Converting a JPEG to vector format involves transforming a raster image (made up of pixels) into a scalable vector graphic (composed of mathematical paths). This process typically requires software like Adobe Il****rator or Inkscape. You can manually trace the image using pen tools to create precise lines, or use an automatic tracing feature to convert the shapes and colors. Vectors are ideal for logos, il****rations, and designs requiring scalability without loss of quality, as they can be resized indefinitely while maintaining clarity.
