Figure out the best file format for your task

When you save your document, data and workbooks, or presentation as a Web page in Hypertext Markup Language (HTML) format, all graphics (including drawing objects and pictures) are saved in GIF, JPEG, or PNG format so that they can be viewed in a Web browser.

If you reopen the Web page in Word, Excel, or PowerPoint, the graphics will be in their original file formats so that you can still edit them as you normally would.

ACTION	BMP	GIF	JPEG	PNG	TIFF
Post an image on a Web page		X	X
Export easily to other computer imaging programs	X				X
Compress a large image to create a small file to send in e-mail		X	X
Use transparent areas in images		X		X
Create animation files		X
Decompress images without loss of quality		X		X
Create highest quality images (for publishing, etc.)					X
Display millions of colors in an image	X		X	X	X
Retain image quality through numerous saves	X	X		X	X

 NOTE   The formats that are generally used for Web pages are GIF and JPEG. When you add a graphic other than a GIF or JPEG to a page and then save it, FrontPage automatically converts the graphic to a GIF if it has 8 bits of color or less, or to a JPEG if it has more than 8 bits of color.
