Convert auto and layer-based slices to user slices

A layer-based slice is tied to the pixel content of a layer, so the only way to move, combine, divide, resize, and align it is to edit the layer—unless you convert it to a user slice.

All auto slices in an image are linked and share the same optimization settings. If you want to set different optimization settings for an auto slice, you need to promote it to a user slice.

  1. Using the Slice Select tool, select one or more slices to convert.
  2. Click Promote in the options bar.
    You can promote an auto slice in the Save For Web & Devices dialog box by unlinking it. See Work with slices in the Save For Web & Devices dialog box
