Frequently Asked Questions

Does minification change what my JavaScript does?

No. It only removes comments, whitespace and shortens variable names where safe. Functionality is preserved.

What is the difference between minification and obfuscation?

Minification compresses code. Obfuscation makes it intentionally hard to read. This tool does minification only.
