JPG vs.Gif vs. PNG


Hi, I'm Alejandro. Today I'll talk about the difference between these exchangable image formats.
JPEG/JPG (Joint Photographic Experts Group), GIF (Graphics Interchange Format), PNG (Portable Network Graphic) are all portable image formats. The main caracteristics of these are quality and resolution.

Fist of all JPG is just a compressed format of a JPEG image. It is commonly used for high quality photographs or complex graphics because of its abundant amount of colors (more than 16 million). On the other hand this is not the most recomended format for line drawing, lettering or simple graphic making.

GIF is a mostly used as a web uploaded image format. It uses a very limited number of colors which are mostly pixeled (e.g. instead of seeing curved lines you will see colored pixels diagonally arranged). Summing all up this is a web format, quick upload, easily manged, and medium quality.

Finally, PNG images are ideal for webs. It was developed as an equivalent freeware for .GIF but it ended up being even better. It can be compressed easier quicker and more than .GIF images, and it has the opacity caracteristic which can make an image more or less transparent. The bad news is tha .PNG images can not be animated.
