Web export formats
GIF, JPEG, and PNG are graphic file formats that are
common in web development because they are highly
compressible, making for faster transfer across the
Internet. However, a graphic’s visual integrity can
vary from one format to another, depending upon
each format’s method of compression. Therefore, base
your choice of file format upon the design and use of
your graphic.
GIF
Graphics Interchange Format, or GIF, is the most
popular web graphic format. Although it can contain
only 256 colors, GIF offers good, lossless image
compression. Also, GIFs can contain a transparent area
and multiple frames for animation.
Compression
Lossless compression means that no image quality is lost
when an image is compressed. A GIF compresses by
scanning horizontally across a row of pixels, finding solid
areas of color, and then abbreviating identical areas of
pixels in the file. Therefore, images with repetitive areas
of solid color compress best when saved as GIFs. A GIF
is usually ideal for cartoon-like graphics, logos, graphics
with transparent areas, or animations.
Note: Dithering or anti-aliasing GIF images produces
larger files.
