What Is Code Unminification?

Unminifying (or beautifying) code restores spacing, indentation, and line breaks that were removed during the minification process. While minification reduces file size for production environments, developers often need formatted code for analysis, debugging, or learning purposes.

This tool focuses purely on formatting without altering your logic.
