🔣 Base32 Encode / Decode

How it works

Base32 uses a 32‑character alphabet (A–Z, 2–7) and groups data into 5‑bit chunks. Every 5 bytes (40 bits) are encoded as 8 characters.

• Padding with = yields output length divisible by 8.
• RFC 4648 defines variants (Crockford, no padding, lowercase); this tool implements the standard alphabet with padding.
• Text is converted to UTF‑8 bytes before encoding; decoding reverses to text.

All conversion is local.

No streaming; large texts load into memory.
