White background product photos

Why marketplaces insist on white

A marketplace search page is a grid of small squares. If every photo carries its own background, a wooden table here, a living room there, a grey studio sweep in the next square, the grid turns into noise and the eye has to work to compare one item with the next. A shared white ground removes that variable, so the only thing changing between squares is the product itself.

The second reason is the one that matters commercially: a cutout is reusable. A product isolated on white, or better still on transparency, can be dropped into an ad, a banner, a category header, a printed catalogue page, a size comparison or a bundle shot without another photo session. A product photographed on your kitchen table can only ever be that photo.

And the third, less glamorous one: consistency across your own catalogue. Twenty products shot on the same white ground look like a brand. Twenty products shot on twenty different backgrounds look like twenty different sellers.

What the sites actually ask for

Requirements differ from marketplace to marketplace and they get revised, so treat what follows as the shape of the rules rather than the rules themselves. Amazon, eBay and Etsy each publish their own image requirements page, and it is worth reading the current one before a large upload. What is consistent across all of them:

• A pure white or very light background on the main image, with the product cleanly separated from it.
• The product filling most of the frame. Sites usually state a percentage of the frame the product should occupy; leave a small, even margin rather than cropping hard to the edges.
• No watermarks, logos, borders, text overlays, promotional badges, props or extra objects in the main image. Those belong in the secondary images.
• Enough resolution for the zoom viewer. Marketplaces set a minimum long side, and often a larger threshold before zoom is enabled on the listing at all. Shoot bigger than you think you need.
• A fixed aspect ratio, frequently square, on the main image.
• JPEG for the upload in most cases. Some sites accept PNG; practically all accept JPEG.

Two of these catch people out. The zoom minimum is the first: if your photo is short of the pixel threshold, running it through the upscaler is a legitimate fix as long as the original is sharp, since an upscaler adds resolution but cannot add focus. The second is the no-props rule on the main image. Lifestyle shots, scale references and detail crops are all welcome and they sell well, just not as image number one.

The halo, and why it happens

The grey, green or white rim you see around a cheap cutout is a resolution problem, not a matter of taste. Many background removers compute the mask on a downscaled copy of your photo, 512 or 1024 pixels on the long side, because that is the size the segmentation model was trained at, and then stretch that small mask back over a 12 or 24 megapixel image. Every mask pixel becomes a block of a dozen image pixels, the boundary lands in the wrong place, and a rim of the old background survives all the way around the product.

The second cause is the mask being binary. A pixel on the rim of a wine glass, a strand of hair, a fabric fringe or a brush bristle is not entirely product and not entirely background: it is a mix of both. A hard in-or-out mask has no way to express that, so it either keeps the whole pixel, including the colour of the background it was blended with, which is the rim you can see, or throws it away, and the edge goes jagged.

Doing it properly takes two things. The edge has to be refined at the full resolution of the photograph rather than at thumbnail size. And the partially transparent pixels need foreground estimation: working out what colour the product itself would be at that pixel, separately from the background it was mixed with. Without that step, a product shot against a green wall keeps a green tint along every edge when you move it on to white, and no amount of erasing fixes it.

Airpic uses BiRefNet for the segmentation, refines the edges at full resolution and estimates the foreground, which is why hair, fur, fabric and transparent edges come out without a rim. It is still worth checking the result at 100 percent before you push fifty listings live; the comparison viewer in the tool has a button for exactly that.

You can help yourself at the shoot too. Put distance between the product and whatever is behind it so the background falls out of focus and light does not bounce back off it, avoid strongly coloured surfaces and coloured light, and if you can, do not shoot a white product against white.

Pure white or transparent?

The short answer: export transparency as your master and generate solid backgrounds from it.

A PNG with an alpha channel holds the cutout and nothing else. From that one file you can place the product on white for the marketplace, on your brand colour for a banner, on a dark ground for a seasonal campaign, or over a lifestyle photo for an ad, without cutting it out again each time. Upload the PNG directly wherever the site accepts transparency.

Solid white is what you upload where the site requires a solid background or only accepts JPEG. JPEG has no alpha channel at all, so if you save a transparent PNG as JPEG the transparent area becomes whatever the software decides to fill it with, and in a lot of tools that is black. Ask for a white background at export time instead of converting afterwards and hoping.

On the shade of white: pure #FFFFFF is what marketplaces want, because it merges with the page and makes the product appear to float in the listing. On your own site a very light grey, something around #F7F7F7, often reads better, because the product gets a visible edge instead of dissolving into a white page. Airpic will give you transparent, white, black or any hex colour you type, so both versions come from the same photo in two passes.

Our guide to removing an image background goes further into the awkward cases: reflective surfaces, glass, and white on white.

Step by step in Airpic

1. Open the remove background tool.
2. Drop the photo on the card or paste it with Ctrl+V or Cmd+V. JPG, PNG with alpha and 16-bit, WebP, TIFF, HEIC and AVIF all work; the EXIF orientation is applied and the colour profile is preserved.
3. Pick the background: transparent, white, black, or type a hex colour.
4. Process, then inspect the edge. Use the 100 percent view and look at the places that fail first: hair, fur, handles, straps, mesh, glass and anything out of focus.
5. Download. For a marketplace main image that usually means a white background exported as JPEG. Run it a second time as a transparent PNG and keep that as your archive copy.
6. If the site wants more pixels than your photo has, upscale it afterwards. If the upload limit is tight, put the final file through compress, which is free to process and download.

If your product photos come off an iPhone as HEIC, convert them to JPG first so the marketplace uploader accepts them.

No account and no subscription. Processing and previewing the result are free; on the tools other than compressing you get one full download free every month, and after that credits that never expire, with the current details on the tool page. Your file is deleted an hour after you download it and one day at the most, it is never used to train a model, and the GPUs run in the European Union.
