one thing solved my issue for big images.

I added following code in function.php file. ( to remove the max resolution cap)

add_filter( 'big_image_size_threshold', '__return_false' );

this stopped the wordpress to resize the image. now the image is clear.

I dont understand regenerating all the image thumbnails. My apologies. 

What is this tool going to do about the new images which I will upload? will it resize all my images? i dont want to resize my previous images.

FYI (just in case) : Im uploading new image after making the changes to function.php and after activating the plugin. but still the image is blured.

please guide. Highly appreciate your help.

The original file (looks clear)

After uploading the same file it becomes hazzy and also the resolution changes when i select full image to display
