Chapter 13: Saving and Exporting Images
dobe Photoshop supports a variety of file
formats to suit a wide range of output
needs. You can save or export your image
to any of these formats. You can also use Photo-shop
features such as clipping paths when placing
images in other applications.
File format and export choices appear either in the
Save As or Save a Copy dialog box or in the Export
menu. If a file format does not appear, install the
format’s plug-in module following the instruc-tions
in “Using plug-in modules” on page 31. For
information on a specific format, see “About file
formats” on page 318.
Saving files
Adobe Photoshop provides several ways for you to
save files: The Save command saves the file in its current
file format. The Save As command lets you save an alternate
version of the file in a different format. The Save a
Copy command lets you save an iden-tical
or flattened copy of the file. This command
leaves the original file intact.
Note: Some formats are available only for certain
color modes. For example, PixelPaint ™ (Macintosh)
is available for indexed-color and grayscale images.
In addition, many formats are available only if an
image has no additional layers or alpha channels.
To save a file in its current format:
Choose File > Save.
To save a file in a different file format:
1 Choose File > Save As.
2 For Format (Macintosh) or Save As (Windows),
choose a format. Unavailable formats are dimmed
(Macintosh) or not visible (Windows).
3 Type a filename, and choose a location for the
file.
4 Click Save.
With some image formats, a dialog box appears.
For information on the options available for
specific file formats, see “About file formats” on
page 318.
To save a duplicate of a file:
1 Choose File > Save a Copy.

2 For Format (Macintosh) or Save As (Windows),
choose a format.
3 To flatten all visible layers, select Flatten Image.
See “Flattening all layers” on page 271 for informa-tion
on flattened images.
4 To remove alpha channels from the image,
select Don’t Include Alpha Channels.
5 Click Save.
Note: To copy an image without saving it to your
hard disk, use the Duplicate command. See “Dupli-cating
images” on page 174 for more information.
Using image previews on the Macintosh
On the Macintosh, you can choose to save your
files with the following types of image previews:
File icons are the preview icons you see on the
desktop. Thumbnails are the image previews that appear
in the Open dialog box. Full size previews are images intended for use in
applications that open Adobe Photoshop images
but require 72 ppi images. For non-EPS files, this
is a PICT preview.
The Full Size preview option is off by default.
Turning off the other preview options can make
saving faster and requires less file storage space on
your disk.
To set options for image previews:
1 Choose File > Preferences > Saving Files.
2 For Image Previews, choose one of the following
options: Never Save to save files without previews. Always Save to save files with the specified
preview or previews. Ask When Saving to assign previews on a file-by-file
basis when you save.
3 If you chose Always Save, select the preview or
previews you want to use.
4 Click OK.
Using image previews in Windows
In Windows, you can choose to save images with a
thumbnail preview that appears in the Open dia-log
box. In Windows NT 4.0 and Windows 95, you
can also generate preview icons for files that have
been saved.
To set options for thumbnail previews:
1 Choose File > Preferences > Saving Files.

2 For Image Previews, choose one of the following
options: Never Save to save files without previews. Always Save to save files with the specified
preview or previews. Ask When Saving to assign previews on a file-by-file
basis when you save.
3 Click OK.
To generate a preview icon for a file (Windows NT 4.0
and Windows 95 only):
1 Save the file.
2 Choose File > Save As.
3 Position the pointer on the filename in the file
list, click the right mouse button, and choose
Properties from the context menu that appears.
4 Click the Photoshop Image tab.
5 For Icon Thumbnails, select the desired preview
icon. To have the file appear without a preview
icon, select Don’t Generate.
6 Click OK.
Using file extensions (Macintosh only)
On the Macintosh, you can have Adobe Photoshop
append the file extension to the name of a file
when you save it. This three-character file exten-sion
refers to the file’s format (for example, the
extension for a JPEG file is .jpg). Saving files with
extensions is useful when you want to use the files
on a system running Windows.
To append file extensions to filenames:
1 Choose File > Preferences > Saving Files.
2 For Append File Extension, choose one of the
following options: Never to save files without file extensions. Always to append file extensions to filenames. Ask When Saving to append file extensions on a
file-by-file basis when you save.
3 Click OK.
Saving files without extra alpha channels
When saving, Adobe Photoshop always preserves
the alpha channels in your image if the file format
supports it. If your target application requires that
these alpha channels be removed to properly read
the file, choose File > Save a Copy to create a new
file, select Don’t Include Alpha Channels, and save
the file.
Adding file information
Adobe Photoshop supports the information stan-dard
developed by the Newspaper Association of
America (NAA) and the International Press Tele-communications
Council (IPTC) to identify
transmitted text and images. This standard
includes entries for captions, keywords, categories,
credits, and original.The captions and keyword
entries can also be searched by some third-party
image browsers.
On the Macintosh, you can add file information to
files saved in any format. In Windows, you can add
file information to files saved in the Photoshop,
TIFF, and JPEG formats.
