These two formats are among the most widely used image formats on the internet, but they serve very different purposes. PNG is a lossless format offering full transparency, making it screenshots and design assets. JPG applies file compression to create significantly smaller files.
The most common motivation to transform PNG to JPG is storage. A single PNG photo is often several times bigger the equivalent JPG. For websites, resulting in into slower page load times and poor PageSpeed read more results.
Converting PNG to JPG is the correct option if you are handling photos without need a alpha channel. Also ideal if you need to decrease storage for faster sharing.
But PNG to JPG conversion is not necessarily appropriate. When the PNG image contains a clear canvas for example a icon, converting it to JPG fills that transparency with white background, destroying the alpha.
