Frequently Asked Questions

What does minifying do?

It removes spaces, tabs, and line breaks that are not needed, which makes the file smaller for storage or transfer.

Does it change the data?

No. The values are identical; only the formatting is removed.

When should I minify?

For production payloads and APIs where a smaller size helps. Use the prettifier while you read or edit by hand.

Is my data sent anywhere?

No. Everything runs in your browser, so the JSON you paste is never uploaded.

Is it free?

Yes. Every tool here is free to use with no sign up.
