Have you ever received an email that contains an attached PNG file? Or maybe you’ve seen the PNG format when saving a project on your computer or device? Whatever the reason for asking what a PNG file is, this simple guide will reveal all.

What Is a PNG File?

A PNG (Portable Network Graphic) is an image file format that contains a bitmap and uses lossless compression - similar to a .gif file, but without the animation. Its 24-bit RGB and 32-bit RGBA indexing make it a popular choice for web graphics and digital images.

PNG pictures are versatile, and you can open, save, and edit them on most operating systems. In fact, macOS computers save screenshots as PNG images by default, while photo applications on Windows devices will open as PNG files. 

You can use this image file type with browsers, photo editing software like Photoshop, and various other applications. The .png file can additionally be uploaded to your website builder or attached to emails like other image files.

PNGs are a type of raster image file. While not as common as JPG images, the PNG file format is recognizable by most computer users. It is an excellent choice for small images that require original quality and don’t impede website loading times. PNG images can be viewed, edited, saved, and shared like any other image file type.  

Now that you can answer the questions, what is a PNG file and what is a PNG file used for, let's get more technical.

How to Open a PNG File?

You can open PNG photos in any popular web browser, including Firefox or Chrome. As such, you can view these images without having to save them to your hard drive or an external storage solution.

If using Windows, you can open a PNG photo in your preferred web browser with the simple key-strokes - Ctrl + O.  

To open a PNG in Photoshop, Google Drive, or other applications, try this: File -> Open -> Select your file -> Enter. Keyboard shortcuts may also be helpful, including the “+” sign when working in Google Drive.  

PNG file opening is far from a hassle and similar to many others.

How to Convert a PNG File?

A PNG file is convertible to meet users’ needs. For example, you may want to make the file smaller and modify it into a JPG. No problem, as conversion to this file format is possible and, better yet, simple to accomplish. Most operating systems and their related image software can make these file type changes, including Photoshop and Corel Draw. Intuitively go to File -> Save As -> Choose new file type from a dropdown menu.  

Done and done!

You can also export PNG photos as other file types on Paint, Apple Preview, and a range of other photo viewer packages.
