Base32 Encoder/Decoder
Encode text to Base32 or decode Base32 strings back to plain text. Uses the RFC 4648 standard alphabet (A-Z, 2-7) with padding.
How to Use Base32 Encoder/Decoder
The Base32 Encoder/Decoder converts text to and from Base32 encoding using the RFC 4648 standard alphabet (A-Z and 2-7). Base32 is commonly used in TOTP/HOTP authentication tokens, DNS records, and systems that need case-insensitive encoding. Switch between encode and decode modes, paste your input, and get instant results. The encoder adds standard padding with = characters. The decoder handles both padded and unpadded input. All processing happens in your browser with no data sent to any server.
