The document discusses different image file formats: JPG, BMP, GIF, TIFF, and PNG. It provides brief descriptions of each format, including what they are used for, their key features like supported color depth and compression ratios, and considerations around browser support and file sizes. JPG is best for photographs with many colors. GIF is mainly used for animations and supports 256 colors. TIFF produces sharp images but results in large file sizes. PNG is platform independent but may not be fully supported on older browsers.

1. Here Are Some Formats You May Or May Not Know
But Will Be Discussed In This Help-sheet.

2. • 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.

3. • BMP is an uncompressed proprietary format
invented by Microsoft. There is really no
reason to ever use this format but here some
information on it.
• BMP File Format, also known as Bitmap Image
File or Device Independent Bitmap (DIB) file
format or simply a Bitmap.
• DON’T USE ON MACS!

4. • 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

5. • Tif stands for Tagged image file
• It is a raster file so it saves its images in pixels
this has it up 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
scanner work best with them

6. • 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
