Frequently Asked Questions
📦 What is JSON Minify?
JSON Minify removes all unnecessary whitespace, tabs, and newlines from JSON data, reducing file size while keeping the data structure intact.
🔒 Is my data private?
Yes! 100% client-side. Your JSON never leaves your browser. No server uploads, no data storage.
⚡ How much can I save?
Typically 30-80% size reduction. Pretty-printed JSON with lots of whitespace sees the biggest gains.
🔄 Can I revert minification?
Use the "Pretty Print" button to format minified JSON back to a readable structure.
📋 What's the maximum size?
No hard limit! The tool handles JSON of any size, limited only by your browser's memory.
🎯 Is it valid JSON?
Yes! The tool validates your JSON before minifying. Invalid JSON shows an error.
