What are artifacts in JPEG?

JPEG artifacts are caused by compression when an image is saved in the . jpg format. Each time an image is saved in this format it is compressed and “non-essential” data is discarded. The result of compression is that an image can suffer from blockiness, mosquito noise (around edges) and color degradation.

How do I fix a compression on a JPEG?

To Remove JPEG Compression Artifacts you need to start by converting your Background layer into a non-destructive file. To do this, right-click on the layer and select Convert to Smart Object. Next, go to Filter > Noise > Reduce Noise.
