How much does HTML minification reduce file size?

Typically 10–30% for HTML files with generous whitespace and comments. Files with long HTML comments or highly indented templates can see larger reductions.

Does minification affect how the page renders?

No. HTML minification removes only non-functional whitespace and comments. The rendered page is visually identical.

Are inline script and style tags minified?

Yes. Content inside and tags is minified alongside the HTML to reduce the total page size.

Should I minify HTML in development?

No. Keep unminified source files for development. Minify only in your build/deployment pipeline so you can read and edit the source easily.

Is there a size limit?

There is no hard limit. Typical HTML pages are minified without issues.
