Falling under the category of raster
image files, JPEG is a compressed image file format widely used for
storing digital photographs and other images. The file type takes its
name from the Joint Photographic Experts Group (JPEG), and was developed
to provide a format that could support up to 24-bit color at relatively
smaller file sizes.
File Extension JPEG Type Flexibility
Though the advantage of compressed file
size make JPEG a popular file format, the compression is lossy, and
original data is lost when an image is edited or resized. However, the
format offers the flexibility of choosing your image quality setting -
the higher the image quality, the larger the file. Conversely, lower
image quality produces a smaller file size with greater compression and
therefore greater loss of data. Data loss notwithstanding, small file
sizes and sheer ease of handling makes the JPEG format extremely popular
for sending images by email or for posting on the web: most digital
cameras save images as JPEG files by default.
JPEG File types are cross platform
In addition to flexibility in setting
image quality and file size, JPEG files are also cross-platform, and
display without noticeable differences whether viewed on a Mac or on a
PC. Applications that support JPEG files include Photoshop, Illustrator,
Microsoft Photo Editor, Paint and several others. JPEG is also supported
by Internet Explorer and other web browsers.
JPEG file extensions have lousy
compression quality
One of the major disadvantages of the
lossy compression is that editing a JPEG file results in compression
loss on each save. To overcome this, it is recommended that the file is
saved first as a bitmap image, or some other lossless file format,
edited, and then resaved as a JPEG file. JPEG compression works best
with photographic images and paintings that portray smooth variations of
color and tone. For graphics and line drawings with high contrast, non-lossy
file formats are more suitable.
Summary: The JPEG file format, named after the Joint Photographic
Experts Group, is a popular file format that compresses images to small,
easily manageable file sizes, and is extremely useful for displaying
images on the web. A brief guide.
