How Base32 encoding works
Base32 maps every 5 bits of input to one character from A–Z and 2–7, which keeps the alphabet case-insensitive and free of visually ambiguous digits.
Base32 Text Encoder
Encode UTF-8 text as RFC 4648 Base32. Runs entirely in your browser — input is never uploaded.

Padding and case
Encoded output is padded to a multiple of 8 characters with =. Decoding here is case-insensitive and accepts input with or without padding.
Frequently asked questions
Base32 output is about 60% larger than the input — larger than Base64 — in exchange for being safe to read aloud or type by hand.
