calculate hash of binary file consisting of certain bytes

I'm having trouble understanding the principle, on how to "manually" calculate a binary file which consist of certain bytes.

To put into an example:

I have this binary file consisting of these bytes.

2C F2 BA A3 0E 26 5A 3B 2A 1F 01 4A 01 66 60 02

How can I use my knowledge of binary files, bits, bytes, and hex to calculate this using these sites?

I'm aware of Endianness and I'm not sure if this applies here in some way.
