When you select either of these formats, theformat panel will change the BMP icon to the selected image format icon.Right-click on the JPG icon to access the JP2 image format. When you select JP2, the format panel will change theJPG icon to the JP2 format icon.BMP—the *.bmp (bitmap) format is generally used when you want to do additional image processing, suchas photo touch-up or color correction, as very little image compression is used when creating the file. Whenscanning in color or grayscale, BMP scans result in the largest file size of the image formats.GIF—the *.gif (graphics interchange format) format is generally used when putting images on a website orserver, as image compression can reduce the file size by approximately 95% when compared to a BMP fileof the same image. Company logos and small pictures on a webpage are often GIF images. The GIFcompression, and limited color 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 for website graphics.Like GIF, the PNG compression greatly reduces the file size when compared to a BMP file of the sameimage. However, the PNG compression is different from GIF compression in that PNG images look betterwhen scaled. Therefore, PNG is often used in place of GIF for company logos with a lot of detail, clickablebuttons, medium sized pictures, and so on.TIFF—the *.tif (tagged image file format) format is another image type that is often used for photoediting. When scanning in color, it produces a file of similar quality and size to a BMP file. However, whenscanning in Black & White, the TIF compression produces the smallest file size of all the image typeswithout losing image quality. TIFF also supports multi-page image files.JPG—the *.jpg (joint photographic experts group) format is a common image format for transferringpictures electronically, such as posting to a website or sending via email, as JPG image files are smaller thanBMP and TIFF files. You can change the level of compression for the picture file to have better quality or asmaller file size.JP2—the *.jpg2 (joint photographic experts group 2000) format is the new JPEG standard. This new JPG filetype has improved compression for better image quality at smaller file sizes. Please refer to the official JPEGwebsite at www.jpeg.org for more information about this file format, and a list of applications that can viewand/or open this file type.
