Frequently Asked Questions

Base32 vs Base64?+

Base32 is longer but uses a smaller, case-insensitive alphabet, so it is safer for names, codes and QR secrets.

Why does decoding fail?+

The text contains characters outside A–Z and 2–7. Remove spaces or typos and try again.

Is my data safe?+

Yes. Everything runs inside your own browser. Your text, files and images are never uploaded to any server.
