Preserve background transparency in a GIF or PNG image

GIF and PNG‑8 formats support one level of transparency—pixels can be fully transparent or fully opaque, but not partially transparent. (By contrast, PNG‑24 format supports multilevel transparency; that is, you can have up to 256 degrees of transparency in an image, ranging from opaque to completely transparent.)

  1. Open or create an image that contains transparency, and choose File > Save For Web.
  2. In the Save For Web dialog box, select GIF, PNG‑8, or PNG‑24 as the optimization format.
  3. Select Transparency.
  4. For the GIF and PNG‑8 formats, specify how to treat partially transparent pixels in the original image. You can blend these pixels with a matte color, or you can create hard-edged transparency by applying a matte setting of None.
