Vector icons are graphic design elements that are created using vector-based software, such as Adobe Illustrator or Sketch. Unlike raster images, which are made up of pixels, vector icons are created using mathematical equations, which means that they can be scaled to any size without losing quality or becoming pixelated. This makes vector icons highly versatile and suitable for a wide range of design applications. Vector icons can be used in various digital and print media, such as websites, mobile applications, social media graphics, brochures, posters, and more. They are typically available in various file formats, such as AI, SVG, EPS, and PDF, and can be easily edited and customized using vector-based software.
