HTML Formatter & Minifier
Format HTML to make it readable, or minify it to reduce file size.
About this tool
The HTML Formatter takes compressed or poorly indented HTML and outputs it with proper nesting, indentation, and line breaks, making the document structure visually clear. The Minifier removes all non-essential whitespace and comments to reduce file size for production use.
HTML indentation directly reflects document structure — properly nested markup is faster to scan, easier to debug, and less likely to contain structural errors like unclosed tags. When copying HTML from browsers' DevTools, email templates, or CMS exports, the formatter turns it into clean, readable source in seconds.
HTML minification is particularly valuable for static pages and server-rendered applications where every kilobyte of HTML payload affects Time to First Byte and Largest Contentful Paint. Inline comments and formatting whitespace that helps developers are unnecessary overhead for browsers, and stripping them has zero impact on rendering.
