Converting a JPEG image to a vector format involves a process called vectorization, where the raster image (made up of pixels) is transformed into a scalable format defined by paths and points. This is often done using software like Adobe Illustrator or online tools that utilize algorithms to trace the outlines of the image. The result is a vector file, such as SVG or EPS, which can be resized without losing quality, making it ideal for applications like logos, graphics, and custom embroidery designs. This conversion is especially useful for preserving the clarity of designs when scaling them for various uses.
