Frequently Asked Questions

Code minification is the process of removing unnecessary characters from source code without changing its functionality. This includes removing whitespace, line breaks, comments, and shortening variable names. The result is smaller file sizes that load faster on websites.

Code beautification (or pretty-printing) is the reverse of minification. It takes compressed, hard-to-read code and formats it with proper indentation, line breaks, and spacing, making it easier to read and debug.

Yes! Your code is processed securely and is not stored on our servers. The processing happens during your request and the code is immediately discarded after the result is returned to you.

The reduction depends on your code. Well-commented code with lots of whitespace can see reductions of 30-60% or more. Already compact code will see smaller reductions. CSS typically sees higher compression rates than JavaScript.
