What is a PNG file?
PNG stands for Portable Network Graphics. It’s a popular raster image format developed as an open alternative to GIF. Released in 1996, PNG supports lossless compression, which means the image quality is preserved when the file is saved.
PNG is ideal for graphics that need transparency, sharp edges, or repeated editing — such as logos, icons, and screenshots. Unlike JPG, it retains full detail but usually results in larger file sizes.
How to open PNG files
PNG files are supported by nearly all operating systems and applications. You can open them using default image viewers on Windows, macOS, Linux, Android, and iOS.
Web browsers, design software like Adobe Photoshop, and online tools such as AnyConv also handle PNG files without issues.
