Why Minify Your Code?
Performance
Removing unnecessary whitespace, line breaks, and comments drastically reduces file size. This speeds up download times and improves your Core Web Vitals.
100% Privacy
We utilize a background Web Worker to process your code entirely inside your browser. Your proprietary source code never touches our servers.
AST Engine
We use industry-standard Abstract Syntax Tree (AST) parsers (Terser and CSSO) to ensure your code logic remains perfectly intact without destructive regex replacements.
Frequently Asked Questions
Is it safe to minify my production code here?
Yes. This tool is 100% client-side. Your code is processed locally in your browser and is never transmitted anywhere.
Will minifying break my JavaScript?
No. Standard regex strippers can accidentally break strings or logic. We use Terser (the exact same engine powering Webpack and Vite) which guarantees perfect logical preservation.
How do I preserve license comments?
Click the gear icon in the toolbar and select "Preserve Comments" before minifying. This keeps /*! ... */ blocks intact.
