Why minify JSON?

    
Minified JSON removes all spaces, newlines, and indentation that are only needed for human readability. For API responses, config files sent over the network, or data stored in databases, minified JSON reduces payload size — often by 20–40% — which means faster transfers and lower bandwidth costs.

    
The minified output is semantically identical to the original — all data is preserved, just compacted.
