Today, I will show you how do I convert int to byte in golang, as mentioned above I’m going to use the binary.LittleEndian.PutUint32() method which is provided by the encoding/binary package.

Let’s start our Golang convert int to byte example

main.go

package main

import (
    "encoding/binary"
    "fmt"
)

func main() {
    bs := make([]byte, 4)
    binary.LittleEndian.PutUint32(bs, 31415926)
    fmt.Println(bs)
}

In the above example, we have converted the int value to a byte and printed in golang console. let’s check the output.
