FAQ

Will minified code still work correctly?

Yes, minification only removes whitespace, comments, and redundant syntax without changing functional logic, fully compatible with the original code.

How much space can I save?

Typically 30%-70% reduction depending on the proportion of comments and whitespace in your source code.

What is the difference between minification and obfuscation?

Minification removes redundant characters to reduce size. Obfuscation renames variables to make code hard to read. This tool performs minification.
