A raster image format stores images as a grid of pixels, where each pixel contains colour information. JPEG, GIF, and PNG are all popular file formats that store images using this pixel-based approach. SVG (Scalable Vector Graphics), on the other hand, is a vector image format. Vector images are composed of mathematical descriptions of geometric shapes, lines, and curves, making them scalable without loss of quality.
Raster images are pixel-based, while vector images are based on mathematical descriptions. SVG is a vector format.
Common raster formats include BMP, TIFF, and WebP in addition to JPEG, GIF, and PNG. Vector formats are often used for logos, illustrations, and graphics that need to be resized frequently because they scale smoothly without pixelation.
