FAQ About Base32 Encode
Why use Base32 instead of Base64?
Base32 is case-insensitive and doesn't use special characters, making it safer for filenames, DNS names, and human transcription.
Is Base32 the same as Base32Hex?
No. Standard Base32 uses A-Z and 2-7. Base32Hex (RFC 4648) uses 0-9 and A-V. Check which your system expects.
Is my data private?
Yes. All encoding and decoding happens in your browser. Nothing is uploaded.
