FAQ

When should I use Base32 vs Base64?
Base32 is case-insensitive and avoids visually-confusing characters — used for OTP secrets, sharing over voice, or QR codes.
Why does Base58 skip certain letters?
Base58 was designed for Bitcoin addresses to avoid visually ambiguous characters — it removes 0, O, I, and l so printed or hand-written codes are easier to read without mistakes.
Is my input data sent anywhere?
No — all encoding and decoding happens locally in your browser. Nothing is uploaded, logged, or transmitted to any server.
