[PNG Files] What Is a PNG File? Everything You Should Know

PNG File Format

A raster image file format called a PNG (Portable Network Graphics) file employs lossless compression. This file format has no copyright restrictions and was developed to replace the Graphics Interchange Format (GIF). But, animations are not supported by the PNG file format. Unlike RAW format images, PNG files allow for lossless picture compression, so the format is well-liked by its users. PNG has become one of the most frequently used image file types over time.

The PNG format's primary features are listed below.

  • 🌐Web standard for image rendering: PNG is the format of choice for many websites.
  • 🎇Lossless: PNG has a lossless compression technology, which produces good image quality, in contrast to several other file formats, including JPG.
  • 🪟Enables transparency: PNG enables you to choose a translucent background necessary for graphic designers and illustrators. This allows erratic images, graphics, and logos to overlay a background color.
  • 🚫Animation is not supported: PNG images do not support looping animations, unlike the more antiquated GIF format (which is also lossless).

What Is a PNG File Used for

To display high-quality digital images, websites frequently use the PNG file format. PNGs, which were developed to outperform GIF files, provide lossless compression and a significantly wider and brighter color spectrum. Usually, PNG files are used for:

1. Translucent backgrounds for logos

For logos, designers frequently utilize PNG files. This allows designers to naturally layer logo files on various backgrounds since the format permits transparent backgrounds.

2. Graphs and charts for online

Since the PNG format employs lossless compression, all the original data in this file type is kept even after compression. Because none of the crucial details are lost, PNGs are excellent for comprehensive website graphics and charts.

How to Open PNG Files

Almost all editing software packages can open PNG files. You may access and view them without any issues using the Adobe suite. You might use these file types as a backup for your work. You can revise and tweak your work endlessly without sacrificing quality.

Both Photos and the native picture viewer for Windows or Mac will open this format using the operating system's default tools. You can use any internet browser if you don't have any editing software and would instead use something else. Furthermore useful, Google Drive gives you a preview.

Here are the basic methods to open the PNG files:

  • Double-click to open a PNG file in the default image viewing or editing program.
  • You can always open a PNG in Windows Picture Viewer by right-clicking the image and choosing Preview, even if you change the default software later.
  • Use the top menu for file operations, such as copying an image, printing, emailing, burning to a disc, or opening it in another program.

Open and Edit PNG

  • Click Select Default Program and select software to modify the default viewer or editor for PNG files. Any PNG can be double-clicked to launch the software of your choice rather than Windows Picture Viewer.
