Description
Name: Joint Photographics Experts Group File Interchange Format
Extension: JFIF, JFI, JPG, JIF and JFIF
Type: Raster format
Colors: 1 to 24-bit
Color Modes: We provide your JPEG file in RGB mode. JPEG format also supports
CMYK, RGB, and Grayscale color modes.
Standard: ISO (IEC 10918)
Platforms: DOS, Windows, Macintosh and UNIX
Joint Photographic Experts Group (JPEG) format is
commonly used to display photographs and other continuous-tone images
in hypertext markup language (HTML) documents over the World Wide Web
and other online services. JPEG format supports CMYK, RGB, and Grayscale
color modes, and does not support alpha channels. Unlike GIF format,
JPEG retains all color information in an RGB image but compresses file
size by selectively discarding data.
A JPEG image is automatically decompressed when opened.
A higher level of compression results in lower image quality, and a
lower level of compression results in better image quality. In most
cases, the Maximum quality option produces a result indistinguishable
from the original.
Purpose
Due to its highly efficient way of compressing images it is mostly used for
large photos.
JPG is the most common format on the Internet. Images with a maximum of 256
colors should instead be stored as GIF, which have a more efficient way of
compressing these images.
Advantages
The format offers a very good compression, especially for photos. The compression
will reduce the file size by approx. 5 to 20 times.
Since the format has been so widely used on the Internet you will find support
for the format in most software.
ISO-standard
Disadvantages
The format uses a Lossy compression. This means that you will loose information
every time you save the image. You should not use JPG as a master copy of
your images.
The compression is set differently in different software,
sometimes from 1–100, 100–1, 1–5, low–max.
This makes it somewhat confusing when you save the image.

Name: Graphics Interchange Format
Extension: GIF
Type: Raster format
Compression: LZW
Colors: 1 to 8 bit-color (Max 256 colors)
Versions: GIF87a and GIF89a
Standard: CompuServe Incorporated
Platforms: DOS, Windows, Macintosh and UNIX
Graphics Interchange Format (GIF) is the file format
commonly used to display indexed-color graphics and images in hypertext
markup language (HTML) documents over the World Wide Web and other
online services. GIF is an LZW-compressed format designed to minimize
file size and electronic transfer time. GIF format preserves transparency
in indexed-color images; however, it does not support alpha channels.
Overview
GIF is in most cases used for screen presentation. It can also be used as animated
GIF. This means that you store several images in the file and these are exchanged
at specified time intervals. These changes make it look like an animation.
Animated images should be avoided if the user intend to print the page.
Purpose
GIF should be used on the Internet if the image only requires 256 colors. Images
that have more than 256 colors should be saved as JPEG.
Advantages
Most image software can import and export GIF-files.
The file format offers extremely small files, which gives fast download and
display on the net etc.
Disadvantages
Only 256 colors can be stored in the file which means that you can hardly use
it for photos without great quality loss.

Name: Tag Image File Format
Extension: TIF, TIFF
Type: Raster format
Colors: 1 to 24-bit
Color Spaces: We provide your TIF in RGB mode. TifF formats also support Grayscale,
RGB, CMYK, YCbCr and CIELab
Versions: 1–6 (1992)
Compression: LZW (Lempel-Ziv-Welch), RLE, CCITT group 3 and 4, JPEG or Uncompressed
Standard: Adobe
Platforms: DOS, Windows, Macintosh and UNIX
Tagged-Image File Format (TIF) is used to exchange
files between applications and computer platforms. TIF is a flexible
bitmap image format supported by virtually all paint, image-editing,
and page-layout applications. Also, virtually all desktop scanners
can produce TIF images.
TIF format supports CMYK, RGB, Lab, indexed-color,
and grayscale images with alpha channels and Bitmap-mode images without
alpha channels.
Purpose
Platform independent format for photos etc. TIFF has become a defacto-standard
for raster images.
Advantages
Platform independent (DOS, PC, Mac and UNIX)
The format is supported in almost every image and word processing software.
TIFF is one of the most common formats.
Disadvantages
Large images require large storage space and takes a long time to download.
