Choose Float or Integer depending on your image and the result you want. Integer is usually the best option for an

around the edges.
Tile Size
Specifies the size of the tiles used in the image. When you use low quality values to optimize images smaller
than 1024 x 1024 pixels, using the largest tile size produces better results.
A tile size of 1024 is best for most images. When creating files with small dimensions (for cell phones, and so forth),
use a smaller tile size.

full size.
Progressive

Makes the image appear first as a grayscale image, then as a color image.
Region Of Interest
Lets you choose an alpha channel to define a region of interest if your Photoshop document
contains one or more alpha channels.
After the alpha channel is loaded as a region of interest, choose an Enhance value to increase or decrease the quality
of the region of interest relative to the rest of the image. Note that Enhance does not change the file size of the image,
so enhancing the area inside the alpha channel decreases the quality of the area outside the alpha channel (and vice
versa).
