How is Base32 different from Base64? Base32 uses 32 characters (A-Z and 2-7) and is case-insensitive, making it suitable for systems that don’t distinguish case.

When should I use Base32 vs Base64? Use Base32 when case sensitivity is a concern or for human-readable encoding. Use Base64 for more compact encoding.
