code easier to read, edit, and debug without changing its meaning or rendered output.
Does beautifying HTML change how the page looks?
In most cases, no. HTML treats consecutive whitespace as a single space, so adding indentation and line breaks between tags does not change the visual rendering. The only exception is content inside <pre> tags, which this tool preserves as-is.
What are void elements?
Void elements are HTML elements that cannot have child content and do not need a closing tag. Examples include <br>, <img>, <input>, <hr>, <meta>, and <link>. This beautifier recognizes all HTML5 void elements and does not expect closing tags for them.
Is my HTML data safe?
Yes. All formatting and minification happens entirely in your browser using JavaScript. No HTML is sent to any server. Your code never leaves your machine.
