Work with slices in the Save For Web & Devices dialog box

If your image contains multiple slices, you must specify the slices to be optimized. You can apply optimization settings to additional slices by linking the slices. Linked slices in GIF and PNG‑8 format share a color palette and dither pattern to prevent the appearance of seams between the slices.

  • To show or hide all slices, click the Toggle Slices Visibility button .
  • (Photoshop only) To show or hide auto slices, choose Hide Auto Slices from the Preview pop‑up menu.
  • To select slices in the Save For Web & Devices dialog box, choose the Slice Select tool , and then click a slice to select it. Shift-click or Shift-drag to select multiple slices.
    Note: In the Save For Web & Devices dialog box, unselected slices are dimmed. This does not affect the color of the final image.
  • To view slice options in the Save For Web & Devices dialog box, select the Slice Select tool, and double-click a slice.
  • To link slices, select two or more slices and choose Link Slices from the Optimize pop‑up menu  (to the right of the Preset menu). The link icon  appears on the linked slices.
  • To unlink a slice, select the slice, and then choose Unlink Slice from the Optimize pop‑up menu.
  • To unlink all slices in an image, choose Unlink All Slices from the Optimize pop‑up menu.
