Does it preserve , and ?

Yes. Whitespace inside these tags is meaningful, so it's left intact. Same for and bodies.

Is the output still valid HTML?

Yes for the default options - we only remove whitespace where it can't change rendering. With 'remove optional tags' on, the output is more compact but relies on HTML5's optional-element rules, so be sure your parser is HTML5-compliant.

O que é?

An HTML minifier shaves bytes off an HTML document by removing whitespace and comments that don't affect rendering. The wins are biggest on hand-authored HTML with generous indentation; framework-generated output is usually already compact. Typical savings: 15-30% on raw HTML before gzip.

Quando usar

Inlining HTML into a JSON response or an email template where every byte counts. Hand-optimising a critical-path page after a Lighthouse audit. Cleaning up exported HTML from a WYSIWYG editor that left a comment on every line.

Erros comuns

Running it on Jinja / Handlebars / Vue templates - the minifier doesn't understand template tags, so {{ stuff }} survives but the surrounding whitespace might disappear in unwanted places. Removing comments that the build pipeline actually needs (build-info pragmas, IE conditional comments). And expecting big wins on already-gzipped output - HTML minification stacks with gzip but the gzip pass does most of the heavy lifting.
