HTML Minifier

Reduced 42 to 23 characters of HTML.

How it works

• Removed comments, keeping conditional comments.
• Collapsed whitespace between tags to a single space where it is meaningful.
• Preserved script, style, pre and textarea bodies verbatim.

• Inter-tag whitespace is collapsed, not blindly deleted, so inline spacing is usually preserved.
• Minifying the result again changes nothing.

Methodology

1. Tokenise the markup into tags, comments, raw bodies and text.
2. Remove comments unless disabled, keeping conditional comments.
3. Collapse whitespace in text and inside tags; copy raw bodies verbatim.

Usage

1. Paste or type an HTML document.
2. Choose whether to remove comments.
3. Run the minifier and copy the smaller markup.

Examples

These are examples, not current values: they use fixed inputs, while the interactive tool computes live results in your browser.

Comments and whitespace removed

{
  "text": "<div>\n  <p>Hello</p>  <!-- note -->\n</div>",
  "removeComments": true
}

Comments kept

{
  "text": "<div><!-- keep me --></div>",
  "removeComments": false
}

Script body preserved

{
  "text": "<script>  var a = 1;  </script>",
  "removeComments": true
}

Limitations

Safe minification

Minification is only useful if it is safe. This minifier treats comments, raw bodies and quoted attribute values as protected, and collapses rather than deletes inter-tag whitespace.
