Hi Prakash,
May I suggest you Please read the given below points and follow below link with the help of below points and link you can solve your problem, it may be helpful to you. 

1. In below Link, you will find lightning component, js.controller, js.helper and apex controller as well, it is working fine in my Org.

2. Inside component -> <aura:attribute name="parentId" type="Id" default="0010o00002LMuvm" /> replace default Id with your record Id.

3. Inside js.helper -> MAX_FILE_SIZE: 4500000, //Max file size 4.5 MB, CHUNK_SIZE: 750000, you can replace the MAX_FILE_SIZE according to your requirement.

4. Js.controller and Apex controller will remain the same.

Follow below link for satisfying all the above points.
