HTML minifier
Minify and improve the performance of HTML code.
In short
Minify HTML markup by removing whitespace and comments while preserving the rendered output.
What Is HTML Minification?
HTML minification removes characters from HTML that browsers do not need to render the page — whitespace between tags, HTML comments, and optional line breaks.
The result is a smaller HTML document that transfers faster, with no change to how the page looks or behaves in a browser.
Effect on Page Performance
HTML is transferred on every page load. Reducing its size contributes to faster Time to First Byte and smaller overall page weight.
While HTML minification typically produces smaller savings than CSS or JavaScript minification, it is still recommended as a low-effort optimisation for production sites.
Best For
- Developers optimising page weight for speed
- Site owners reducing page size for Core Web Vitals
- Developers checking minified output of HTML templates
Limitations of this tool
- Very large HTML documents may be truncated before processing.
- Whitespace-sensitive content (such as text inside <pre> tags) is preserved.
Frequently asked questions
- Does HTML minification break the page?
- No. Minification removes only insignificant whitespace and comments. The structure, tags, and attributes of the HTML are preserved.
- Does it remove whitespace inside text content?
- No. Whitespace inside visible text is preserved. Only whitespace between HTML tags is removed.
- Should I minify HTML in production?
- Yes, as part of a broader performance optimisation strategy. Most hosting platforms and CDNs can be configured to serve minified HTML automatically.
