FAQ

What does minifying JSON actually remove?

All whitespace, line breaks and indentation between tokens — the data itself is untouched, only formatting is stripped.

Will minifying change the values in my JSON?

No — minifying only removes whitespace; keys, values and structure stay exactly the same.

Does this tool send my JSON to a server?

No — it runs entirely in your browser via JSON.parse/JSON.stringify, nothing is uploaded.
