Frequently Asked Questions
Is this safe for production code?
This tool provides basic minification. For production, use tools like Terser or UglifyJS which handle edge cases better. This is great for quick optimizations.
Does it rename variables?
No, this tool doesn't rename variables. It only removes whitespace and comments. Use professional tools for full obfuscation.
Will minified code break?
Basic minification is safe, but always test your code after minification. Some edge cases with regex or template literals may need special handling.
Can I beautify minified code?
Yes! The beautify mode will restore formatting and readability to minified JavaScript code.
How much size reduction?
Typically 30-60% for files with lots of comments and whitespace. Code that's already compact sees less reduction.
