Minify JavaScript Online
Remove comments, extra whitespace, and unnecessary characters from JavaScript code to reduce file size. The minifier handles single-line comments (//), multi-line comments (/* */), and collapses whitespace while preserving string contents.
When to Minify
Minified JavaScript loads faster and reduces bandwidth. While build tools handle this automatically in most projects, this tool is useful for quick one-off minification or checking output size.
