Post(), TIdHTTP will decode the raw bytes to Unicode (using any number of 
charsets, none of which are suiable for binary data), and then you are 
assigning that Unicode string to an AnsiString, which will convert the 
Unicode data to the OS default Ansi codepage, which is also not suitable for 
binary data, either.


Why are you receiving a binary file as a String to begin with?  You should 
be using the overloaded version of Post() that has an AResponseContent 
output parameter instead.  That way, you receive the raw bytes unaltered and 
unprocessed.  For example:


{code:delphi}
var
    msHttpResult : TMemoryStream;
    slPostData : TStringList;
begin
    ...
    slPostData := TStringList.Create;
    try
        // Fill in the TStringlist with the post data here...
        msHttpResult := TMemoryStream.Create;
        try
            IdHttp.Post(aHttpRequestData.sURL, slPostData, msHttpResult);
            msHttpResult.Position := 0;
            // use msHttpResult as needed...
        finally
            msHttpResult.Free;
        end;
    finally
        slPostData.Free;
    end;
end;
{code}
