ℹ️ About this tool
This JS / CSS Minifier processes your code entirely in your browser using pure JavaScript — no code is ever uploaded to any server. For JavaScript it removes single-line comments (//), block comments (/* … */), collapses whitespace and removes unnecessary spaces around common operators. For CSS it strips comments, collapses whitespace and removes unnecessary spaces around : { } ; , characters. The savings percentage is shown so you can gauge the impact. Note: for production builds a dedicated tool (Terser, esbuild, etc.) will produce better results — this tool is great for quick, private minification.
