What is Base32?

Base32 is a base-32 encoding scheme that uses the 26 letters A-Z and digits 2-7. It is defined in RFC 4648 and is commonly used for encoding binary data in email (DNSSEC), cryptocurrency addresses, and QR codes. Our tool encodes text to Base32 and decodes Base32 back to text. It uses padding (=) to ensure the output length is a multiple of 8. Base32 is more compact than Base64 but still human-readable.

📌 How to Use

Click "Encode to Base32".
