Different file formats?

Question

What does GIF/PNG/JPG file format mean?

Answer 1

A GIF file is an image file which allows only a relatively small number of colours (compared with the others you mentioned), but has the advantages of having small a small file size, supporting animated images and utilising transparency (effective for web pages)



A PNG file can be seen as a more advanced version of a GIF file - it supports more colours and handles transparency better. For this reason it is very potent on web pages - giving them aesthetic appeal because of the smooth transparency.



A JPG file does not handle transparency at all, but is supported by the vast majority of image editing programs and is used my most consumer cameras (even SLRs but they often allow .RAW files as well). It also allows a good balance between quality and file size.



Hope this helps! :)
