| Description | JPG is a lossy compressed image format widely used for photos on the web, social media, and cameras. It balances acceptable visual quality with small file sizes, but repeated saving can gradually introduce compression artifacts and reduce fine detail. | PNG is a lossless raster image format that preserves exact pixel data and supports transparency. It is ideal for logos, icons, UI elements, and graphics with text or sharp edges where clarity, alpha channels, and clean backgrounds matter more than minimal file size. |
