Frequently Asked Questions
What does minifying JSON do to the output?
It strips all non-essential whitespace, newlines, and indentation, producing a compact single-line JSON string.
How much can minifying JSON reduce file size?
Savings depend on indentation depth, but heavily formatted JSON can shrink by 20–40% after minification.
When should I minify JSON for production use?
Minify JSON when serving API responses or config files over the network where bandwidth matters — it reduces transfer size and parse time.
What is the difference between JSON minify and JSON compress?
Minification removes whitespace at the text level; compression (like gzip) operates at the binary level and typically provides much greater size reduction.
Does minifying JSON change data or values?
No. Only formatting whitespace is removed — all keys, values, and structure remain identical.
Are my JSON inputs stored or logged when minifying?
No. The minifier runs in your browser with no server communication — your data is discarded when you leave the page.
