Question 1

What does JavaScript minification do?

Accepted Answer

JS minification removes whitespace, comments, and unnecessary characters from JavaScript code. This reduces file size and improves page load speed.

Question 2

Is my JavaScript code sent to a server?

Accepted Answer

No. All minification happens in your browser. Your code never leaves your device.

Question 3

What is the maximum JS file size?

Accepted Answer

Up to 200KB of JavaScript text.

Question 4

Will minification break my JavaScript?

Accepted Answer

Basic whitespace removal is safe. The tool removes comments and extra whitespace without renaming variables, so your code remains functional.

Question 5

What is the difference between minification and obfuscation?

Accepted Answer

Minification removes whitespace to reduce size. Obfuscation renames variables to make code harder to read. This tool does minification only.
