💡 How Code Minification Works

HTML

Collapses whitespace between tags, removes HTML comments, shortens boolean attributes, removes optional closing tags (optional), and trims attribute values.

CSS / JS / TS

Strips block and line comments, compresses whitespace, removes trailing semicolons, eliminates empty rules (CSS), and collapses multi-line declarations.

Python / Ruby / PHP / Java / Rust

Removes single-line and block comments, strips blank lines, trims trailing whitespace per line, and compresses indentation.
