When creating a logo, it's often said that it should be made using vector images. Vector images aren't made up of pixels (small dots); instead, they are defined by the directions of lines and curves.
You’ve probably heard the term “resolution.” If an image is made up of many pixels, it’s said to have a high resolution. However, no matter how high the resolution of an image is, if you zoom in on a part of it, you’ll notice that the pixels start to appear jagged.
his can happen even with a logo image that looks clean when not zoomed in.
However, with vector images (SVG), you won’t see this pixelation no matter how much you zoom in because the image is defined by direction rather than pixels.
Common vector image formats include SVG (Scalable Vector Graphics), AI (Adobe Illustrator), and sometimes EPS, although it’s not as widely used. For bitmap images, formats like PNG, JPG, and TIFF are common.
Be cautious with PDFs. While PDF is fundamentally a vector format, it can contain bitmap images. Therefore, you shouldn’t assume that a PDF is always a vector image. For example, if you import a bitmap image into PowerPoint and then export it as a PDF, the resulting PDF will contain a bitmap image.
