Converting a JPEG to a vector involves transforming a pixel-based image into a scalable, resolution-independent graphic. This process uses software like Adobe Illustrator or Inkscape to trace the image and create vector paths, which can be edited and resized without losing quality. Ideal for logos, apparel designs, and large-scale prints, vector formats (such as SVG, AI, or EPS) ensure sharpness and clarity at any size, making them essential for professional design and printing applications.
