JavaScript Minifier

Minify JavaScript by removing whitespace, comments, and shortening variable names

All processing happens in your browser. No data is sent to any server.
Minified Output

Basic minification only (comment removal, whitespace collapse). For production use, consider terser or esbuild.

Why This Tool

Minified JavaScript loads faster and reduces bandwidth costs. This tool strips whitespace, removes comments, and compresses your JavaScript code — useful for quick one-off minification without a build tool.

How It Works

Paste your JavaScript code into the editor. The minifier processes it and outputs the compressed version with size comparison stats. Copy or download the minified result.
