What is JavaScript Minifier?

This JavaScript minifier reduces code size by removing single-line and multi-line comments (preserving URLs), collapsing whitespace, and optionally removing console.* calls and debugger statements.

Shows before/after character counts with percentage reduction. Note: for production minification with variable mangling, use tools like Terser or esbuild.

FAQ

Is this as good as Terser/UglifyJS?
This tool handles basic minification (comments, whitespace, console removal). For production use with variable mangling and tree-shaking, dedicated tools like Terser are recommended.
Does it preserve URLs in comments?
Yes — single-line comments containing '://' are preserved since they're likely URLs, not code comments.
