What is a PNG (Portable Network Graphics) file?

Portable Network Graphics (PNG) is a raster-based file type that compresses images for portability.

PNG also supports animations with better transparency (try our GIF to APNG). The benefits of using PNG are Plus, PNG is an open format that uses lossless compression.

How to open a PNG file?

Generally, PNG files will open in your operating system’s default image viewer. PNG files are also easily viewable on all web browsers. If you are having trouble opening PNG files, use our PNG to JPG, PNG to WebP, or PNG to BMP converters.

Alternative programs such as GIMP or Adobe Photoshop are useful for opening and editing PNG files. PNG files are a bit larger than other file types, so exercise caution when adding them to a web page. One interesting feature of PNG files is the ability to create transparency in the image, particularly a transparent background.
