Minify JavaScript by removing comments, whitespace, and unnecessary characters. Reduce JS file size.

Frequently Asked Questions

What does JS minification do?

It removes comments, extra whitespace, and newlines to reduce file size while keeping your code functional.

Does it rename variables?

No — this tool does safe whitespace/comment removal only. Variable renaming (uglification) requires AST parsing.

Is my code safe?

Yes — everything runs locally in your browser. Your code is never sent to any server.

How much can I save?

Typical savings are 20-50% depending on comment density and formatting style.
