Fix Non-Pure White Background
Fix off-white or slightly gray backgrounds that cause marketplace rejection. Ensure your white background is exactly #FFFFFF (RGB 255,255, 255) for Amazon, eBay, and Etsy.

Verifying True White Before You Upload
White can look warm because of the display, or the file itself can contain off-white pixels. Sample the exported background in an editor to distinguish those cases. A color check is one part of reviewing a product image, not proof of overall listing compliance.
The three-point eyedropper check
Open the export in any editor and sample three spots: a corner, the middle of the background, and a point a few pixels from the subject edge. Corners and mid-field prove the canvas is 255,255, 255. The near-edge sample matters most, because compression artifacts cluster along high-contrast boundaries.
Where JPEG hurts and where it does not
JPEG compression can change pixels near a high-contrast product edge. Inspect the actual export rather than assuming a particular quality setting will pass a checker. PNG avoids JPEG compression artifacts, but the subject mask and background still need review.
Warm screens lie about white
Night mode, True Tone and display settings can make white appear warm. If background samples read 255,255, 255, the sampled pixels are white; dimensions, crop and content requirements remain separate checks.
Do not brighten your way out
Brightening the whole photograph can also clip pale product detail. Prefer removing the old background and compositing onto white, then compare the product and soft edge with the original. A segmentation mask can still change which edge pixels are kept.
If a marketplace reports a problem, read the actual rejection reason and inspect the exported file. Background color, dimensions, crop and category restrictions are separate issues; correct the reported problem and review the result again.
The Problem
The exported background may contain off-white pixels, or display settings may make white look gray. Where a destination requires #FFFFFF for a main image, inspect the file pixels and the other listing requirements separately.
Common Causes
Step-by-Step Solutions
Select the pure white preset in Change Background tab
Go to the Change Background tab and select the white color preset from the solid colors section. This sets the background to exact #FFFFFF, which is pure white at RGB(255,255, 255).
Ensure you are using solid white, not a gradient
Check that the background type is set to Solid Color, not Gradient or Pattern. White gradients will have non-white areas that fail marketplace validation. The solid white option provides uniform pure white.
Download as PNG for exact color preservation
Use PNG format when downloading your image. PNG is lossless and preserves the exact #FFFFFF color value. JPEG compression can shift white pixels to slightly off-white values (e.g., 252,253, 254).
Verify in an image editor that background reads RGB(255,255, 255)
Open the downloaded image in any image editor and use the color picker or eyedropper tool on the background area. Confirm it reads R:255, G:255, B:255. This is the exact value marketplaces require.
