Frequently Asked Questions

Can I minify multiple file types at once?

You can minify HTML with embedded CSS and JavaScript together, or each separately.

Is minified code reversible?

Formatting can be restored with beautifiers, but comments and original variable names are lost.

How much total size reduction from minifying HTML, CSS, and JS?

Expect 20-50% combined reduction depending on coding style and comment density across all three file types. Individual results vary by file composition.

Should I minify during development?

No, keep code readable during development. Minify only for production deployment.
