Stop shipping bloated HTML

Every extra space, comment, and blank line in your HTML adds weight to your page. HTML minification strips all of that out while keeping your markup fully functional. Browsers parse minified HTML identically to formatted HTML — it just loads faster.

What HTML Minifier does

Paste your HTML and the tool removes all whitespace between tags, strips comments, and collapses redundant attributes. The output is functionally identical to the input, it just loads faster.

When you need this

If you hand-code static HTML files and deploy without a build tool, this is your minifier. Also useful for email templates, where bloated HTML causes rendering issues in Outlook.

Privacy first

Your HTML never leaves your browser. No file uploads, no servers, no logs. Paste, minify, copy — done.

Frequently Asked Questions

Will minified HTML break my page?

No. Minification only removes whitespace and comments that browsers already ignore. Your page renders identically.

Does it remove inline CSS or JavaScript?

No — this tool only minifies the HTML structure. Use dedicated CSS and JS minifiers for those.

Is my HTML sent to a server?

Never. All processing happens in your browser using JavaScript. Nothing is transmitted.

How much size reduction can I expect?

Typically 10 to 30 percent for well-formatted HTML. Heavily commented code can see 40 percent or more.

Does it work with HTML5 and modern tags?

Yes — it handles all standard HTML including HTML5 semantic elements, data attributes, and inline SVG.
