Frequently Asked Questions
How much can minification reduce file size?
Typically 10-30% reduction depending on original formatting. Pretty-printed JSON with lots of indentation sees the most savings.
Is the minified JSON still valid?
Yes! Minification only removes whitespace. The JSON structure and data remain completely intact and valid.
Can I reverse it (beautify)?
Yes, use any JSON beautifier or formatter to add formatting back. The data is unchanged, only the whitespace is removed.
