This performs conservative whitespace cleanup only.
Why this tool is conservative
Reliable JavaScript minification usually requires a parser and compiler. This browser tool only normalizes obvious formatting whitespace instead of performing transformations that might break strings, regular expressions or automatic semicolon insertion.
Best use
Use it for quick cleanup of snippets. For production bundles, use a compiler-grade minifier such as Terser or esbuild in your build process.
