Question 1

What does HTML minification remove?

Accepted Answer

Comments (), whitespace between tags, optional closing tags (, in some contexts), optional quotes around attribute values, and sometimes default attribute values. Aggressive minifiers also inline CSS/JS. This tool performs safe whitespace and comment removal.

Question 2

Can HTML minification break layouts?

Accepted Answer

Possibly. Collapsing whitespace between inline elements can affect rendering — removing the space between two <span> elements removes the visual gap between them. Safe minification modes preserve inter-element whitespace. Test the minified output before deploying.

Question 3

Is HTML minification worth doing?

Accepted Answer

For most modern sites, server-side gzip/brotli compression provides 70–90% size reduction, making HTML minification secondary. It has more impact on large HTML documents (generated pages) and when every byte of bandwidth matters.
