About JavaScript Minifier

Readable JavaScript contains comments and formatting that are useful during development but add bytes when source is embedded or transferred. This lightweight minifier removes comments and collapses unnecessary whitespace while preserving quoted strings and template content covered by its parser contract. It is designed for quick snippets and inspection workflows; production applications should still use a full build tool with syntax-aware optimization.

Runs locally in your browser. The text you enter is not uploaded to CodeStorms.

→ Compact a small JavaScript snippet before embedding it in a page. → Compare readable and compact output while debugging a build pipeline. → Reduce whitespace in a standalone script used in documentation.
