GIF format



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.

You can save an image as one or more GIF files using the Save for Web command. (See Optimizing images.)

To save a file in GIF format:

1 Choose File > Save As, and choose CompuServe GIF Format from the format list.

2 If necessary, deselect the Layers as Frames option.

3 Specify a filename and location, and click Save.

4 For RGB images, the Indexed Color dialog box appears. Specify conversion options as described in Choosing a color mode, and click OK.

5 Select a row order for the GIF file and click OK:

  • Normal to create an image that displays in a browser only when it is fully downloaded.
  • Interlaced to create an image that displays as low-resolution versions in a browser while the full image file is downloading. Interlacing can make downloading time seem shorter and assures viewers that downloading is in progress. However, interlacing also increases file size.

  • To save an animated GIF file:

    1 Choose File > Save As, and choose CompuServe GIF from the format list.

    2 Select the Layers as Frames option, specify a filename and location, and click Save.

    When the Save GIF dialog box appears, set optimization options as described in Optimizing images. If necessary, select Animate. Then set the animation options as described in Creating animated GIFs.

    3 Click OK to save the file.
