Use clear subjects for cleaner cutouts

Background removal works best when the subject has clear edges and good contrast against the background. Product photos, portraits, icons, and simple object shots are usually strong candidates.

Very busy backgrounds, motion blur, transparent glass, and fine hair can require manual review. After removing the background, zoom in around the edges before publishing the image.

Export as PNG when you need transparency

Use PNG when you want to place the subject on a new background, ecommerce card, presentation slide, or social media design.

If the final image does not need transparency, place it on a solid background and convert it to WebP or JPG to reduce the file size.
