Question 1

What does minifying JSON do?

Accepted Answer

Minification removes all unnecessary whitespace (spaces, tabs, newlines) from JSON without changing the data. This reduces file size, which speeds up data transfer over networks.

Question 2

When should I minify JSON?

Accepted Answer

Minify JSON for production API responses, config files shipped with apps, or any JSON sent over a network. For files you'll edit manually, keep the formatted version.

Question 3

How much smaller does JSON get?

Accepted Answer

Typically 15–40% smaller, depending on how much whitespace the original had. Minification has no effect on JSON that is already compact.
