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.
