Encode text to Base32 or decode Base32 back to text, following RFC 4648. Runs in your browser.
Base32 encodes binary data using 32 characters (A–Z and 2–7). It's case-insensitive and avoids easily-confused characters, so it's common in TOTP secrets, file names and URLs.
Base64 uses 64 characters and is more compact, but is case-sensitive and includes symbols. Base32 is longer but safer for case-insensitive, human-readable contexts.
No. Encoding and decoding run entirely in your browser.
