JPG and PNG are two of the most popular file formats on the web, however they have very different roles. PNG is a lossless file type with full alpha channel, making it screenshots and icons. JPG uses lossy compression to generate far smaller files.
The most common motivation to change PNG to JPG is storage. A single PNG image can be several times the size of the same JPG. For websites, resulting in directly to slower site performance and lower PageSpeed results.
Converting PNG to JPG is the correct decision whenever you're working with photographs without need a alpha channel. Also ideal if you need to decrease file size for improved web uploads.
Note that PNG to JPG conversion is not always the right choice. If your PNG file has a alpha channel like a graphic, converting it to JPG replaces that transparency with white background, removing the alpha.
