Key Things to Know About the PNG File Format

PNG (Portable Network Graphics) is a file format used to compress digital images. It was initially developed as an improved and non- patented substitute for Graphics Interchange Format (GIF). Simply put, it is an alternative to GIF format that is patent-free and more flexible.

Nowadays, PNG is one of the most popular image formats on the internet, and it also acts as a better replacement for the JPEG images. And the best thing is that you can easily convert your PNG files into PDF format. If you have no idea how to go about it, you can go to https://www.viewpdf.com/png-to-pdf.html for guidance on that.

Here are some key things you need to know about the PNG file format.

Advantages of PNG

  • Lossless compression – this is the main advantage of PNG over any other format. You will not lose the details, data, or the quality of your compressed images even after a series of encoding and decoding.
  • Various color depth – if you have a variety of digital images, such as graphics and photographs, you don’t have to worry. PNG suits all your needs, whether the pictures are palette-based or grayscale images or full – color non- palette-based.
  • Transparency Support – Unlike JPEG, which exhibits transparent areas as a solid white color, PNG supports digital images’ compaction in transparent areas.
  • Perfect for image editing-it is ideal for storing your photos for editing due to its lossless compression feature. However, much encoding and decoding take place; your images will still be in excellent quality.

Disadvantages of PNG

While PNGs benefits are much more than GIF and JPEG formats, it comes with a few shortcomings:

  • Large file size – the major setback of PNG is compressing digital images into a bigger file size, unlike the JPEG format that uses a smaller size for the same image resolution and quality.
  • It does not allow printing – Ideally, this format was designed purposely to distribute digital images online. Therefore, you can’t enjoy the privilege of a hardcopy since it does not support non – RGB color spaces.
  • It does not support animation – besides EXIF metadata non – embedment, PNG format does not also support animation despite the availability of unofficial extensions.

Uses of PNG

a logoBesides creating logos, you can also use PNG to create web page navigation elements, lithographs, graphs, text engravings and images with sharp corners. This is because of its ability to take pictures in a transparent background and compress images while maintaining quality and coherent boundaries.
