Frequently Asked Questions
Why should I minify JSON?▼
Minifying JSON removes unnecessary whitespace, reducing file size by 20-60%. This improves load times when transmitting JSON over networks and reduces storage requirements.
Does minification affect data integrity?▼
No. Minification only removes whitespace (spaces, tabs, newlines) that are not part of string values. The actual data is preserved exactly as-is.
