Image Formats
Select an image file format for photos, artwork or other documents that you want to save as images. 
BMP and TIFF are standard image file formats generally used if you want to do additional image 
processing, such as photo touch-up or color correction. 
Right-click on the BMP icon to access the GIF and PNG image formats. When you select either of these 
formats, the format panel will change the BMP icon to the selected image format icon.
BMP—The *.bmp (bitmap) format is generally used when you want to do additional image processing, 
such as photo touch-up or color correction, as very little image compression is used when creating the 
file. When scanning 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 
or server, as image compression can reduce the file size by approximately 95% when compared to a BMP 
file of the same image. Company logos and small pictures on a webpage are often GIF images. The GIF 
compression, and limited color range, can result in the medium and large images looking grainy or pixi-
lated. 
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 
same image. However, the PNG compression is different from GIF compression in that PNG images look 
better when scaled. Therefore, PNG is often 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 used for photo 
editing. When scanning in color, it produces a file of similar quality and size to a BMP file. However, when 
scanning in Black & White, the TIF compression produces the smallest file size of all the image types 
without losing image quality. TIFF also supports multi-page image files.
