Upload multiple documents into Document library

How do we upload multiple documents into Document library in Share Point? 

In the Share point application upload multiple options appears only in Internet Application. It is very important to have these features because to upload a huge number of files into the application is very tedious and repetitive process. To avoid this “Upload Multiple Files” would be very useful.

2. Below the browse field there will be an option to “Upload Multiple Files”

3. Drag and drop multiple content in the popup shown

4. Click on “Add”
