Zamicol's Base Converter
If your project needs to do base conversion, use base_convert.js.
BaseConverter is a generalized, number first converter. This converter treats input and output as numbers and uses the iterative divide by radix conversion method. This method is suitable for arbitrary bases, character sets, and alphabet lengths.
Surprisingly, I couldn't find a converter online that met my needs, so I built this. Other projects had limitations on alphabet characters, alphabet length, input/output length, or were designed for specific encoding.
Padding can be applied according to bytes, nibbles, or any other bucket size. This converter is alphabet agnostic for input and output and has no limitations on alphabets starting with 0, special or repeating characters, or is unable to be divided evenly.
