What Is Minify?

JSON Minification is the process of removing all unnecessary characters from JSON data—such as spaces, tabs, and line breaks—without altering its meaning or structure. Minified JSON files are smaller in size, which reduces bandwidth consumption and improves load times in web applications.

Input
{
  "name": "John",
  "age": 30
}
Output
{"name":"John","age":30}
