These two formats are among the most widely used file formats on the web, however they have very distinct purposes. PNG is a lossless format offering full clear backgrounds, perfect for graphics and icons. JPG uses lossy compression to produce much smaller file sizes.
The most common reason to convert PNG to JPG is image size. Each PNG image can be five to ten times larger the comparable JPG. For online use, this means directly to slower page load times and poor PageSpeed results.
Converting PNG to JPG is the correct option if you are handling photographs without require a transparent background. It is also perfect when you need to decrease storage for faster sharing.
Note that PNG to JPG conversion is not the right choice. If your PNG file has a alpha channel like a logo, changing it to JPG fills the transparent area with a solid color, destroying the alpha.
