About the JSON Minifier

Remove every unnecessary space and line break from a JSON document. The input is parsed first, so you also find out if it is invalid, and the output is guaranteed to be valid JSON.

• Validates while it minifies
• Reports how many bytes were saved
• Runs in your browser; the data is not uploaded

Frequently asked questions

Does minifying change the data?

No. Only whitespace outside strings is removed. Keys, values and their order stay the same.
