How to use HTML Minifier

1. Paste your HTML. Paste or type your HTML source code into the input textarea.
2. Click Minify. Hit the Minify button to strip comments, collapse whitespace, and trim your HTML.
3. Copy the result. Copy the minified output or compare the before/after file sizes.

Is my HTML sent to a server?

No. All minification runs entirely in your browser — nothing is uploaded.

Will minification break my HTML?

The minifier only removes comments and excess whitespace. It does not alter tags, attributes, or structure, so your HTML remains valid.

How much can I expect to save?

Typical savings are 10–30% depending on how much whitespace and comments your source contains.

Does it remove conditional comments?

Yes, all HTML comments including conditional IE comments are removed. If you need those, remove them from the output manually.

Can I minify partial HTML snippets?

Absolutely. The tool works on any HTML fragment — it doesn't require a full document.
