Lacking any existing third-party standard for vector graphics, the World Wide Web Consortium (WC3)'s SVG Working Group created the Scalable Vector Graphics (SVG) recommendation in 2001 for use on the web.
Some apps such as Sketch can import/export SVG, as well as a host of other files and formats including CSS (web), bitmaps such as PNG, JPG, GIF, TIFF and WebP, Figma files (.fig), PDF, Adobe Illustrator and Photoshop files, and even raw SVG code.
Even without compression, SVG files are usually tiny - many SVG files used on the web will be under 10KB in size and many more under 5KB.
For sites that allow image downloads, SVG allows graphics files to be easily exchanged on the web via web pages without additional servers or conversions.
macOS supports SVG, and there are many quality apps that can edit, export, import, and save SVG graphics as image files.
