What is JSON Minification?
JSON minification removes all unnecessary whitespace, line breaks, and indentation from JSON data. The result is a single line of compact JSON that's identical in content but smaller in size. This is the opposite of JSON formatting/beautifying.
When to Minify JSON
Minified JSON is ideal for API payloads, configuration storage, and anywhere file size matters. Removing whitespace can reduce JSON size by 20-60% depending on the indentation level. Every byte counts when you're sending thousands of API responses per second or storing millions of JSON documents.
