Frequently Asked Questions

What is JavaScript Minification?

JavaScript minification (or compression) is the process of removing all unnecessary characters from JS source code without changing its functionality. This includes removing whitespace, comments, and new line characters, which results in a smaller file size and faster download and execution times in the browser.

Is it safe to use this JS Minifier?

Yes, it is completely secure. This tool processes your JavaScript code entirely within your browser (client-side). Your code is never sent to our servers, ensuring that your data and intellectual property remain private and on your own computer.
