JSON Minify
Minify JSON data
Frequently Asked Questions
What does JSON minification do?
Minification removes all unnecessary whitespace, line breaks, and indentation from JSON. {"name": "Alice", "age": 30} becomes {"name":"Alice","age":30}. The data is identical; only formatting is removed to reduce size.
How much space does JSON minification save?
Typically 20-40% reduction depending on the original formatting. A 100KB formatted JSON file might minify to 60-80KB. The savings come from removing spaces, tabs, and newlines that add no data value.
When should I minify JSON?
Minify JSON for API responses (reduces bandwidth), configuration files in production, data storage (saves disk space), and network transmission. Keep formatted versions for development and debugging.
Does minification affect JSON parsing performance?
Minified JSON parses slightly faster because the parser processes fewer characters. The difference is negligible for small files but measurable for large datasets. More importantly, smaller files transfer faster over networks.
Can I minify JSON with comments?
Standard JSON does not support comments. If your JSON contains // or /* */ comments (JSONC format), the minifier removes them along with whitespace. The output is valid standard JSON.
