Frequently Asked Questions
What is the difference between JSON minify and JSON format?
Formatting adds whitespace for readability, while minifying removes unnecessary whitespace to reduce size. Both represent the same data when valid.
Will minifying JSON change data types or values?
No. Minification only removes spaces, tabs and line breaks outside string values. Keys, values and data types remain unchanged.
Is my JSON uploaded to a server?
No. This tool runs 100% client-side in your browser. Your JSON is never transmitted to any backend.
