About this tool

The HTML Minifier runs the well-known html-minifier library in your browser to strip comments, whitespace and redundant attributes, with optional inline CSS/JS minification and removal of optional tags. The result shows input and output sizes with the percentage saved. Since the processing is local, you can minify templates containing secrets or customer data.

Reverse it with HTML Unminify.

Frequently asked questions

Will minification break my page?

The default options are safe. "Remove optional tags" and "remove attribute quotes" are valid HTML5 but can confuse old tools; test before deploying.

How much does it save?

Typically 10–30% on hand-written templates, less on already compact markup; gzip on the server adds much more.

Are my files or data uploaded?

No. The tool is plain JavaScript that runs in your browser; the files or data you provide here are never uploaded to our servers.
