Frequently Asked Questions
What is JavaScript Minification?
JavaScript minification is the process of reducing file size by removing unnecessary spaces, comments, and renaming variables for efficiency.
Why use a Minifier?
A minifier helps speed up page load times by reducing file size, making JavaScript code execute faster and improving web performance.
Does minification change how my code works?
No, minification preserves the functionality of your JavaScript while making it smaller and more efficient.
Do you store my JavaScript code?
No, all minification happens in your browser. Your code is never uploaded or stored on our servers.
What are the available minification options?
Our minifier removes unnecessary whitespace, shortens variable names (when applicable), and applies optimizations to reduce file size.
Can I minify other programming languages?
This tool is specifically designed for JavaScript. However, separate minifiers exist for CSS, HTML, and other languages.
How is this different from a JavaScript formatter?
A formatter makes JavaScript easier to read by adding spaces and line breaks. A minifier does the opposite—it compresses code to reduce size and improve speed.
Does this tool format JavaScript as well?
No, this tool is specifically for minification. If you need formatting (pretty-printing), check out our JavaScript Beautifier tool below.
