Frequently Asked Questions

Why minify JSON?

Minified JSON removes all unnecessary whitespace, reducing file size by 20-40%. This speeds up API responses and reduces bandwidth usage in production.

Does minifying change the data?

No. Minifying only removes whitespace (spaces, tabs, newlines). The data structure and values remain identical.
