Remove edits from pictures

Question

How do we remove edits from a picture, specific to remove a black bar which was added on top via MS Paint?

Answer 1

As you said, it's a JPEG file. You can only remove a black part if the file has layers: whatever is underneath the black part needs to be stored in the file as well. For JPEG files that's not the case: the black part has simply replaced the previous content so it's no longer part of the file. So it's not possible in this situation.

Answer 2

its simple open the image in Photoshop select the area which you want to keep...with the help of marquee tool. then crop the whole image{go to top bar then image>crop} and save...and you are done
