What raster images are
Raster images such as PNG, JPG and JPEG are made from pixels. They are easy to use online, but when the same image is enlarged too much, the edges can look blurry or broken.
What vector files are
Vector files are made from paths, curves and shapes. This means the artwork can be resized for business cards, websites, packaging, signs and banners while staying sharp.
When conversion helps
Raster to vector conversion is useful for logos, icons, stickers, apparel artwork, labels, decals, print files and digital brand assets. A clean vector file is easier to edit and easier to reuse across professional workflows.
