Frequently asked questions
Is the JSON minifier free?
Yes. Neatly's JSON minifier is completely free, needs no sign-up, and has no usage limits.
Is my JSON kept private?
Your JSON is processed on the fly and never stored or shared — nothing is saved on our servers.
Will minifying change how my JSON works?
No. Minification only removes what a machine ignores; the meaning and structure of your JSON stay exactly the same.
