Get ProHow it works
3 steps, no account. It runs in your browser and nothing is uploaded.
Enter text or a file
Type or paste anything, or drop a file onto the input; the Base32 updates with every keystroke.
Choose the form
With or without padding: pick in the bar and the result is rewritten in place.
Copy, download or swap
Copy the Base32, download it as a text file, or press Swap to decode it back.
Where Base32 is used
Case-insensitive and free of look-alike digits, at 60% larger than the bytes. Where Base32 does its work.
TOTP secrets
The secret inside an authenticator's QR code is Base32: `otpauth://totp/…?secret=JBSWY3DPEHPK3PXP`.
Tor onion addresses
A v3 onion address is 56 Base32 characters: the service's public key, a checksum and a version.
Case-insensitive file systems
A hash as a file name has to survive Windows and macOS folding case; Base32 does and Base64 doesn't.
DNS
DNS labels are case-insensitive, so binary data in a hostname (DNSSEC NSEC3, some tunnels) is Base32.
Codes people type
No 0, O, 1, l or 8, so a licence key or a recovery code read aloud comes back right.
ULIDs
ULIDs use Crockford's Base32, a variant with digits first, for a sortable 26-character id.
