JSON Minifier

Strip whitespace from JSON to reduce its size for storage or transfer.

Paste formatted JSON to compress it down to the smallest valid representation — useful before storing it in a database field or sending it over the network.

Your files and text are processed locally in your browser — nothing is uploaded to a server.
