Background removal
Background removal is the process of separating a product from everything behind it, producing a cut-out that can be placed on pure white or into a new scene.
Background removal used to mean a clipping path, an outline drawn by hand around the product in an image editor. Today it is mostly done by image segmentation models that estimate, pixel by pixel, what belongs to the product, producing an alpha mask whose soft edges let the cut-out blend onto a new background.
It exists to meet background rules. Amazon's main image needs a pure white background (RGB 255, 255, 255), Walmart asks for seamless white 255/255/255 RGB, and TikTok Shop asks for pure white on the main image. Etsy allows editing tools, AI included, to change backgrounds as long as the item does not look different from what the buyer receives, but most Etsy listings still need at least one real, unedited photo on a real background, and Etsy does not accept transparent PNGs.
The failures are at the edges. A halo of the old background stays around the product. Thin parts such as straps, cables, spokes and fur are cut away or left solid with background between them. Transparent glass and clear plastic lose their transparency. Some tools also remove parts of the product or keep props that are not included, which breaks Amazon's only-included-accessories rule.
Check the cut-out at full size on a dark background before placing it on white; halos and missing pieces show up clearly that way.
PicBarn's main image tab uses Bria background removal and places the product on RGB 255 at 85% of the frame, without redrawing the product pixels.
