JPG vs PNG JPG compresses photographs by discarding detail; PNG preserves every pixel and supports transparency. PNG vs WebP PNG is the lossless workhorse for graphics and transparency; WebP delivers similar quality in dramatically smaller files. JPEG vs JPG JPEG and JPG refer to the same image format, the shorter name is a leftover from old three-letter filename limits. WebP vs AVIF WebP is the widely supported modern format; AVIF pushes compression further at the cost of encode time and edge-case compatibility. PDF vs Word PDF locks a document's exact appearance across every device; Word keeps it editable and reflowable. What Is Transparency in Digital Images Transparency lets pixels reveal whatever sits behind them instead of showing a solid color. Lossy vs Lossless Compression Two philosophies of shrinking files, one throws away detail you likely won't miss, the other preserves every bit.
