Why do we convert PNG to JPG?

The relationship between the size of the file and internet speed is continuously becoming important for the user. Advancement in image technology enables us to make high-resolution images. High resolution means high-quality images. These high-quality images formats contain much information in the file and this results in not only large size of the file but also transfer and loading times are also increased.  You can solve this issue with the help of data compression.

Data compression is the process to reduce the file size. This process involves re-encoding the data to use fewer bits of storage in comparison with original data. The major advantage of data compression is that the original file can be transferred or stored. It can also be recreated and used later. This process is called decompression. The real benefit of data compression was realized when the Lossless compression algorithm came in to scene. Date compression is divided into two major types which are explained in the following lines.

Lossy compression: This is a type of compression in which some of the unnecessary information is lost making the file size smaller. This type of compression is used in videos and audios files.

Lossless compression: This is a type of data compression in which the size of the file is reduced without losing any bit of information. But this process reduces the redundancies within the data resulting in a decrease in file size. In this type of compression, the original file is reconstructed perfectly. An example of this type of compression is ZIP which is being used in windows.

To convert PNG to JPG, it is necessary to know what are PNG and JPG files.

JPG Files

JPG file format is designed to reduce the file size of photographs and make them more suitable for sharing on the website or over email. The original format of the image is called raw image. When the raw image is converted into the JPG format then some of the quality of the image is lost because some of the information is permanently deleted lost. This is due to the fact JPG format uses lossy compression.

PNG files

PNG is the type of file format which uses lossless compression. This means the image size is reduced without compromising the quality of the image.  The high resolution of the image is maintained throughout the compression process. Whenever this image is unpacked and reverted to its original size, no change in the quality of the image is seen. That is why PNG file formats are preferred in product photography.

Besides, the advantage and disadvantage of PNG and JPG file formats, conversion of PNG to JPG become necessary for the user depending upon the type of usage especially when the internet speed is poor or images need to be loaded again and again like on website.

Operating systems like Windows and MAC help to convert PNG to JPG by built-in features along with a guide on how to convert. Now browser-based system like Google is also available. There are also online conversion sites available that are making PNG to JPG conversions easier and offering more tools free of cost.
