Is my JSON data safe and private?
Privacy & Security
Yes! Your JSON data is completely safe.
All core features (formatting, validation, minification, schema checks) run entirely in your browser. AI-powered features send your JSON to our servers for processing.
Client-Side Processing
All essential JSON operations happen locally on your device:
-
Formatting: Processed locally, never sent to servers
-
Minifying: Performed in your browser
-
Validation: Syntax checking happens client-side
-
Schema validation: Validated locally using Ajv library
