JPEG (Joint Photographic Experts Group) Commonly used to save photographs. JPEG format retains all color infor-
mation in an image but compresses file size by selectively discarding data. JPEG is a standard format for displaying
images over the web. For more information, see “JPEG export options” on page 273. You can also save an image as a
JPEG file using the Save For Web & Devices command.
Note: Artifacts, such as wave-like patterns or blocky areas of banding, are added to a file each time you save the file as
a JPEG. Always save JPEG files from the original image, not from a previously saved JPEG.
Macintosh PICT Used with Mac OS graphics and page-layout applications to transfer images between applications.
PICT is especially effective at compressing images with large areas of solid color.
Flash (SWF) A vector-based graphics format for interactive, animated web graphics. You can export artwork to the
Flash (SWF) format for use in web design, and view the artwork in any browser equipped with the Flash Player
plug-in. For more information, see “Flash export options” on page 271. You can also save an image as an SWF file
using the Save For Web & Devices command (see “SWF optimization options (Illustrator)” on page 395), and you
can export text as Flash Dynamic or Input text (see “Tag text for export to Flash” on page 331). In addition to
exporting artwork in Flash format, you can copy Illustrator artwork and paste it into Flash. The fidelity of artwork
is maintained across the clipboard.
Photoshop (PSD) The standard Photoshop format. If your artwork contains data that cannot be exported to
Photoshop format, Illustrator preserves the appearance of the artwork by merging the layers in the document or by
rasterizing the artwork. As a result, there may be times when layers, sublayers, compound shapes, and editable text
are not preserved in the Photoshop file, even though you selected the appropriate export option. For more infor-
mation, see “Photoshop export options” on page 274.
PNG (Portable Network Graphics) Used for lossless compression and for display of images on the web. Unlike GIF,
PNG supports 24-bit images and produces background transparency without jagged edges; however, some web
browsers do not support PNG images. PNG preserves transparency in grayscale and RGB images. For more infor-
mation, see “PNG export options” on page 275. You can also save an image as a PNG file using the Save For Web &
Devices command.
Targa (TGA) Designed for use on systems that use the Truevision® video board. You can specify a color model,
resolution, and anti-alias setting for rasterizing the artwork, as well as a bit depth to determine the total number of
colors (or shades of gray) that the image can contain.
Text Format (TXT) Used to export text in an illustration to a text file. (See “Export text to a text file” on page 331.)
TIFF (Tagged-Image File Format) Used to exchange files between applications and computer platforms. TIFF is a
flexible bitmap image format supported by most paint, image-editing, and page-layout applications. Most desktop
scanners can produce TIFF files. For more information, see “TIFF export options” on page 275.
Windows Metafile (WMF) An intermediate exchange format for 16-bit Windows applications. WMF format is
supported by almost all Windows drawing and layout programs. However, it has limited vector graphics support, and
wherever possible, EMF format should be used in place of WMF format.
