Frequently asked questions

Yes. The JSON Formatter is completely free with no sign-up, no watermarks, no daily limits and no premium tier.
Are my files uploaded to a server?
No. FileStripe processes your files locally in your web browser using JavaScript. Nothing is uploaded, so the JSON Formatter is safe for private photos and confidential documents and even works offline once the page has loaded.

Yes. The JSON Formatter works in Safari, Chrome, Firefox, Edge and Samsung Internet on phones, tablets and computers. On a phone you can pick files from your photo library or files app and share the result straight to another app.
