JS Minifier

JavaScript minification removes single-line comments (//), multi-line comments (/* */), unnecessary whitespace, and redundant newlines while carefully preserving string literals and regular expressions.

Typical JavaScript minification reduces file size by 30-60%, depending on how much whitespace and comments exist in the original code. Well-commented source code sees the largest reductions.

Yes, this tool uses the same minification engine as our JavaScript Minifier page. Both provide the same functionality with identical output quality.

No. This tool only removes whitespace and comments while preserving all code logic, string literals, and regular expressions. The minified output is functionally identical to the original.
