Base32 Encode

Base32 Encode is a free online encoder that helps you encode UTF-8 text to RFC 4648 Base32; alphabet A-Z and 2-7, with = padding. Useful for TOTP secrets and DNS-safe identifiers. Base32 Encode uses 1 input field, returns 3 output values, and runs in your browser on the device.

Base32 Encode details

First, enter Text in Base32 Encode. Next, review Base32, Output length (chars), and Input length (bytes). Additionally, Base32 Encode uses 1 input field and 3 output blocks so the result is easy to scan and copy.

Convert any UTF-8 string into its Base32 representation using the standard RFC 4648 alphabet (A-Z, 2-7) with = padding. Base32 is widely used for TOTP / 2FA seeds (Google Authenticator, Authy), case-insensitive identifiers, and any context where you need a binary-safe encoding that avoids the I/1/O/0 confusion common in Base64. Encoding happens entirely in your browser; your text never leaves the page.
