Hexadecimal Decimal Binary and Octal Converter

I was in the midst of converting "manually" from hexa to binary, regroup the binaries, and convert it to decimal, then check on the Base64 index table to get the "characters" for some comparison to prepare this post. I found this website.

Thanks to this web site, it can directly convert from any base of number to the other base. I can save my brain power in this. :D
