Minify HTML to reduce file size, or beautify minified HTML back into readable, indented code.
Yes, HTML comments (<!-- like this -->) are removed during minification, along with unnecessary whitespace between tags.
No, standard HTML minification only removes whitespace and comments — it doesn't alter tags, attributes, or content in ways that change rendering.
Whitespace inside these tags is meaningful and preserved by browsers, so exercise care when minifying HTML containing such elements.
This tool compresses HTML code by removing comments and unnecessary whitespace between tags to reduce file size, or reformats minified HTML back into readable, properly indented code.
Minifying HTML removes comments, extra whitespace, and line breaks between tags that exist purely for source readability but add nothing to how the page renders. Smaller HTML files transfer faster over the network, which contributes to faster initial page load — particularly noticeable for larger pages or users on slower connections. Most production web deployment pipelines minify HTML alongside CSS and JavaScript as a standard optimization step.
<!-- and -->.A small number of HTML elements — most notably <pre> and <textarea> — preserve whitespace exactly as written, since it's meaningful to their content (like code formatting or default text). This tool performs general-purpose minification aimed at typical markup; if your HTML contains these whitespace-sensitive elements with meaningful internal formatting, review the minified output carefully before using it.
All processing happens directly in your browser — your HTML code is never sent to a server.
