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 Base62 updates with every keystroke.
Read the status
The status line says how many bytes became how many characters, and by how much the text grew.
Copy, download or swap
Copy the Base62, download it as a text file, or press Swap to decode it back.
Where Base62 is used
All the letters and digits and no symbols: the alphabet of short URLs. Where Base62 does its work.
URL shorteners
A shortener turns a link's row id into six or seven Base62 characters: the slug in `bit.ly/3xYz9Ab`.
Short unique ids
A 64-bit id fits in eleven Base62 characters, a 128-bit one in 22, with nothing a URL or a form could break.
Invite codes
Invite codes and referral links read as a run of letters and digits, long enough to be hard to guess.
Tokens and keys
An API key is random bytes written as Base62, so it pastes into a header, a shell or a config file untouched.
Video ids
YouTube's eleven-character video ids are base64url, a cousin with - and _; many clones use Base62 for the same length.
Upload names
A random file name that must be safe on every file system and in every URL.
