What is a suggested method of converting .bin to hex to send over serial to extra MCU?

So, if the ESP32 is the air interface for some MCU, and I want to upload it over serial...what is the best way to convert it from bin to hex to send over?
Has anyone done this yet?

not sure i understand you right.
you want use the esp32 for send bin files over the air to the serial of an MCU, you want use for this then the esp32 as a "air2serialflasher" ?
and for this you want convert the bin file for the MCU to send it over the air (esp32) to the MCU serial as a hex file ?

Do you mean from the server to the ESP32, or from the ESP32 to the additional MCU?
