Everything you need to know about minifying HTML

What does minifying do?

Strips unnecessary whitespace and comments from HTML, reducing the size of the initial document a browser downloads — a smaller effect than minifying JS/CSS typically, but still a small, real improvement for page load.

When you actually need this

  • Shipping a static HTML page without a build tool already minifying it.
  • Reducing bandwidth for a high-traffic static page.

Frequently Asked Questions

Does this change how the page looks when rendered?

No — browsers already collapse most whitespace between tags when rendering, so removing it from the source doesn't change the visible layout; only comments and extra whitespace in the source file are removed.

Will this remove whitespace I actually need, like inside a <pre> block?

Whitespace is collapsed primarily between tags; if your markup depends on specific whitespace being preserved inside content (like in <pre> or textarea), check the output carefully before using it.

Why minify HTML at all?

Smaller file size means slightly faster page loads, especially noticeable on templates with lots of comments or heavily indented markup.

Does this tool send my HTML to a server?

Yes — it's sent to our servers to minify and the result is returned to you; nothing is stored.

Is this tool free to use?

Yes — completely free, with no signup and no usage limits for casual use.
