PNG file (Portable Network Graphic) is about raster images. The PNG format contains a specific palette of colors used in the picture. Such a graphic format is often used on the World Wide Web when images are added to web pages. Thanks to the use of the Deflate compression algorithm, raster images of the PNG file extension are available for compression without losing its quality.
This file format was developed to replace the GIF format, because the latter required the availability of paid software during a long period of time. Among the owners of web resources, PNG images are known for their excellent characteristics against the background of such formats. PNG supports color depth up to 48 bits. The main difference of GIF is that such a graphic file is limited to only 8 bits (only 256 colors). Unlike GIF, PNG does not support animated effects.
You can open PNG file using any kind of image viewer. In Windows OS you can simply double-click the mouse to view PNG images. This image format is supported in any web browser. If the user needs to change the saved image in the PNG version, it is done by using image editing utilities, such as Adobe Photoshop or Microsoft Windows Photos, as well as Corel PaintShop or ACD Systems.
This file extension is very popular and carries all the necessary graphic information for full-color images of high quality.
