WhiteBackground.app

WhiteBackground.app is an online photo editor for making image backgrounds pure white. Its free single-photo workflow removes a background locally in the browser, centers the subject on RGB 255, 255, 255, and downloads a JPG or PNG. No account is required for free local processing, and photos are not uploaded in this mode. The editor supports JPG, PNG, WebP and iPhone HEIC inputs, transparent PNG composition, square and custom output sizes, and adjustable subject spacing. Brush tools let users erase or restore details and undo or redo edits. Free photo exports have a maximum edge of 2200 pixels. It is useful for product catalogs, marketplace listing pictures and simple portraits.
