Base32 Information

• Base32 uses 32 characters (A-Z, 2-7 in standard variant) for encoding

• Output is approximately 60% longer than the original data

• More human-readable than Base64 and case-insensitive in most variants

• Crockford variant excludes ambiguous characters (0, 1, I, L, O)

• Commonly used in backup codes, TOTP secrets, and distributed systems

Frequently Asked Questions

What Base32 variants are supported?
Standard RFC 4648, Extended Hex (base32hex), Z-Base32, and Crockford Base32 variants are supported.
When should I use Base32 instead of Base64?
Use Base32 when you need case-insensitive encoding, human-readable strings, or compatibility with systems that prefer Base32.
What is the difference between variants?
Standard uses A-Z and 2-7, Extended Hex uses 0-9 and A-V, Crockford excludes ambiguous characters, and Z-Base32 uses a different alphabet.
Why is Base32 output longer than Base64?
Base32 uses 32 characters vs Base64's 64, so it needs more characters to represent the same data (about 60% longer).
