When you select either of these formats, theformat panel will change the BMP icon to the selected image format icon.To select a JPEG file size:1. Select JPG as the page format.2. Right-click on the JPG icon.A menu opens.BMP—the *.bmp (bitmap) format is generally used when you want to do additionalimage processing, such as photo touch-up or color correction, as very little imagecompression is used when creating the file. When scanning in color or grayscale, BMPscans result in the largest file size of the image formats.GIF—the *.gif (graphics interchange format) format is generally used when puttingimages on a website or server, as image compression can reduce the file size byapproximately 95% when compared to a BMP file of the same image. Company logosand small pictures on a webpage are often GIF images. The GIF compression, and limitedcolor range, can result in the medium and large images looking grainy or pixilated.PNG—the *.png (portable network graphics) format is another common image format forwebsite graphics. Like GIF, the PNG compression greatly reduces the file size whencompared to a BMP file of the same image. However, the PNG compression is differentfrom GIF compression in that PNG images look better when scaled. Therefore, PNG isoften used in place of GIF for company logos with a lot of detail, clickable buttons,medium sized pictures, and so on.TIFF—the *.tif (tagged image file format) format is another image type that is often usedfor photo editing. When scanning in color, it produces a file of similar quality and size to aBMP file. However, when scanning in Black & White, the TIF compression produces thesmallest file size of all the image types without losing image quality. TIFF also supportsmulti-page image files.JPG—the *.jpg (joint photographic experts group) format is a common image format fortransferring pictures electronically, such as posting to a website or sending via email, asJPG image files are smaller than BMP and TIFF files. You can change the level ofcompression for the picture file to have better quality or a smaller file size.
