What is PNG file?

File with PNG extension contains raster graphics compressed using lossless compression method called deflate’ that supports alfa’ channel and 48-bit color. PNG files can store transparent pixels and 16-bit color per each channel. Each PNG file contains a single image. PNG doesn’t support animations - APNG and MNG formats are used for storing this type of data. PNG file header holds information abouts file type saved in ASCII text. PNG files can store:

  • RGB graphics,
  • RGBA,
  • ICC and ICM color profiles,
  • EXIF data.

PNG format was developed in 1995 as an alternative to GIF and is recommended by W3C consortium as the standard format for distributing images over the internet. RFC 2083 document, which specifies PNG format, was published in 1997, while ISO/IEC PNG standard specification was released in 2004. PNG files are also used for sharing and sending images or photos for print, although are not used for professional applications as PNG doesn’t support any other color models beside RGB (such as CMYK). Each PNG file consists of many part called ‘chunks’, which store information on given part of the image. PNG files can be compressed and filtered. PNG image files are supported by most web broswers and image editing and managing programs.

We hope we helped you solve the problem with the PNG file. If you do not know where you can download the application from our list, click on the link (which is the name of the program) - you will find more information there on the location where to download the secure setup version of the required application.

What else may cause problems?

There can be more reasons which determine that you are not able to open the PNG file (apart from the lack of the proper application installed).

First - the PNG file may be incorrectly associated with the application installed to support it. In this case, you need to change this association by yourself. To do this, right-click on the PNG file that you want to edit, click "Open with" and then select the program from the list that you have installed. After this operation, the problems with opening the PNG file should be solved.

Second - the file you want to open can simply be damaged. Then, the best solution is to find a new version of given file, or download it again from the same source as before (maybe for some reason in the previous session the download of the PNG file has not been completed and it cannot be opened properly).
