What is HTML Minifier?
Remove HTML whitespace and comments (IE conditional comments are kept) to potentially reduce page size. Content inside <pre>, <textarea>, <script>, and <style> tags is left untouched; this tool does not minify the CSS or JavaScript inside those blocks. Shows before/after byte counts and percentage reduction.

Frequently asked questions
Common questions about HTML Minifier.
The tool preserves content inside pre, textarea, script, and style tags exactly as written, since collapsing whitespace there can change rendering or break code. Everything else has whitespace and comments stripped safely.
The reduction varies by document. Pages with heavy inline comments and formatting whitespace may see the biggest savings, while some inputs change very little.
It may reduce bytes transferred, especially when a document contains many comments or formatting spaces. Combine it with gzip or Brotli compression and test the result in your deployment.
No — script and style block contents are intentionally left untouched by this tool. Pair it with the dedicated CSS or JS minifier for those.
