Why minify HTML?
Smaller HTML documents can reduce the amount of source data transferred to visitors. Minification can complement browser caching and server-side compression such as Gzip or Brotli.
Does the tool preserve scripts and styles?
The minifier preserves the contents of script, style, pre, and textarea elements instead of collapsing their internal whitespace. This helps protect JavaScript, CSS, and preformatted content.
Is minified HTML safe to publish?
Always test generated HTML before replacing a production file. Complex documents, embedded template languages, unusual markup, and inline scripts may need a dedicated HTML parser or build tool.
