Frequently Asked Questions

Does HTML minification affect SEO?

No. Search engines parse minified HTML the same as formatted HTML. Minification can actually improve SEO by reducing load times.

Will minification break my JavaScript?

Inline scripts are preserved. However, for complex pages, test thoroughly after minification.

Should I minify HTML with dynamic content?

For server-rendered pages, enable minification in your templating engine or server configuration instead.

What about accessibility?

HTML minification does not affect accessibility. All ARIA attributes and semantic elements are preserved.
