Minify JSON

Minify JSON helps you compress and clean up your JSON data by stripping out unnecessary formatting like whitespace and line breaks. It’s great for reducing payload size, speeding up API responses, or just making JSON easier to store and send. You can paste your data or load a file, and the Minify JSON tool instantly gives you the smallest version possible optionally compacting arrays and removing extra spaces inside strings too.

What Minify JSON can do:

Minify JSON turns bulky JSON into a single-line string with no distractions. It’s ideal for production use, testing compressed payloads, or working with tight storage constraints. The tool also supports additional cleanup, like removing internal spaces from strings or compacting arrays down to their leanest form. You get total control, and the output updates as you type.

Example:

Before:

{
  "user": {
    "name": "Alice Smith",
    "roles": [ "admin", "editor" ]
  }
}

With all options on:

{"user":{"name":"AliceSmith","roles":["admin","editor"]}}

Common Use Cases:

Minify JSON is perfect for trimming down large config files, preparing data for APIs or HTTP transmission, and cleaning output from formatted editors. It gives you a fast, no-frills way to reduce JSON to the essentials.

Useful Tools & Suggestions:

Before shrinking things down, Validate JSON helps make sure the structure is solid so nothing breaks during minification. And if you ever need to expand it again, Prettify JSON brings it back into a readable format fast.
