About the HTML Minifier

This HTML Minifier shrinks markup by stripping comments and unnecessary whitespace so pages and email templates transfer fewer bytes. Smaller HTML can load a bit faster on slow connections and keeps shipped templates lean when you do not need human-readable indentation in production.

Paste formatted HTML, minify it, then deploy the compact version. Always keep a readable source file in your repo — minify as a build or publish step, not as your only copy.

Good use cases

  • Reducing HTML email template size before ESP upload
  • Shipping static snippets or widget markup with less overhead
  • Comparing before/after size when optimizing a landing page shell

How to use

  1. Paste the HTML you want to compress.
  2. Run the minifier and check that critical content still looks correct.
  3. Copy the minified output into your production asset or CMS field.

Cautions

  • Some templates depend on whitespace inside inline elements — spot-check the rendered page.
  • Do not minify away conditional comments or build markers you still need.
  • Keep a formatted source; regenerating from minified HTML is painful.

FAQ

Does minifying HTML replace gzip? No. Minify reduces source size; compression still helps on the wire.

Should I minify HTML inside a CMS WYSIWYG? Usually no — editors expect readable markup. Minify at the edge or build step when possible.
