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 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 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.

JPG—the *.jpg (joint photographic experts group) format is a common image format for transferring
pictures electronically, such as posting to a website or sending via email, as JPG image files are smaller than
BMP and TIFF files. You can change the level of compression for the picture file to have better quality or a
smaller file size.
JP2—the *.jpg2 (joint photographic experts group 2000) format is the new JPEG standard. This new JPG file
type has improved compression for better image quality at smaller file sizes. Please refer to the official JPEG
