Jpeg to .psd?

Open the JPEG

Select "save as" and select PSD for file-type, now you can add layers if that’s what you are after.

So now it’s a PSD, but you cannot reverse the compression done when you did the original save as JPEG, sorry.

Imagine you took a complex novel, I'm gonna say war and Peace as an example.

You have it slimmed down like readers digest used to do. Simplifying the content significantly ("removing detail" and subtlety like the JPEG process does when it compresses an original

[the JPEG process discards up to 83% of original image content compared to a raw file].

You cannot now retrieve the original novel.

That’s why seasoned editors and image originators will mostly save the original - maybe as layered PSD, TIFF or even RAW and save only a copy as a JPEG.

Unless you did that your original is lost. 

Sorry

I hope this helps
