text to base58 encoder
Base58 is the encoding Bitcoin popularized for wallet addresses: it removes from Base64 the visually ambiguous characters (0, O, I, l) and also "+" and "/", which break in fonts or URLs. The result is safer to copy and type by hand.

Back to the original text.
Select the Binary format, keep the direction on Text → Code and type your text. Each character becomes an 8-bit group (for example, 'A' becomes 01000001), separated by spaces. For the reverse, paste the binary and switch the direction to Code → Text, it works with space-separated groups or with one continuous run of bits.
It's the same base alphabet. Real Bitcoin addresses use Base58Check, which adds a checksum before encoding; this translator performs plain Base58 encoding, without the Bitcoin-specific checksum.
It removes 0 (zero), O (uppercase O), I (uppercase i) and l (lowercase L), plus "+" and "/". That leaves 58 visually unambiguous alphanumeric characters.
Yes, Flickr uses a different ordering (lowercase before uppercase) for short URLs. This translator uses the Bitcoin alphabet by default, the most common one.
