Question 1

What does a JavaScript formatter do?

Accepted Answer

A JavaScript formatter restructures JS code for better readability (beautify) or smaller file size (minify). Beautifying adds proper indentation, line breaks, and spacing. Minifying removes all unnecessary whitespace, comments, and line breaks to reduce file size for production deployment.

Question 2

How do I beautify minified JavaScript?

Accepted Answer

Paste your minified JavaScript code into the input area and click the Beautify button. The formatter will add proper indentation, line breaks after semicolons and braces, and consistent spacing. You can choose between 2 spaces, 4 spaces, or tab indentation.

Question 3

How much can minification reduce JavaScript file size?

Accepted Answer

JavaScript minification typically reduces file size by 30-60% depending on the code style. Code with many comments, long variable names, and generous whitespace will see the largest reductions. The formatter shows exact size statistics after each operation.

Question 4

Is this JavaScript formatter safe to use with sensitive code?

Accepted Answer

Yes. All formatting happens entirely in your browser using client-side JavaScript. Your code is never sent to any server, making it safe for proprietary, sensitive, or confidential code. The tool works offline after the page loads.
