Base32 Encode/Decode

Input

Length: 0

Output

Length: 0

How Base32 works

Grouping: input bytes are processed into 5-bit groups; every 5 bits map to one character.
Alphabet: RFC 4648 uses A–Z and 2–7 (32 symbols); output is uppercase by spec.
Padding: output length is a multiple of 8; = is appended when needed.
Whitespace: spaces/newlines are often ignored during decoding.
Purpose: representation for text channels; not encryption or compression.

How to Use

What this tool does

Encodes text to Base32 (RFC 4648) and decodes Base32 back to text. Uses the A–Z, 2–7 alphabet and = padding.

Steps

Enter text → Encode → get Base32.
Paste Base32 → Decode → restore text.
Swap/Copy/Clear as needed.

Example

Hello → JBSWY3DP

Notes
