FAQ
What is minification?
Minification is the process of removing unnecessary characters from code (such as whitespace, comments, and newlines) without changing its functionality. This reduces file size and can improve website loading speed.
Is this a full JavaScript uglifier?
No. This tool performs basic minification by removing comments, extra whitespace, and collapsing lines. For production use requiring variable renaming and advanced optimizations, consider tools like Terser or UglifyJS.
Will minification break my code?
This tool applies safe transformations that should not break well-formed code. However, always test your minified code before deploying to production. Keep a copy of your original source code.
How much file size can I save?
Savings depend on your original code formatting. Heavily commented and well-indented code may see 30-60% size reductions. Already compact code will see smaller improvements.
