Question 1

What is JavaScript minification?

Accepted Answer

JS minification removes whitespace, code comments, and optionally shortens variable names in JavaScript files to reduce their size, improving page load speed without altering runtime behaviour.

Question 2

What is the difference between minification and obfuscation?

Accepted Answer

Minification reduces file size for performance. Obfuscation intentionally makes code hard to reverse-engineer. Our tool only minifies — variable names may be shortened but the code is not deliberately obscured.

Question 3

How much can JS minification reduce file size?

Accepted Answer

Between 30 and 60 percent is common. Large libraries with extensive JSDoc comments and formatted source see the biggest reductions.

Question 4

Can minified JavaScript cause bugs?

Accepted Answer

Only with aggressive or buggy minifiers that incorrectly remove required semicolons or mishandle edge cases. Our tool uses well-tested, conservative minification rules that preserve correctness.

Question 5

Does Sitecheck store my JavaScript?

Accepted Answer

No. Your JavaScript is processed on our servers to produce the minified output and is not stored or logged. The result is returned to you immediately.
