Base32 is an encoding scheme defined in RFC 4648 that uses 32 characters (letters A–Z and digits 2–7). Unlike Base64, the Base32 alphabet is case-insensitive and contains no special characters, making it suitable for URLs, filenames, and human-readable identifiers.
.ip6.arpa DNS zone;The = characters at the end align the Base32 string length to a multiple of 8. RFC 4648 requires padding by default, but allows omitting it when the length is known in advance.
Padding characters (=) are appended to make the Base32 string length a multiple of 8. This helps certain algorithms process the data correctly. However, many modern systems work fine without padding. Disabling it is useful when exchanging data with legacy or non-standard implementations that do not expect the = suffix.
Base32 encodes raw bytes, not characters directly. Make sure your text is encoded as UTF-8 before Base32 encoding. Our tool automatically uses UTF-8 for non-Latin characters. When decoding, the recovered bytes will display as correct Cyrillic text only in a UTF-8 context — check the encoding settings of your target system.
Base32 uses 32 characters (A–Z and 2–7), while Base64 uses 64 characters including + and /. Base32 is case-insensitive and easier to type without errors, so it is commonly used for authentication keys (e.g. TOTP codes) and DNS-safe identifiers. Base64 is more compact and better suited for large binary payloads like file attachments or image data URIs.
