Minify HTML for a Lighter Page

The HTML Minifier shrinks your markup by stripping comments and collapsing insignificant whitespace, while safely preserving the contents of <pre>, <textarea>, <script>, and <style> tags. Smaller HTML means faster first paint and a lighter total page weight.

Beautify Messy or Minified Markup

Switch to Beautify mode to reformat compressed or inconsistent HTML into clean, properly indented code. It's ideal for inspecting a minified page or tidying up generated markup.

Safe, Private, and Instant

Everything runs locally in your browser — your HTML is never uploaded. Results appear instantly as you type, with no file-size limits and no sign-up.

Frequently Asked Questions

Is it safe to minify HTML?

Yes. This minifier preserves the exact contents of <pre>, <textarea>, <script>, and <style> tags so nothing that depends on whitespace or formatting breaks. It only collapses insignificant whitespace and removes comments.

Does it remove HTML comments?

It removes normal comments to save bytes, but intentionally keeps Internet Explorer conditional comments (<!--[if ...]-->) since those are functional.

Why minify HTML?

Smaller HTML documents download and render faster. Combined with minified CSS and JavaScript, it reduces total page weight and improves load times and SEO.

Can I re-indent minified HTML?

Yes. Switch to Beautify mode to reformat compressed or messy markup into clean, properly indented HTML that is easy to read and edit.

Is my HTML kept private?

Yes. Processing happens entirely in your browser — your markup is never uploaded or stored anywhere.
