Are my files uploaded to a server?
Never. Every tool runs inside your browser using WebAssembly and Web Workers. Your files stay on your device and are wiped from memory as soon as you download the result.
Is the randomness secure?
Yes. Values come from crypto.getRandomValues, the browser's cryptographically secure generator, with unbiased sampling.
