Minify JavaScript Online
A JavaScript minifier helps reduce script size by removing whitespace, comments and formatting. Smaller scripts can reduce transfer size and are useful for production snippets, simple websites and quick optimization tasks.
This browser-based tool provides lightweight minification. It is not a full compiler like advanced build tools, so important production code should be tested after minification. For complex projects, use bundlers and professional minifiers as part of your build process.
