Frequently Asked Questions

What is Base32? ▼
Base32 encoding uses 32 ASCII characters (A-Z, 2-7) to represent binary data. Used in TOTP/2FA and DNS.
Is my data private? ▼
Yes. All encoding and decoding happens in your browser. No data is sent to any server.
When would I use Base32 vs Base64? ▼
Base32 is case-insensitive and avoids ambiguous characters, making it ideal for TOTP secrets and DNS records. Base64 is more compact and used for general binary encoding.
