Free HTML Minifier

Shrink your HTML for faster page loads. This free minifier strips comments and collapses whitespace between tags — while carefully preserving pre, script, style, and textarea content — then reports exactly how many bytes you saved.

Minified HTML

Private by design. This tool runs 100% in your browser — your code is never uploaded to any server.

How to Use the HTML Minifier

  1. Paste your HTML into the input box.
  2. Choose whether to remove comments and collapse whitespace.
  3. Click Minify HTML to compress it instantly.
  4. Check the savings report, then copy or download the result.

Features

The minifier removes HTML comments (optionally keeping conditional comments), collapses whitespace between tags to nothing, trims redundant spaces inside tags, and strips empty lines — all while passing pre, script, style, and textarea blocks through untouched so embedded code keeps working. Before/after byte counts with percentage saved make the benefit concrete.

Benefits & Use Cases

Smaller HTML means faster time-to-first-byte and quicker parsing, especially on mobile connections. Developers minify landing pages and email templates before deploy, and anyone hand-optimizing a static site gets measurable wins without a build pipeline. Local processing keeps proprietary markup private.

Tips

Keep a readable source file and treat minification as a deploy step — never edit minified HTML directly. If your layout uses inline-block spacing tricks, test after minifying, since removed whitespace can tighten gaps.

Frequently Asked Questions

What does HTML minification remove?

Comments, line breaks, indentation, and redundant spaces between tags. The document structure, attributes, and content stay identical — only the invisible formatting is stripped.

Will it break my JavaScript or CSS?

No. Script, style, pre, and textarea contents are excluded from whitespace collapsing, so embedded code and preformatted text work exactly as before.

How much smaller will my HTML get?

Typically 10–25% for hand-written HTML and more for heavily commented templates. The tool shows your exact byte savings.

Should comments always be removed?

Almost always for production. The exception is conditional comments targeting old IE versions — enable the “keep conditional comments” option if you still support them.

Is my HTML uploaded anywhere?

No. Minification runs entirely in your browser — your markup never leaves your device.
