Encode UTF-8 text as RFC 4648 Base32 or decode Base32 to text.
Type or paste on the left — the result updates as you type.
Accepts padded or unpadded input and checks unused bits. Invalid UTF-8 is rejected. This is encoding, not encryption.
Up to 100,000 UTF-16 units per input and 1,000,000 per result. See the supported formats and examples below.
