Introduction
JPEG Artifacts
What Are JPEG Compression Artifacts?
Topaz DeJPEG
JPEG compression artifacts are random and unwanted
image distortions that appear in JPEG images. Most often, JPEG artifacts appear in photos as blocks, dots and
fringes. These artifacts are also referred to as: Checkerboarding, and mosquito noise.
To see if your images are being aected by JPEG artifacts because of compression, zoom in on the image
and look for areas with checkerboard patterns, mosquito noise, fuzziness, reduced detail, reduced clarity
or uneven color.
What Causes JPEG Compression Artifacts?
JPEG compression artifacts are caused by the compression that occurs when you save an image in the jpeg
format. JPEG images can be saved at dierent levels of
compression and quality. Using a higher compression
produces a lower-quality image and a smaller image
size. Using a lower compression produces a higherquality image and a larger le size.
Benets and Consequences of the JPEG Format
Using the JPEG image format is popular because it reduces le sizes and allows for increased storage. Most
web images are JPEGs for this very reason. However
using the JPEG format also comes with unwanted and
typically irreversible side eects. The JPEG format is a
lossy form of compression, and as a result, image quality is lost and artifacts are introduced. Rhe quality that
is lost from compression cannot be restored and
8
will continue to diminish in quality every time you edit
and save the image in the JPEG format.
Why can’t I use a Noise Reduction Program to Remove
JPEG Compression Artifacts?
Noise reduction algorithms are not eective at removing JPEG artifacts caused by lossy compression methods because images noise is not the same as compression artifacts. Programs specialized in JPEG artifact
elimination can easily target artifacts, successfully
remove them and drastically improve your image with
precision.
