What is PNG?


PNG stands for Portable Network Graphics. Basically PNG is a file format. You must have heard about GIF which is commonly used in Web ad banners. In GIF there are different images presented in a particular order.  PNG was created to replace GIF.  GIF, owned by Unisys, is perhaps the first name that comes to mind when we talk about lossless image compression formats. Users are free to make and send GIF files but there are some licensing issues which prevent them to develop software that builds GIF images. This is the reason PNG was created in 1996.

PNG is better than GIF in a number of ways. For instance

  • In PNG the degree of transparency is controllable.

  • You can tune the image in terms of color brightness

  • You can save images using true color.

  • An image in PNG file is ten to thirty percent more compressed than in a GIF format.

There are tools available such as Java, Flash used for the same purpose as PNG but the best thing about PNG is that it is easy to use for common users.
