Will this actually pass Amazon's #FFFFFF check?

Yes. The 'Amazon Main Image' preset locks the output to pure #FFFFFF — not off-white, not near-white. We've tested it across thousands of listings.

My supplier sends product photos with busy backgrounds. Can I still use those?

That's exactly the use case. Paste your supplier's image URLs into the API — no need to download first — and get back white-background, listing-ready JPEGs in the API response.

I need transparent PNGs for A+ content. Is that a separate tool?

Same tool, different output setting. Choose 'transparent PNG' instead of 'white background' and you get a clean cutout with the same edge quality — ready to drop into A+ modules.

What Amazon checks on your main image — and how we handle each one

verified

Exact #FFFFFF white background

Not off-white, not cream, not light gray. Amazon's scanner flags anything that isn't pure white. Our preset outputs #FFFFFF every time — no exceptions, no shadows bleeding through.

open_in_full

85%–100% frame fill, auto-calculated

Too small in the frame = rejected. Too large = clipped on mobile. Our padding algorithm hits the sweet spot so your product fills the image exactly right.

zoom_in

High-res enough for zoom

Amazon's zoom feature requires 1600px on the longest side. We export full-resolution JPEG or PNG, and throw in transparent PNG for your A+ content layouts at no extra cost.

content_cut

Clean edges on any material

Chrome fixtures, glass bottles, sheer fabric, fuzzy toys — the edge model handles tricky materials so your product doesn't look like it was cut out with scissors.

grid_view

Category-specific aspect presets

Square for most categories, 1:1.2 for tall items like bottles. One click locks the right ratio — no guesswork, no manual cropping.

bolt

Bulk for high-SKU sellers

Upload multiple images at once in the dashboard. For bigger catalogs, the API accepts image URLs so you can process supplier feeds programmatically.
