Marketplaces, ID photos and print shops all ask for white. Remove the old background first — the cutout drops onto white with zero halo.
Amazon and TikTok Shop main images require pure white — transparency alone doesn't qualify.
Passports and visas demand white or off-white behind the head. Clean cutout, no shadow line.
White isolates the subject in catalogs, flyers and business cards without clashing.
Workflow: remove the background above → open the transparent PNG over a white canvas (any editor, even PowerPoint) → export. The two-step keeps edges sharper than one-click "white background" filters, because the subject is never blended with the old background.
