Question 1

Is the Base32 converter free?

Accepted Answer

Yes. Encode and decode unlimited text with no account.

Question 2

What is Base32 used for?

Accepted Answer

Authenticator app secrets (TOTP), API tokens, and anywhere a case-insensitive, human-friendly encoding of binary data is needed.

Question 3

Is my secret safe when I paste it here?

Accepted Answer

Yes. Encoding and decoding run entirely in your browser, so your secrets never leave your device.

Question 4

What is the difference between Base32 and Base64?

Accepted Answer

Base32 uses a 32-character alphabet (A-Z, 2-7), making it case-insensitive and easier to read aloud. Base64 is more compact but case-sensitive.

Question 5

Why does my decoded output look wrong?

Accepted Answer

Base32 requires padding with = and a valid alphabet. The tool validates input and reports exactly what is malformed.

Question 6

Can I decode a Google Authenticator secret here?

Accepted Answer

Yes. Paste the Base32 secret to decode it, though keep in mind anyone with the secret can generate your codes, so never share it.
