IconVault's JS Minifier shrinks JavaScript for production: paste code and get a compact version with whitespace, comments, and line breaks removed. It also beautifies minified code back into readable form. A real string and regex aware tokenizer powers it, so it never confuses a regex literal with division or breaks a template literal.

Newlines are preserved exactly where ASI safety needs them, so minified output behaves like your original code. Paste, click, copy, done. Honest note: for huge build pipelines use a bundler like esbuild; this tool is for quick snippets and one-off files. Free and runs fully in your browser.
