Setting file saving options (Photoshop)

You can set a variety of file saving options in the Save As dialog box. The availability of options depends on the image you are saving and the selected file format. For example, if an image doesn't contain multiple layers, or if the selected file format doesn't support layers, the Layers option is dimmed.

As a Copy

Saves a copy of the file while keeping the current file open on your desktop.

Alpha Channels

Saves alpha channel information with the image. Disabling this option removes the alpha channels from the saved image.

Layers

Preserves all layers in the image. If this option is disabled or unavailable, all visible layers are flattened or merged (depending on the selected format).

Annotations

Saves annotations with the image.

Spot Colors

Saves spot channel information with the image. Disabling an option removes spot colors from the saved image.

Use Proof Setup, ICC Profile (Windows), or Embed Color Profile (Mac OS)

Creates a color-managed document. (See Embedding profiles in saved documents.)

Thumbnail (Windows)

Saves thumbnail data for the file. In order to select or deselect this option, you must choose Ask When Saving for the Image Previews option in the Preferences dialog box. For more information, see Setting preferences for saving files (Photoshop).

Image Previews options (Mac OS)

Saves thumbnail data for the file. Thumbnails display in the Open dialog box. You can set these image preview options: Icon to use the preview as a file icon on the desktop, Full Size to save a 72-ppi version for use in applications that can only open low-resolution Photoshop images, Macintosh Thumbnail to display the preview in the Open dialog box, and Windows Thumbnail to save a preview that can display on Windows systems. Keep in mind that Windows thumbnails increase the size of files as delivered by Web servers.

Use Lower Case Extension (Windows)

Makes the file extension lowercase.

File Extension options (Mac OS)

Specifies the format for file extensions. Select Append to add the format's extension to a filename and Use Lower Case to make the extension lowercase.

Important: To display image preview and file extension options when saving files in Mac OS, select Ask When Saving for the Image Previews option and the Append File Extension option in the Preferences dialog box. For more information, see Setting preferences for saving files (Photoshop).
