JavaScript Minifier

No. The minifier preserves all logic, variable names, and function behavior. It only removes non-essential characters like whitespace and comments.

No - variable renaming (mangling) requires full AST analysis to be safe. This minifier focuses on whitespace and comment removal, which is safer and covers the majority of size reduction for well-formatted code.

No. This tool focuses on safe minification — removing whitespace, comments, and unnecessary characters. Variable renaming (mangling) requires full AST analysis to be safe and is better handled by bundlers like webpack or esbuild.

The minifier preserves all logic, variable names, function behavior, and semicolons. It only removes non-essential characters. However, always test minified code in a staging environment before deploying to production.

Typically 20-50% depending on your code's formatting. Heavily commented code with generous whitespace benefits most. For maximum optimization, combine minification with tree-shaking, code splitting, and compression (gzip/brotli).
