HTML-Verkleinerer
Compress HTML code by removing comments, whitespace and simplifying attributes.
About HTML Minification
HTML minification reduces file size by removing comments, collapsing whitespace between tags, removing unnecessary attribute quotes, and simplifying boolean attributes (e.g., disabled="disabled" becomes disabled). Smaller HTML files load faster and improve page speed scores. All processing happens in your browser.
How It Works
- Paste HTML: Enter any HTML document or fragment — templates, component markup, or full pages.
- Select options: Choose what to remove: comments, whitespace between tags, optional end tags, and boolean attribute values.
- Minify: Click to produce the smallest valid HTML that renders identically to the original.
- Copy output: The minified markup is ready to deploy or embed in your build pipeline.
Why Minify HTML?
HTML minification reduces the initial document transfer size — the first thing a browser downloads on every page load. While HTML is typically compressed with gzip or Brotli at the server level, removing unnecessary characters before compression makes the compression even more effective. This is especially impactful for server-side rendered pages and static sites where every kilobyte counts toward Time to First Byte (TTFB) and Largest Contentful Paint (LCP) — two Core Web Vitals that directly influence search rankings.
What Gets Removed
- HTML comments —
<!-- ... -->blocks - Inter-element whitespace — spaces and newlines between tags
- Optional end tags —
</li>,</td>where valid - Attribute quotes — around simple values
- Boolean attributes —
disabled="disabled"→disabled
