What is JPG to PNG conversion?

JPG to PNG conversion changes a JPEG (Joint Photographic Experts Group) image into Portable Network Graphics. JPG (or JPEG) is a lossy raster image format built for photographs. It compresses images by discarding image data that's hard for the human eye to notice, producing small files at the cost of some quality on repeated saves. PNG is a lossless raster format designed for the web. It preserves every pixel exactly and supports full alpha-channel transparency, making it the standard choice for graphics, logos, and screenshots. Converting between the two lets you pick whichever format best fits where the image is headed next.

Why convert JPG to PNG?
