Binary File size very big

I try to generate binary file, but the generated file size is very big.

For example, the "quickstart_ek_ra2l1_ep" project, the HEX file is 74k, SREC file size is 79k, but binary file size is 16,449k.

I change the output file format via: "C/C++ build" =>"Setting" =>"GNU ARM Cross Create Flash Image" =>"Output file format" =>select "RAW binary".

Is there other way to converter file to Binary?
