I recovered deleted photos from my Galaxy Note7 and the images didn't come out too well. Is there a way to recover it with good quality?

I accidentally deleted a lot of pictures I took yesterday then recovered them using DiskDigger. Unfortunately my pictures came back with low so so quality and I was wondering if there were any free methods that can recover them in the same condition. Usually I have back ups on google drive ready but I just got this phone and forgot to set it up.
