Strip whitespace, remove comments, and shrink your HTML in real-time. Entirely browser-side — your code never leaves your device.
Built for developers who care about performance, SEO, and Core Web Vitals.
Automatically strips all HTML comments from your code, eliminating debug notes and developer annotations from production output.
Collapses multiple consecutive spaces, tabs, and newlines into single spaces, reducing file size while preserving proper text rendering.
Optionally compress embedded <style> and <script> blocks within HTML for maximum possible file size reduction in a single pass.
No data ever leaves your browser. Perfect for sensitive HTML templates, internal tools, and proprietary code that can't be shared externally.
Live display of original size, compressed size, bytes saved, and percentage reduction. Tracks tag count, attribute count, and DOM depth.
Download the minified HTML as a .html file immediately. One click copy to clipboard also available for fast integration into your workflow.
Simple, fast, and completely free — no registration required.
Copy HTML from your editor, browser source, or CMS template and paste into the input area.
Toggle which elements to remove: comments, whitespace, optional tags, inline CSS/JS.
Instant compression with live stats showing exactly how much size was saved.
Copy minified HTML to clipboard or download as a .html file ready for deployment.
Every web page is ultimately delivered to browsers as HTML. The size of that HTML directly affects how quickly pages load, and page speed is a confirmed Google ranking factor. HTML compression, also called HTML minification, is the process of removing all non-essential characters from HTML source code — whitespace, line breaks, comments, and redundant attributes — to produce the smallest possible file without changing how the browser renders the page.
A typical hand-coded or CMS-generated HTML document contains significant amounts of formatting whitespace added for developer readability. Each space, tab, and newline character adds bytes to every HTTP response. For a busy website serving millions of pages per month, even small per-page savings translate to substantial bandwidth reductions. More importantly, smaller HTML files result in faster Time-to-First-Byte (TTFB) and quicker page parsing, both of which positively influence Core Web Vitals scores and search engine rankings.
Using this HTML compressor is effortless. Paste your HTML into the input area, choose your compression settings (remove comments, collapse whitespace, minify inline CSS and JS), then click Compress. The tool processes entirely in your browser — no server upload, no privacy risk. The output panel shows your minified HTML alongside precise statistics: original size, compressed size, bytes saved, and percentage reduction.
Always test minified HTML in a staging environment before deploying to production. Keep a formatted source file in version control and use minification as a build step rather than editing minified files directly. Be cautious with optional-tag removal if your HTML relies on specific browser parsing behaviour. For maximum performance gains, combine HTML minification with GZIP or Brotli encoding on your web server. Together, these techniques can reduce HTML delivery size by over 80%, significantly improving Lighthouse scores and user experience for visitors on mobile networks.
