About online online Base32 encode and decode
hidevtool Base32 encodes UTF-8 bytes with the RFC 4648 alphabet (A–Z and 2–7)—common for secrets, tokens, and some OTP-related strings.
Paste text to encode or a Base32 string to decode; padding equals signs are optional on input.
Online Base32 encode & decode capabilities
UTF-8 to Base32
Encode packs bits into 5-bit groups mapped to the standard Base32 alphabet.
Base32 to text
Decode ignores padding and whitespace, then rebuilds UTF-8 bytes when the alphabet is valid.
Common use cases
How is Base32 different from Base64?
Base32 uses a smaller alphabet (case-insensitive letters and digits 2–7) and produces longer strings but avoids punctuation.
How do I encode text to Base32 online?
Paste UTF-8 text and click Encode to get a Base32 string.
How do I decode Base32?
Paste the Base32 payload and click Decode. Invalid characters show an error.
