About this tool
Everything JSON Redactor does happens on your own device. JSON Redactor parses JSON entirely in your browser, so large or deeply nested documents stay on your device.
Because parsing is local, sensitive payloads never leave the page. It behaves the same on desktop and mobile, with nothing stored remotely.
