Amazon White Background Requirements: The RGB 255,255,255 Rule Explained

The Background Rule, in Amazon's Words

Amazon's main image background has one allowed colour. Its shoes style guide puts it like this:

"MAIN images must have a pure white background (pure white blends in with the Amazon search and product detail pages - RGB color values of 255, 255, 255; hex #FFFFFF)." (Amazon shoes style guide (2019)).

Its Spring 2021 clothing guide says the same thing: "MAIN images must have a pure white background (RGB Value 255, HEX Value #FFFFFF)." (Amazon clothing imaging guide (2021)).

That one sentence contains both the rule and the reason. The background has to be exactly white so the image disappears into Amazon's white page, with no grey box around the product. The Amazon image requirements guide covers the rest of the main image rules.

This guide covers:

• What RGB 255, 255, 255 means, and why "looks white" is not a test
• What happens when a background is not white
• How to check a background properly
• Why JPEG exports leave near-white pixels, with our measurements
• How to get a background to exactly 255

What RGB 255,255,255 Means

In an 8-bit RGB image, each pixel has three channel values: red, green and blue. Each runs from 0 (none) to 255 (full). The range stops at 255 because each channel is stored in 8 bits, which hold 256 values.

• (255, 255, 255): pure white
• (254, 254, 254): one step below white. The difference can be difficult to spot on screen; measure the exported pixel values
• (250, 250, 250): very light grey. Still looks white on most screens
• (240, 240, 240): light grey. Visible against a white page

"Looks white" is not the same as white. A background at 250 looks white in isolation. The difference only shows when the image sits on a page of true white, as a faint grey rectangle.

How Close Is Close Enough?

Amazon's 2019 clothing style guide answers this directly. Among its prohibited images:

"Images with a non-pure white background (RGB less than 255)" (Amazon clothing style guide (2019)).

So 254 is not close enough. Amazon doesn't say how it measures a background, but the line is 255.

ComplianceKit uses the same line: any background pixel with a channel below 255 counts as off-white.

What Happens When It Isn't White

Amazon's current Image suppression help page lists it as a reason to hide a listing from search: "Main image has a background that is not pure white (RGB 255 255 255). Submit a compliant image to lift the suppression." (Amazon Image suppression).

Its older category guides were as direct:

• Shoes guide (2019): "Failure to meet those requirements will result in the suppression of your ASIN from search and could result in the suspension of your seller account." (Amazon shoes style guide (2019)).
• Clothing guide (Spring 2021): "FAILURE TO MEET THESE REQUIREMENTS MAY RESULT IN THE REMOVAL OF YOUR ASIN FROM SEARCH." (Amazon clothing imaging guide (2021)).

Detection is not instant. On Amazon's Seller Forums, its community manager team wrote that "it may take some time for the system to detect" images that break the requirements. An off-white background that is still live is not evidence it is fine. It may not have been caught yet (Amazon forum: enforcement timing).

How to Check a Background

Method 1: Eyedropper at Several Points

In Photoshop:

1. Select the Eyedropper Tool (I)
2. Set Sample Size to Point Sample, so you read one pixel rather than an average
3. Open the Info panel (Window → Info)
4. Hover over the background and read the RGB values

Where to check:

• All four corners
• The middle of each edge
• Right next to the product, all the way round
• Under the product, where a shadow would fall

Pure white reads R 255, G 255, B 255 at every point. The spots next to the product matter most. That is where shadows, fringing and compression do their damage, and where a corner check will miss it.

In GIMP: use the Color Picker tool with Sample average turned off, and read the values in its info window.

Method 2: A Threshold Check

A quick way to find problem areas across the whole background in Photoshop:

1. Add a Threshold adjustment layer
2. Drag the threshold level all the way up, to 255
3. Near-white areas turn black, so shadows, halos and a grey backdrop show up as dark shapes against the white
4. Delete the adjustment layer when you're done

Treat this as a way to find problem areas, then confirm them with the eyedropper. Threshold works on brightness, so a slightly tinted pixel can look fine here and still not read 255, 255, 255.

Method 3: Automated Check

ComplianceKit finds the product, then checks every pixel outside it against 255, 255, 255. It reports how many are off-white and marks them in red on your image, so you can see whether the problem is a shadow, a halo or the whole backdrop.

Common White Background Mistakes

Mistake #1: Trusting the Backdrop

The problem: the product was shot on white paper or a white sweep, so the background is assumed to be white.

Why it fails: a physical backdrop photographs as whatever the light made of it. Falloff at the edges, a slightly warm light or a backdrop that is not quite white all land below 255.

The fix: treat the backdrop as a starting point. Check the values, and replace or correct the background in editing.

Mistake #2: Shadows and Colour Casts

The problem: the backdrop is bright, but the product casts a shadow, or the light tints the background.

What it looks like in the numbers:

• A shadow under the product: grey values such as (230, 230, 230)
• A warm light: a lower blue channel, such as (255, 255, 245)
• A cool light: lower red and green, such as (250, 250, 255)

The fix: remove the shadow in editing (see below), and correct white balance before you judge the background.

Mistake #3: Exporting as JPEG

The problem: the background is exactly 255 in your editor, and the exported JPEG is not.

Why it happens: JPEG compresses the image in small blocks and approximates sharp edges. Where the product meets pure white, that approximation leaves pixels just below 255, in a halo around the product and sometimes several pixels away from it.

What we measured. We took a 1200 x 1200 product photo whose background is exactly 255 on all 1,065,515 of its background pixels, saved it four ways, and re-checked those same pixels:

Invisible on a screen, and not 255. Raising JPEG quality reduces the count but does not remove it — quality 95 still moved seven thousand pixels. That is why ComplianceKit's fix outputs PNG.

You can repeat this: the test image and the method are in image format requirements.

The fix: if you need a background with zero off-white pixels, export as PNG. Amazon accepts PNG. (Amazon Product image guide) The trade-off is file size: a detailed photo can be many times larger as PNG (see image format requirements).

Mistake #4: Feathered or Soft Edges

The problem: the cutout's edge is feathered, so pixels at the edge blend product colour into white.

Why it matters: a blended pixel is neither product nor pure white. Depending on where the product outline is drawn, it can count as off-white background.

The fix: keep the product's edge hard. In Photoshop's Select and Mask, leave Feather at 0. ComplianceKit's fix goes a step further and trims the outermost edge pixels, so no blended pixel touches the white.

Mistake #5: Leaving the Background Transparent

The problem: the background was removed and the file saved as a PNG with transparency.

Why it fails: transparent is not white. The requirement is a white background, and a transparent pixel has no colour of its own. Amazon does not document how it treats one (Amazon Product image guide).

The fix: put a layer of exactly 255, 255, 255 behind the product and flatten before exporting.

How to Get a Background to Exactly 255

Method 1: Cut Out and Replace (Most Reliable)

In Photoshop:

1. Select the product: Select → Subject, or the Object Selection Tool
2. Refine: open Select and Mask. Check the edge, keep Feather at 0, and use Decontaminate Colors if the old background has tinted the edge
3. Output the selection to a new layer with a layer mask
4. Add white: create a new layer below the product and fill it with white (Edit → Fill → White)
5. Verify: eyedropper the white layer. It should read 255, 255, 255
6. Flatten: Layer → Flatten Image
7. Export as PNG for zero off-white pixels, or as JPEG accepting some near-white pixels around the edge (see Mistake #3)
8. Check the exported file, not the Photoshop document

Method 2: Brighten a Nearly White Background

If the backdrop is already very close to white and evenly lit:

1. Add a Levels adjustment layer
2. Drag the white input slider left until the background reads 255 at every check point
3. Mask the adjustment off the product if it starts to blow out white or pale parts of it

This works for an evenly lit background that is already close to white. It does not remove a real shadow without also brightening everything else that dark, so use Method 1 for shadows.

Method 3: Automated Background Removal

Tools such as remove.bg and Adobe Express remove backgrounds automatically. They are quick and good on most products.

Always check the output:

1. Download the cutout as a PNG with transparency
2. Put it on a layer of exactly 255, 255, 255
3. Flatten, export, and check the exported file's background values

Automated cutouts are most likely to go wrong on hair, fur, glass, and white products on white.

ComplianceKit's fix does all of this in one step: it cuts the product out, frames it on a square of exactly 255 and exports PNG. Make a product photo's background pure white: the first fix is free, with no account.

Removing Shadows

A shadow on the background is off-white: grey pixels outside the product. Amazon's rule is a pure white background, so the shadow has to go (Amazon Product image guide).

If you cut the product out (Method 1), the shadow goes with the old background. This is the cleanest route.

If you're editing the original:

1. Select the shadow area with the Lasso or Quick Selection tool, staying clear of the product
2. Fill it with white (Edit → Fill → White)
3. For soft shadow edges, check the transition with the eyedropper and extend the fill until every pixel reads 255

Avoid the Clone Stamp for this. It copies texture and near-white noise from wherever you sample.

Fixing Colour Fringing

A thin coloured or grey outline around the product after background removal comes from two things: the old background colour bleeding into the edge pixels, or chromatic aberration from the lens.

Fixes in Photoshop:

• Decontaminate Colors in Select and Mask replaces the tinted edge pixels with nearby product colour
• Select → Modify → Contract by 1 or 2 pixels before outputting the cutout drops the fringe entirely, at the cost of a very slightly smaller product edge

Checklist Before Upload

Background:
☐ The background reads 255, 255, 255 at the corners, the edges, and right next to the product
☐ No shadow under or beside the product
☐ No grey halo or coloured fringe around the edge
☐ No transparency: the image is flattened onto white
☐ The exported file was checked, not just the editing document

Export:
☐ PNG if you need zero off-white pixels. JPEG can introduce off-white edge pixels; all three JPEG exports in our format test did

The rest of the main image:
☐ For ComplianceKit’s fill check, the product's longest side spans at least 85% of the frame. Amazon does not specify this measurement method (see the 85% fill rule)
☐ No added text, logos or watermarks (see text and logo rules) (Amazon Image suppression).

Summary: Key Takeaways

✅ The rule: "RGB color values of 255, 255, 255; hex #FFFFFF", from Amazon's style guides (Amazon shoes style guide (2019)).
✅ The reason: "pure white blends in with the Amazon search and product detail pages"
✅ Tolerance: ComplianceKit checks with zero tolerance; Amazon does not publish its pixel-level detection method. Amazon's 2019 clothing guide prohibits "RGB less than 255", and our target is RGB 255,255,255 (Amazon clothing style guide (2019)).
✅ Consequence: Amazon's guides say suppression from search, though detection can take time (Amazon Image suppression; Amazon forum: enforcement timing).
✅ Check several points, especially right next to the product
✅ JPEG leaves near-white pixels even at quality 95; PNG left none in our tests
✅ Keep edges hard, remove shadows, and flatten onto exactly 255
