Professional White Background Maker

The marketplace white-background spec, in one preset

White background is the universal marketplace baseline, but the precise spec varies more than most sellers realise. Amazon's Product Image Requirements (Seller Central help docs, last reviewed by Amazon in 2025) lock the main slot to RGB 255/255/255 background with the product plus its cast shadow filling ≥85% of the frame, JPEG under 10 MB, 1000 px minimum on the longest side to activate the zoom viewer with 1600–3000 px recommended. eBay's image policy (eBay Seller Center) requires 1600×1600 minimum to qualify for the zoom-and-pan viewer that boosts conversion in their A/B-tested grid. Walmart Marketplace's Item Setup spec mandates 2200×2200 on a pure white background and rejects margins, padding, or off-white casts at upload. Shopify's image API documentation recommends 2048×2048 source files for retina theme rendering. Google Shopping's Merchant Center product feed requires ≥800×800 and downgrades feed quality scores for non-white product images. The single thread tying these together is exact pure white at #FFFFFF — every other constraint stacks on top of that backbone.

The cutout pipeline here runs entirely in your browser via WebAssembly — the source product photo never leaves your machine, never lands on a third-party server, never enters a queue any other party can audit. That on-device privacy story (documented in detail at /private-background-remover/) matters concretely for three commercial scenarios: pre-launch SKUs under manufacturer NDA, supplier catalogue photos that resellers process before listing, and brand-controlled product imagery for paid ad creative where leak risk has a real dollar cost. The license documented at /commercial-use-background-remover/ confirms the export is permitted for paid commercial use — client-deliverable catalogs, sponsored ads, print-on-demand source files, and any other revenue-generating channel — with no per-image royalty and no usage cap. The combination (private + commercially licensed) is the differentiator versus cloud-processed competitors where one or both legs are paywalled.

How the time-and-money math actually works against the alternatives

The competitive landscape for white-background catalog prep is uneven. remove.bg (Canva-owned) caps free downloads at 0.25 megapixels (roughly 500×500), which is well below Amazon's 1000-px floor and far below Walmart's 2200-px requirement — the free output is unusable for any major marketplace main slot. HD downloads on remove.bg require paid credits at a per-image rate, and their terms restrict free output to non-commercial use. Photoshop (Adobe Creative Cloud, $22.99/month Photography plan) ships the right format and full control but the per-SKU time cost (open file, magic-wand or pen-tool cutout, fill layer at #FFFFFF, resize to spec, export) typically lands in the 4–7 minute range per image — a 200-SKU catalog refresh runs into a full work day. Canva Pro ($14.99/month) bundles a Background Remover but the export resolution is paywall-gated. The cutout here delivers full-source-resolution PNG or sRGB JPEG with the marketplace preset applied in a single pass, free, no signup, no watermark, no commercial-use restriction. For batch catalog work, /bulk-background-remover/ extends the same pipeline to hundreds of SKUs in one session.
