Help?!? When I view my massive Jpegs at 100% I can see the pixels - is this normal?

This is just a very noisy image, probably shot at very high ISO (I use a D800 and this kind of noise usually doesn't happen until ISO 3200 and up).

ACR/Lightroom noise reduction should be able to reduce this significantly - but you need to do it. It doesn't happen automatically like it often does in camera manufacturers' own software.

Thank you - can I do this to the JPEG in Lightroom - the noise reduction thing? - I don’t have the original RAW file anymore. I wonder if doing it to the jpeg might make things worse?

Yes, it'll work. It won't be nearly as effective as with the original raw file - but it'll help.

I do not see pixels. You would have to go to 600% to see pixels as shown in my photo. The white lines are the Pixel Grid.

Screen Shot 2017-02-21 at 4.59.23 AM.png

At 100% you see some fuzziness, but that's the nature of the jpeg and as 21 pointed out, noise (not pixels).

Screen Shot 2017-02-21 at 5.06.53 AM.png

and at 12.5% like yours.

Screen Shot 2017-02-21 at 5.13.11 AM.png

My photo is 5312 px by 2988 px at 72 ppi

What do you see if you click on the white arrow at the bottom right and checkmark Document Dimensions?

Screen Shot 2017-02-21 at 5.20.10 AM.png

Admittedly not shot by a Nikon D800, but by a 16 MP Samsung Galaxy S6 Camera Phone.

Using the same units, mine is 27 x 15 cm @ 500 ppi.

Maybe you can try Noise Reduction as Dag Suggested, but printed out at that size, does it look bad?

I've never had any issues printing them out. It's a client query. I'll be sending them off to print and then send those to the client so they can see they are fine.
