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.
