Why minify HTML

Smaller payloads mean faster first paint for static snippets and fewer bytes over the wire. Doing it locally keeps proprietary templates off third-party minifier sites.

How it works

  1. Paste HTML (fragment or document).
  2. Click Minify HTML or keep Live on.
  3. Check the stats bar for percent saved and character counts.
  4. Copy HTML or chain CSS / JS minifiers.

FAQ

  • pre / code / textarea? Whitespace inside text nodes is still collapsed to single spaces—avoid minifying blocks where meaningful spaces matter, or use a build tool.
  • Inline scripts? Content is not executed; only comments and whitespace rules apply. Review output before deploy.
  • Huge pages? Prefer samples in-browser; turn off Live for megabyte pastes.
