Vector art files are mathematical design assets that produce crisp, high-resolution output at any rendered size. They are idea for large format output compared to standard web and pixel images that are made up of tiny, colored squares.

Vectors can be saved in several common file formats. SVG and PDF are the most widely accessible. EPS is another common file type that is a legacy standard for print. File formats for design programs include AI (Adobe Illustrator) and AFDESIGN (Affinity Design). Vectors can also be embedded and exported from layered design files used by programs use as Adobe Photoshop (PSD).

For projects that need a clean image at any size you need a correctly made vector art file. Most files downloaded from the web for use with a Cricut, Silhouette, or Glowforge cutter or engraver will have fuzzy lines and edges the rendering process will try to interpret all the tiny pixel squares as solid lines. Vector artwork is also required for embroidery and large-scale vinyl plotters.
