How to Remove JPEG Artifacts and Pixelization

JPEG uses the lossy compression (inexact approximation) technique which reduces the size of multimedia files making them easily transmitted content. This implies that some original information is lost, possibly affecting the image quality. JPEG artifact is the distortion in the multimedia files. Also, each time you save your JPEG images, the quality reduces subsequently. They are the unwanted side-effects of processing an image.

You can spot them when there is a subtle graduated color change in a large wash of color – e.g. in a clear sky or green meadows. You can see outlines of a specific color and they are the artifacts.

Image quality also depends on pixels/resolution – the smallest component of the digital image – used to create the image. They add details and provide more accurate representations of the original format. Sometimes, enlarging, resampling, and resizing JPEG images stretches the screen resolution which is again, one of the causes that reduce image quality.

Signs of distorted images:

• A blur of dots around the image’s edges
• Color degradation
• Variation in tone and color
• Images are split
• Fuzziness
• Image checkerboarding
• Loss of edge clarity
• Loss of sharpness

JPEG artifacts and Pixelization can ruin an otherwise perfect picture.
