HTML Compressor

Free HTML Compressor — Minify HTML for Faster Loading

Every byte of HTML the browser downloads adds to page load time. Unoptimized HTML templates often contain extensive whitespace, developer comments, redundant attributes, and unnecessary formatting. This free HTML Compressor strips all of that out, producing lean, compact markup that loads faster without changing how the page renders or functions.

Paste your HTML and click Compress. The tool removes whitespace between tags, strips HTML comments, and removes optional closing tags and redundant attributes. The output is functionally identical to the input but significantly smaller.

HTML minification is most impactful on large template-heavy pages. A typical HTML page can be reduced 10–30% in size by minification alone, and dramatically more when combined with Gzip or Brotli compression at the server level.

What HTML Compression Removes

Whitespace between tags. The spaces and line breaks between <div>, <p>, and other tags that make HTML readable but add no rendering value.

HTML comments. Developer comments (<!-- comment -->) are stripped. They are invisible in the browser but add bytes to every page load.

Redundant attributes. Optional attributes with default values (like type="text" on input fields, type="text/javascript" on script tags) can be removed safely.

Optional closing tags. Certain HTML elements do not require closing tags in HTML5. Minifiers may remove them to save a few more bytes.
