About HTML Formatting
HTML (HyperText Markup Language) is the standard markup language for creating web pages. Properly indented HTML is significantly easier to read and debug, especially when dealing with deeply nested structures like forms, tables, and layout components. This tool instantly prettifies or minifies your HTML.
Formatting vs Minification
Formatting adds whitespace and line breaks to make the structure visible at a glance. Minification does the opposite: it strips all unnecessary whitespace and comments to reduce file size for production. Both operations preserve the rendered output of the page. Use formatting during development for readability and minification before deployment for performance.
Void Elements
HTML defines certain elements as "void" elements that cannot have children and do not require a closing tag. Examples include <br>, <hr>, <img>, <input>, <meta>, and <link>. This formatter recognizes all standard void elements and handles them correctly without expecting a matching closing tag.
