JavaScript Minifier
Compress JavaScript snippets into smaller output.
Review minified output before using it
This lightweight utility removes whitespace and comments using text rules. It does not parse the full language grammar. Strings, regular expressions, template literals and whitespace-sensitive expressions may change meaning. For production builds, use your project’s parser-based build tool and run its normal checks.
