Minified JSON uses less bandwidth when sent over the network, reducing API response sizes and improving performance.

Does it validate the JSON first?

Yes. Invalid JSON produces an error message instead of minified output.

How much smaller does the JSON get?

Typically 10-30% smaller depending on how much whitespace was in the original.
