Frequently asked questions.
Does minification change my data?
No. Whitespace is removed but every key, value, and structural character is preserved exactly.
How small can my JSON get?
Typically 60–80% smaller than the pretty-printed version, depending on key and value lengths.
Is my JSON sent anywhere?
No. Minification runs entirely in your browser.
