PNG files are used to store bitmap images. This format was developed as an alternative to GIF files but without patents burden and with additional features like transparent backgroud. Files with the PNG file extension use indexed colors and lossless compression. PNG files cannot be animated like GIF images.
Opening a PNG file, or any other file on your PC, is as simple as double clicking on it. Most operating systems, both desktop, servers or mobile OS, have native software to open PNG files. If file extension associations are configured correctly, the base application to open PNG files will launch automatically when you double click on a PNG file.
It is also feasible to operate and modify PNG files through the use of graphic design software, such as Adobe Illustrator (https://www.adobe.com/). If for some reason, the PNG extension is associated with some other application, native to the operating system or not, it is necessary to open it from the Illustrator file menu or any other design program.
In the case of Illustrator, you can display the list of supported extensions and you will find the PNG extension, so only the images with PNG extension will appear in the file window.
It is necessary to make a special mention that most operating systems, whether Windows, based on Linux or MacOS, are preconfigured so that when making a screenshot with the preset key combination, the generated image is a PNG extension file.
PNG files are usually a bit greater than their JPG equivalent; This is because PNG files offer lossless image compression while JPEG compression is lossy. This difference can be observed in the image quality.
PNG images offer a good alternative to the GIF format, as they include an 8-bit transparency channel, support 24-bit RGB color palettes, RGB images and grayscale. Files with the PNG extension were introduced to simplify the transfer of images over the internet, but not to store professional graphics.
A special note, applying CMYK is not possible in PNG files.
