Introduction to PNG File Format

Basic features of PNG

PNG stands for Portable Network Graphics, which was introduced in 1995. PNG is an image format used as a replacement for .GIF, ensuring image quality. PNG is capable of lossless image compression at both 8-bit and 24-bit, providing stability and high quality.

What’s important is that PNG uses compression technology without loss of image information, preserving detail and color. PNG also stands out with its ability to display transparent images, making it a popular choice for creating images with transparent backgrounds.

Especially, PNG is often referred to as a format without a background, making it easy to integrate images into graphic projects and edit images. It is not only a file format, but also a powerful tool that supports creativity in expressing ideas and creating unique digital artworks.

Applications of the PNG format

The PNG format has endless possibilities and is used for:

  • Creative design with PNG: A powerful tool for creative people, helping them save time by eliminating the step of removing the background for each image.
  • PNG format on websites: PNG is an ideal choice for creating sharp images with vivid and compatible effects on web pages, providing an excellent experience for users.
  • Maintaining high image quality: Lightweight when uncompressed and at the same time maintaining high image quality.

PNG is the perfect choice for creating high-quality images in any situation, with diverse and useful applications.

Components of a PNG image

So what are the main components of a PNG image? To process and display PNG images, a Decoder decoding set is needed, which includes the following 4 components:

  • IHDR Chunk (Header): is the first part containing the internal headers
  • PLTE Chunk (Color Table): Contains the color table to be used in the image, providing accuracy and variety in displaying colors.
  • IDAT Chunk (Image data): This section contains image data, which can include one or more IDAT “chunks” to hold image information. This is the reason why the PNG image file size is large.
  • IEND Chunk (End): Marks the end point of the PNG image, ensuring the completeness of the file.

These components combine to create a complete and high-quality PNG image.

Advantages and disadvantages of the PNG file extension

Advantages

  • Store high-quality images

PNG uses reference libraries to reproduce images, ensuring high quality and sharpness. This feature helps PNG preserve the detail and accurate color of the image that is rarely compressed or even not compressed. This makes PNG an excellent choice for storing high-quality images with high quality requirements, especially when it is necessary to preserve the details in digital artworks and photo editing.

At the same time, PNG not only preserves high image quality but also supports transparency from 0 to 100%, ensuring flexibility when integrated into different platforms.

  • Easy to use for users

PNG is popular because of its high compatibility, making it smooth on many devices, websites, and applications. The easy editing feature of PNG allows users to cut, splice, and modify images more conveniently and comfortably, so users can unleash their creativity without limitations.

Disadvantages

Here are some of the disadvantages of the PNG format that users often consider when using it for image editing:

  • Large file size: PNG has a large file size due to its focus on high image quality.
  • Black background issue: On some browsers, PNG images do not display correctly when the background color matches the transparency color of the image, as the application replaces it with a black/white background color.
  • Older browsers: Older browsers may not support proper PNG display or have quality issues.
  • Requires specialized software: PNG can only be created through professional applications and software, not from ordinary devices.

Although these issues are not too serious, they can create significant difficulties for users.

Commonly asked questions about PNG

Today, users still commonly ask the question What is PNG? Here is some new information about this format that you may not know.

How does PNG image compression technology work?

The image compression technology of the PNG format is based on the libpng reference library and independent C functions, opening up significant advances in image compression processing.

Although PNG is often known as an image format with a transparent background, in reality, only a few PNG images actually have a transparent background. This technology not only keeps the image quality but also marks the innovation in image compression.

The difference between PNG 8-bit and PNG 24-bit

PNG 8-bit and PNG 24-bit are two popular PNG image formats, each with its own advantages and disadvantages.

  • PNG 8-bit uses 256 colors, suitable for simple graphics, small file size, and fewer colors. PNG 8-bit images are compatible on all platforms, but the disadvantage is that they have a fairly high level of transparency.
  • PNG 24-bit uses millions of colors, making it suitable for images with complex colors, such as photos, artworks, logos, etc. PNG 24-bit has high transparency, making it suitable for creating images with a transparent background and having a relatively large file size.

In what cases is the PNG format commonly used?

The PNG format is commonly used in the following cases:

  • Supports transparency: Especially in the PNG-24 version, it helps display images, charts, and icons on web pages without a background, creating an aesthetic and professional feeling.
  • An uncompressed image format: PNG is suitable for images with many colors and details, especially when it is necessary to preserve the high quality of the image.
  • PNG does not lose image quality when saved multiple times: This makes it a good choice for editing and storing images without quality degradation over time.

In summary, PNG is a versatile and diverse format, suitable for many applications, especially in web design, complex graphics, and processes working with images that require flexibility and high sharpness.

Does PNG support animation?

Ordinary PNG does not support animation, but there is an extended version called APNG (Animated Portable Network Graphics) used to support animated images, while still preserving PNG’s features. You need to check the compatibility of the browser or software before using this tool.
