Frequently Asked Questions
How much space does it save?
Typically 20-30% for small files, but strictly removes formatting. The data itself remains untouched.
Can machines read minified JSON?
Yes. Computers do not care about spaces or newlines. Minified JSON is parsed exactly the same as formatted JSON, just faster (fewer bytes to read).
Is it safe?
Yes. It only removes 'insignificant' whitespace outside of string values. Spaces *inside* your text strings ("Hello World") are preserved.
