PNG export options
When you export artwork to PNG format, you can set the following options:
Resolution Determines the resolution of the rasterized image. Higher resolution values result in better image quality
but larger file sizes.
Note: Some applications open PNG files at 72 ppi, regardless of the resolution you specify. In such applications, the
dimensions of the image will be altered. (For example, artwork saved at 150 ppi will be over twice as large as artwork
saved at 72 ppi.) Therefore, only change the resolution when you know the target application supports non-72-ppi resolu-
tions.
Color Specifies a color for filling transparency. Choose Transparent to preserve transparency, White to fill trans-
parency with white, Black to fill transparency with black, or Other to select another color for filling transparency.
Anti-Alias Removes jagged edges in the artwork by supersampling it. Deselecting this option helps maintain the hard
edges of line art when it is rasterized.
Interlaced Displays low-resolution versions of the image as the file downloads in a browser. Interlacing makes
download time seem shorter, but also increases file size.

TIFF export options
When you export artwork to TIFF format, you can set the following options:
Color Model Determines the color model of the exported file.
Resolution Determines the resolution of the rasterized image. Higher resolution values result in better image quality
but larger file sizes.
Anti-Alias Removes jagged edges in the artwork by supersampling it. Deselecting this option helps maintain the hard
edges of line art when it is rasterized.
LZW Compression Applies LZW compression, a lossless compression method that does not discard detail from the
image. Select this option to produce a smaller file.
Byte Order Determines the appropriate sequence of bytes for writing the image file, based on the platform you
choose. Illustrator and most recent applications can read files using the byte order for either platform. However, if
you don’t know what kind of program the file may be opened in, select the platform on which the file will be read.
Embed ICC Profiles Creates a color-managed document.
