Are the UUIDs random?

Yes — they use your browser's cryptographically secure random source (crypto.randomUUID). Nothing is sent anywhere.

Is my file uploaded to a server?

No. This tool runs entirely in your browser. You can open your browser's network tab and verify no request carries your file.
