About the HTML Minifier

Collapse the whitespace between HTML tags to reduce file size and speed up page loads. Paste markup, upload a file, or fetch a page by URL, and get compact HTML instantly. Everything runs in your browser — nothing is uploaded.

Common use cases

Faster pages: ship smaller HTML to reduce transfer time.
Email templates: trim bulky markup before sending.
Build steps: minify partials without a full toolchain.

How it works

Paste HTML, upload a file, or fetch it from a URL.
Click Minify.
Copy the result or save it, and check the size reduction.

Frequently asked questions

Will it break my page?

This is a whitespace collapse, not a full parser. Content inside <pre>, <textarea>, or <script> where spacing matters should be reviewed before use.

Is my data uploaded?

No. Minification happens locally in your browser — your data never leaves your device.
