How to store array of bytes in database?

Question

Database

Hi!
On the client (js) there is an array of bytes. For example: [104,236,116,246] (4 bytes here).
You need to transfer this array to the server and store it in the database.
Converting an array to json, passing it and storing it as a string is not rational (now one 1 byte takes 3 bytes).
You can convert each byte to a UTF-8 character, for example. But I don't think it's reliable.
How to implement it correctly?
Thank you.
