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 Base58 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 Base58, download it as a text file, or press Swap to decode it back.
Where Base58 is used
Letters and digits without the four look-alikes: for values people copy by hand. Where Base58 does its work.
Bitcoin addresses
A legacy address is a version byte, a hash of the public key and a checksum, as Base58Check: `1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2`.
Private keys
A wallet import format key is the private key as Base58Check, 51 or 52 characters starting with 5, K or L.
IPFS content ids
A CIDv0 is a SHA-256 multihash as Base58: the `Qm…` strings every IPFS link carries.
Solana keys
A Solana public key is 32 bytes as Base58, 43 or 44 characters, with no checksum.
Short URLs
Flickr's short URLs are Base58 photo ids with the alphabet in a different order.
Ripple
Ripple's addresses start with r and use their own ordering of the same 58 characters.
