Private by design. Your code and data are processed in your browser. Nothing is uploaded, logged or stored, so it is safe for API responses, configs and other internal data.

About this tool

What does HTML minification remove?

Minification removes characters browsers do not need: comments, indentation, line breaks and repeated spaces. Whitespace around block elements such as div, p and li is removed completely, while spaces between inline text are collapsed to one so words do not run together.

Content inside pre and textarea tags is protected because spacing matters there. Conditional comments for old Internet Explorer are kept. The "remove all space between tags" option squeezes out a little more, but can remove meaningful spaces between inline elements, so check the result if you use it.

Minification tips

Keep the original

Always edit the readable version and minify a copy.

Enable compression too

Server compression such as gzip or Brotli saves even more on top of minifying.

Test after minifying

Open the page and click around to confirm nothing changed.

Automate for big sites

Build tools can minify automatically every time you publish.

FAQ

HTML Minifier FAQs

Is HTML minification safe?

Yes, with the default options. The aggressive option can remove spaces between inline elements, so test the page if you use it.

Does it minify inline scripts?

Yes, when the option is on. Scripts of non-JavaScript types, such as JSON-LD, are left unchanged.

How much smaller will my HTML be?

Typically 10% to 30%, depending on comments and indentation.

Is my code uploaded?

No. Minification runs in your browser.
