FAQ
Does this tool rename variables?
No. This tool performs basic minification (comment and whitespace removal) without variable renaming or dead code elimination. For production builds, consider tools like Terser or UglifyJS.
Is my code safe?
Yes. All processing happens entirely in your browser. Your code never leaves your device.
