What does this tool do?
| Direct answer | HTML Minifier removes HTML comments and collapses whitespace between tags for smaller documents. |
| Key fact | Whitespace between block-level tags is safe to remove; browsers collapse it when rendering anyway. |
| Processing | Runs locally in your browser; no data is sent to a server. |
How to use

Example
Input
<div> <p> Hello </p> <!-- note --> </div>

Frequently asked questions
Are conditional comments removed?
Standard comments are removed; content inside <pre> and <textarea> is always preserved.
Will minification break my page?
Inline text keeps single spaces between words; only inter-tag whitespace and comments are removed.
How much smaller will my HTML get?
Typical 15–30% for hand-written HTML; heavily commented files shrink more.
