JPEG (Joint Photographic Experts Group) is a way to store images by compressing digital images, especially for natural or real scenes. However, it is not suite for online drawings and cartoons. When compressing images, some information will be lost. But human eyes won’t find the inconspicuous difference. There are two types of JPEG formats which are full-colored (stores 24 bits per pixel) and grayscale (stores 8 bits per pixel). Transparency or animation can’t be displayed by JPEGs.
JPG/JPEG Photo Converter
is a wonderful tool to convert many
photo formats such as BMP, GIF, PNG,
TIF, ICO, EXIF, WMF, EMF to JPG/JPEG
file with some useful parameters
changed. It resizes the original
photo's width or height, and has a
convenient proportional calculator
to keep aspect ratio on a fly. It
controls JPEG compression quality so
as to change the photo file size. It
can rotate or flip photo, add the
your favorite text or watermark to
photo. It also converts a frame of
animated photo to a jpg file.

Graphics Interchange Format (GIF) is
a useful 8-bit-per-pixel bitmap
image format created by CompuServe
in 1987. Since then it has become
wide used for its wide support and
portability. GIF supports online
drawings, pictures with blocks of
solid colors, and pictures with
sharp boundaries between colors. GIF
is unsuitable for photographs due to
its 256 distinct colors from the
over 16 million representable in
24-bit RGB limitation. However,
there is a hack that can overcome
this limitation under certain
circumstances. On the process of
compressing, there is no information
lost in GIF files. |
