Frequently Asked Questions
FAQs about JavaScript Minifier
Does this minifier remove all comments?
Yes. Both single-line comments (//) and multi-line block comments (/* ... */) are removed from the output.
Will the minified code still run correctly?
Yes. The minifier only removes whitespace and comments, it does not alter logic, variable names, or expressions.
Does it handle template literals?
The minifier uses regex-based processing. Template literals with backticks are preserved, though embedded newlines inside them may be collapsed.
Is this safe for production use?
This is a basic regex-based minifier suitable for simple scripts. For complex projects, use a dedicated bundler like esbuild, Terser, or webpack.
Is my code safe?
All processing runs entirely in your browser. No code is ever sent to a server.
