What is the best way to download YouTube videos for free?

Today, I will talk about How we can download any www.youtube.com video without paying any cost. So lets start....I think this is probably the easiest way to download any YouTube video without any software any paying cost.  You have to just follow some steps:

STEP 1 : Open www.youtube.com in Google Chrome OR any its up to you, which browser you are using.

STEP 2 : Open the video that you want to download from www.youtube.com.

STEP 3 : Go to url and type ss before y.

Example-

Original URL : https://www.youtube.com/watch?v=GNS9L57xsbA
Modified URL : https://www.ssyoutube.com/watch?v=GNS9L57xsbA

After doing that, press enter ↵, a website en.savefrom.net will be appear on your screen with saving options. 

STEP 4 : Select the extension of the video you want to download and click on download.

Thats it..... :) :):):) Enjoy with your video.
