How to Use This Tool

Paste your HTML, optionally keep comments, then minify. Copy the compact version into your build.

This is a simple whitespace/comment minifier — always test pages that rely on formatting, such as <pre> blocks.
For production, pair this with Gzip/Brotli compression on your server.

Is minified HTML safe?

Yes for whitespace removal. Removing conditional comments or whitespace-sensitive content (like <pre>) could change rendering — always test.

Why is <pre> content kept?

Preformatted text and textarea content display whitespace literally, so collapsing it would change the visible output.

How does minification help performance?

Smaller files download and parse faster. Combined with compression, savings are typically 30-50% on HTML.

Is my HTML uploaded?

No — minification runs entirely in your browser.

Minify this snippet (49 bytes):

<!-- note -->
<div>
  <p>Hello   World</p>
</div>

The output (29 bytes) drops the comment and collapses whitespace:

<div><p>Hello World</p></div>

Saved bytes — the difference between the original and minified sizes; smaller HTML downloads and parses faster.
Savings percent — the proportion of the file removed, typically 30-50% on hand-formatted HTML.
Removed comments —  blocks are deleted when the option is on, shrinking the file without affecting content.
