• Stands for Joint Photographic Experts Group.• It is mainly used for photographs and also a wide range
of colours. It can achieve high compression ratios even whilst maintaining high image quality. GIF compression is unkind to such images. JPG works by analyzing images and discarding kinds of information that the eye is least likely to notice. It stores information as 24 bit color. Important: the degree of compression of JPG is adjustable.
• A disadvantage is that JPEG doesn’t work very well with simpler images those with not much detail or colour
JPEG
BMP• BMP is an uncompressed format invented by
Microsoft. There is really no reason to ever use this format but here some information on it.
• BMP File Format or simply a Bitmap.• Does not support compression • DON’T USE ON MACS!
GIF• GIF stands for Graphic Interchange format• Gif is file format manly used recurring moving
images or animation, the two images at the top are examples of GIFS
• The format only support 8 bits per pixel and also only has 256 colour palette which means some colours might not show.
• GIF is highly supported by the internet
TIF• Tif stands for Tagged image file • It is a raster file so it saves its images in pixels
this has its ups and downs because with this the image is much smoother and sharp but it also makes the file huge.
• Web browsers also do not support this file but scanners work best with them
PNG• PNG stands for portable network graphics.• Similar to TIFF because it is a raster file so the
same problem occurs with the file being very big.• It also is a platform independent format which
means you don’t need a certain program to use it which is a big advantage
• This file is supported by more recent web browsers but may cause troubles with old web browsers
