Bitmap image formats for the web—GIF, JPEG, WBMP, and PNG—describe images using a grid of pixels. The resulting files tend to be bulky, limited to a single (often low) resolution, and consume large amounts of bandwidth on the web. SVG, on the other hand, is a vector format that describes images as shapes, paths, text, and filter effects. The resulting files are compact and provide high-quality graphics on the web, in print, and even on resource-constrained, handheld devices. Users can magnify their view of an SVG image on‑screen without sacrificing sharpness, detail, or clarity. In addition, SVG provides superior support for text and colors, which ensures that users will see images as they appear on your Illustrator artboard.
You can save artwork in SVG format using the Save, Save As, Save A Copy, or Save For Web & Devices command. To access the complete set of SVG export options, use the Save, Save As, or Save A Copy command. The Save For Web & Devices command provides a subset of SVG export options which are applicable to web-oriented work.
