PNG Full Form

PNG Full Form– Portable Network Graphics (PNG) is a raster graphics file format used for storing images on the Internet. It was developed in the mid-1990s as an alternative to the GIF format, which at the time was the dominant format for storing images on the web.

One of the main advantages of PNG over GIF is that it supports full-color images (24-bit) with alpha transparency, which allows for seamless blending of images with backgrounds. PNG also supports lossless compression, which means image quality is not compromised when the file size is reduced.

PNG is widely used for storing images on the web, especially for graphics that require transparent backgrounds or high-quality images with lots of detail. It is commonly used for storing images in applications, such as image editing software and for saving screenshots.

PNG files are usually identified by the .png file extension.

History of Portable Network Graphics (PNG)

The Portable Network Graphics (PNG) format is a lossless image compression format developed in the mid-1990s as an alternative to the GIF format, which was proprietary and had patent licensing issues. The development of the PNG format was led by an Internet group called the PNG Development Group, which included members from various software and hardware companies, including CompuServe, Apple, and Microsoft.

The main goal of the PNG format was to create a universal image format that could be used on the World Wide Web and other online platforms, and which could be freely used without any licensing restrictions. To achieve this goal, the PNG format was created to be completely lossless, meaning it can reproduce an image with 100% accuracy without losing any quality.

The PNG format was also designed to be highly efficient, allowing the creation of smaller file sizes while maintaining high image quality. This made it particularly useful for the transfer of images over the Internet, where bandwidth was often limited.

The PNG format was first released in 1996, and quickly gained widespread adoption due to its many advantages over other image formats. It is now the most widely used image format on the Internet and is supported by most web browsers and image editing software.

Evolution of Portable Network Graphics (PNG)

Portable Network Graphics (PNG) is a raster graphics file format that uses lossless data compression. It was developed in the mid-1990s as an open source alternative to GIF, which was under CompuServe’s patent at the time. PNG was designed to be able to transfer images over the Internet, particularly in web applications, and to be compatible with existing web browsers and platforms.

The development of PNG was led by an Internet group called the Portable Network Graphics Group, which included representatives from various organizations including CompuServe and the World Wide Web Consortium (W3C). The group was founded in 1995 to develop a new image format that would be able to replace GIF, but without the legal restrictions of patents.

PNG was designed to be a simple and efficient format that can be used for a wide range of applications. It supports 24-bit color, as well as grayscale and indexed color images. It also supports transparency, allowing images to blend onto other images or backgrounds with smooth anti-aliased edges.

PNG was first released in 1996, and has since become a popular choice for storing and transmitting images over the Internet. It is widely supported by web browsers and image editing software, and is often used for saving images for the web, as well as for storing graphics for applications and games.

What is the file format of Portable Network Graphics (PNG)

Portable Network Graphics (PNG) is a bitmap image format that uses lossless data compression to store raster graphics. It was designed to replace the GIF format, which was previously widely used for storing images on the web.

PNG is a binary file format, which means that it consists of a series of bits (0s and 1s) that represent image data and other information about the image, such as size, color depth, and transparency. It stores images in a compressed form, which means that the file size of a PNG image is usually smaller than the file size of an uncompressed image in a format such as BMP or TIFF.

PNG images are organized into a series of “chunks”, each of which contains a specific piece of information about the image. Some types of parts that can be included in a PNG file are:

• IHDR: This chunk contains information about the size, color depth, and color type of the image.
• PLTE: This chunk contains the palette table, which specifies the colors used in the image.
• IDAT: This chunk contains the actual image data, which is compressed using a lossless compression algorithm called deflate.
• Text: This section contains text metadata about the image, such as the image title, author, or copyright information.
• Gamma: This chunk contains information about the gamma value of the image, which is used to correct for differences in display devices.

PNG files are identified by their file extension, which is “.png”. They can be opened and edited using a variety of image editing software, such as Adobe Photoshop, GIMP, or PaintShop Pro.

Advantages of Portable Network Graphics (PNG)

There are several advantages to using the Portable Network Graphics (PNG) format for image files:

• Lossless Compression: PNG format uses lossless compression, which means it can reproduce the image with 100% accuracy without losing any quality. This makes it ideal for storing images that require a high level of detail, such as photographs and graphics with text.
• Small File Size: The PNG format is highly efficient, allowing the creation of small file sizes while maintaining high image quality. This makes it particularly useful for the transfer of images over the Internet, where bandwidth may be limited.
• Wide Support: The PNG format is widely supported by web browsers and image editing software, making it easy to view and edit PNG images.
• Transparency Support: The PNG format supports transparency, meaning that pixels in an image can be set to be transparent, allowing the image to be displayed over other images or backgrounds without solid color blocks.
• No Patent Restrictions: Unlike the GIF format, the PNG format has no patent restrictions, making it free to use without a license.
• High-Quality Printing: The lossless nature of the PNG format makes it suitable for printing high-quality images, as it ensures that the printed image will be of the same quality as the original.

Difference Between PNG and JPEG

PNG (Portable Network Graphics) and JPEG (Joint Photographic Experts Group) are both popular image formats used for storing and sharing digital images. However, they have some key differences that make them suitable for a wide variety of images and uses.

The main difference between PNG and JPEG is how they handle image data. PNG is a lossless format, which means that it does not lose any image quality when the image is saved and compressed. This makes it a good choice for storing images that need to be edited or modified, as well as for images that require a high level of detail and clarity, such as logos or graphics.

On the other hand, JPEG is a lossy format, meaning that it sacrifices some image quality in order to achieve smaller file sizes. This makes it a good choice for storing photographs and other images that do not require a high level of detail, and where a small file size is more important than preserving all the original image data.

Another difference between the two formats is their support for transparency. PNG supports transparency, which means that it is possible to make parts of an image transparent so that the background is visible. This makes it a good choice for storing images that need to be superimposed on top of other images or backgrounds. JPEG does not support transparency, so it is not a good choice for images that require this feature.

In short, PNG is a lossless format that is good for storing images that require a high degree of detail and transparency, whereas JPEG is a lossy format that is better suited for storing photographs and other images. . , , , where smaller file sizes are more important than preserving them all. original image data.

Which software supports Portable Network Graphics (PNG)

Most software programs designed for editing and viewing images support the Portable Network Graphics (PNG) format. This includes both professional image editing software and more basic image viewing programs. Some examples of software that supports PNG include:

• Adobe Photoshop: A professional image editing program widely used by photographers, graphic designers, and other creative professionals.
• GIMP: A free and open-source image editing program that is similar to Photoshop in terms of features and capabilities.
• PaintShop Pro: A professional image editing program popular among photographers and other professionals.
• IrfanView: A lightweight image viewing and editing program available for Windows.
• Preview: The built-in image viewing and editing program for macOS.
• Microsoft Paint: A basic image editing program included with the Windows operating system.
• Google Photos: An online photo storage and organization service that allows users to view and edit their images, including PNG files.

In addition to these specific programs, many other image editing and viewing software supports PNG, including proprietary and open-source programs.

File size of Portable Network Graphics (PNG)

The Portable Network Graphics (PNG) file size can vary greatly depending on the content of the image and the settings used to save it. In general, PNG files are larger than other image file formats, such as JPEG or GIF, because they use lossless compression, which means that no data is lost when the image is saved. This can result in higher quality images, but also larger file sizes.

Some factors that affect the size of a PNG file are:

• Image Dimensions: Larger images will generally result in a larger file size, regardless of file format.
• Image complexity: Images with more detail or more colors will result in a larger file size.
• Compression level: PNG files can be saved with different levels of compression, with higher levels resulting in smaller file sizes but potentially lower image quality.
• Transparency: PNG files support transparency, which can increase the file size if the image has a lot of transparent areas.

In general, you can expect a PNG file to be larger than an equivalent JPEG file due to the lossless compression used by PNG. However, the exact size of a PNG file will depend on the specific content of the image and the settings used to save it.
