What is the difference between minifying and beautifying HTML?

Minifying reduces bytes for delivery, while beautifying improves readability for humans during development and review.

Can I use this before editing templates?

Yes. Formatting first helps you spot nesting issues and class placement before making template changes.

Will beautifying change what the HTML means?

No. It only changes whitespace and indentation for readability; it does not intentionally rewrite tags, attributes, or content.
