Why Convert JPG to PNG?
JPG (JPEG) is a lossy image format designed for photographs that discards minor visual data to reduce size. In contrast, PNG (Portable Network Graphics) uses lossless compression, meaning the image quality does not degrade upon re-saving.
Converting JPG to PNG is an essential step when preparing images for graphic editing software, overlaying assets, or using pictures where crisp edges and sharp text clarity are paramount.
