What is a .png file?

File extension details and usage information

PNG (Portable Network Graphics) is a raster graphics file format that supports lossless data compression. It was created as an improved, non-patented replacement for GIF (Graphics Interchange Format), and is widely used on the internet and in image editing software. PNG excels at storing images with sharp lines and textual or iconic graphics, making it ideal for logos, diagrams, illustrations, and web graphics. It supports a wide range of color depths, including grayscale, indexed color, and truecolor (RGB) with optional alpha channel for transparency. The lossless compression ensures that image quality is preserved during saving and editing, unlike lossy formats like JPEG. PNG also supports interlacing, which allows a low-resolution version of the image to be displayed quickly while the full image is being downloaded. This makes it a good choice for web images where perceived loading speed is important. The format is well-supported across different operating systems and browsers, making it a universally accessible image format.

Can .png files be converted?

Options for saving or exporting this file to another format

  • Use the original software that created the file when possible.

Why can't I open a .png file?

Frequently Asked Questions

Common questions about .png files

To open a .png file, use software that supports this file format.

  • Adobe Photoshop
  • GIMP
  • IrfanView
  • Paint.NET
  • Microsoft Paint

Open the file in compatible software and look for options such as Save As, Export, or Convert. If no export option is available, the file may require a specialized converter or the original application that created it.

  1. Verify that the file extension is correct.
  2. Install or update compatible software.
  3. Try another application that supports this format.
  4. Check whether the file is corrupted, incomplete, or encrypted.

A file extension alone does not guarantee whether a file is safe or unsafe. Only open files from trusted sources, scan unknown files before opening them, and be especially careful with executable, script, archive, and document files.

File safety tips

Use caution with unknown files

Only open files from trusted sources. Before opening a .png file, scan it with antivirus software, verify that the file extension is expected, and avoid running unknown executable, installer, macro-enabled document, or script files.
