## The Advantages of PNG for Professional Graphics Converting JPG to PNG is a common step for developers and designers who need a 'clean' starting point for further work. While you can't restore data already lost by JPG compression, converting to PNG stops any future loss from occurring. This is known as preventing 'generation loss', which happens every time you save a JPG file. ### Transparency and Overlays The primary reason most people convert JPG to PNG is to work with transparency. Using specialized editing software, you can remove the background of a PNG image, making it perfect for website overlays, logos, and digital collages. Our tool prepares the file for this process perfectly. ## Why MyOnlyConverter is the Best Choice Unlike other tools that might compress your files further, MyOnlyConverter respects the original data of your images.
