jpeg artifacts

A kind of compression artifact. These can be visible as blockiness and noise (mosquito noise), and are usually seen in areas with high contrast, such as near lines.

This tag should be used for images where these artifacts are noticeable when viewed normally, without zooming in or enhancing the contrast.
