Base32 encoding represents binary data using 32 ASCII characters (A-Z and 2-7). It is useful when case-insensitive encoding is needed.
Base32 is case-insensitive and avoids ambiguous characters, making it ideal for manual entry and systems that don't preserve case. Base64 is more space-efficient.
No, Base32 encoding is performed entirely in your browser. Your input text is encoded locally with JavaScript and never transmitted anywhere.
