Use this tool to quickly decode base-62 text-printable characters to a readable string.

What is Base 62 decode

Base 62 is not for encryption purposes and is not secure. It is an encoding mechanism only.

Decodes a string so that it conforms to the Base62 Data Encodings specification. Base62 encoded data is a string of character that contains only a-z, A-Z, 0-9. The string contains text-printable characters.

alphanumeric = 0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz

Base62 Character Encoding

Base62 can encode any binary data! Since binary data, typically unreadable by humans, is the result of most cryptographic operations, an encoding strategy is required to convert the zeroes and ones into something that can be recorded or shared with others.

When converting a Base 10 integer to its Base 62 encoding, URL shortening often uses the Base62 encoding. Base62 is similar to Base64, except that it does not have the +, /, and = symbols. Base62 comprises 62 characters, 26 upper letters from A to Z, 26 lower letters from a to z, and 10 integers from 0 to 9.

Many URL shorteners use a Base 62 algorithm.

The decoding principle

The technique for Base62 decoding as follows:

• parse the representation using base 62 and a special alphabet
• convert that Integer to a ByteArray

The 62 digit long alphabet to use is equal to

'0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'
