Saving as rasters
You have two basic options for Illustrator files that will be displayed in web pages. You can save them to a web-supported vector format such as the Flash SWF format or to SVG (Scalable Vector Graphics) format. Or you can save to a more widely supported raster format such as GIF, JPEG, or PNG.The downside of saving Illustrator files to raster format is that the files lose scalability, and you lose the ability to edit files saved to raster formats. For this reason, you’ll often want to save a version of files you export as rasters in Illustrator CS2. If you are saving a file for the web, all of the above options (SVG, SWF, GIF, JPEG, and PNG) are available from the Save for Web dialog box. Sometimes you need to save files destined for print output to a raster format. The TIFF file format is a widely supported format that retains data better than JPEG or GIF formats and is the favored raster format for print output.To export to TIFF or any other raster format, choose File > Export, and select a file format from the Format (Mac) or Save as File Type (Windows ®) drop-down menu in the Export dialog box
