HTML Minifier details

First, enter HTML in HTML Minifier. Next, review Minified HTML, Original size (chars), Minified size (chars), and Saved. Additionally, HTML Minifier uses 3 input fields and 4 output blocks so the result is easy to scan and copy.

Paste any HTML markup and get a tightly-packed, production-ready version. Whitespace between tags is collapsed, comments and DOCTYPE are normalised, and you can optionally minify embedded <script> and <style> blocks. Content inside <pre>, <textarea>, and <code> is preserved verbatim. Conservative; never rewrites identifiers in scripts. Runs entirely in your browser; your markup never leaves this page.
