Your main image needs a pure white background (RGB 255,255,255), at least 1,000 pixels on its longest side (larger sizes enable a better zoom function), and the product filling a large majority of the frame. Amazon accepts JPEG, TIFF, GIF and PNG files in sRGB colour space. Secondary images give you far more flexibility, but a non-compliant main image is the single fastest route to listing suppression. If you fix nothing else this week, fix that.
TL;DR:
- Using a pure white background (RGB 255,255,255) for the main image is non-negotiable; faint halos or off-white shades cause rejection during automated checks.
- Main images should be at least 1,000 x 1,000 pixels, with 2,000 x 2,000 pixels recommended for sharper zoom functionality and better mobile conversions.
- Secondary images can include lifestyle, scale, infographic, component, or detail shots, with less strict background rules, but should target buyer questions effectively.
- Always export images in sRGB color profile and derive JPEGs from a TIFF master to avoid color shifts and ensure compliance during bulk uploads.
- Automated tools that connect to Amazon’s API help identify and fix image issues faster, prioritizing corrections based on revenue impact and visibility loss.

What are Amazon’s technical image specifications?
Every image you upload has to clear a baseline before Amazon even checks your background or props. The minimum is 1,000 x 1,000 pixels, but that number only just satisfies the zoom function that lets shoppers hover over your photo on the product page. Industry practitioners commonly recommend 2,000 x 2,000 pixels or larger because that resolution keeps the zoomed view sharp rather than pixelated, and sharper zoom images convert better on mobile.
Aspect ratio is generally expected to be square (1:1), at least for the main image, though Amazon tolerates some variation on secondary images. File size caps vary by category, but keeping individual images under 10MB is recommended to avoid upload errors. Colour space matters more than sellers expect: Amazon requires an sRGB colour profile, not Adobe RGB or CMYK, because browsers and Amazon’s own rendering engine assume sRGB. Export in the wrong profile and colours shift, sometimes enough to make a product look a different shade entirely.
On file formats, JPEG is typically used for listings due to balance of quality and file size because it balances quality and file size well. TIFF is recommended as a master archival format from which other versions are derived, from which every other version gets derived. PNG suits images with transparency needs during editing, though your final upload rarely needs it. GIF is technically accepted but almost never the right choice for product photography.
Getting the main image right: the rules that trigger suppression
Amazon enforces main image rules far more strictly than secondary image rules, and for good reason: the main image is what appears in search results, so it carries the heaviest weight for both compliance bots and buyer clicks.
The background must be pure white (RGB 255,255,255) for the main image, not an off-white or cream that looks fine to your eye but fails Amazon’s automated scan. Check all four corners of your image at high zoom; a faint grey halo left over from a poor cutout is one of the most common reasons for rejection under the product image guide. Your product should fill a large majority of the frame, which means cropping tighter than most sellers instinctively do; a product floating in a sea of white space looks weak on a mobile thumbnail where every pixel counts.
Certain elements are banned outright on the main image:
- No text overlays, badges, or promotional graphics
- No logos beyond what’s printed on the product itself
- No watermarks, borders, or drop shadows
- No props, packaging, or accessories that aren’t actually included
Before you upload, run three quick checks: preview the image at thumbnail size, verify sharpness at zoom, and sample corner pixels to confirm true white background to confirm true white rather than an off-white a viewer would never spot on screen.
Pro Tip: Amazon’s automated background check is stricter than the human eye. Use the eyedropper tool in Photoshop or GIMP to sample all four corners; anything reading above 250 on any RGB channel risks a rejection, even if it looks perfectly white to you.
How should you use your secondary images?
Amazon allows one main image plus multiple additional images per listing, and secondary images do not require a pure white background. That freedom is where most sellers under-perform, treating extra slots as an afterthought rather than a sales tool.
Structure your image stack to answer buyer questions in a logical order:
- Lifestyle shot showing the product in real use, establishing context the main image can’t
- Scale reference with the product next to a common object or a person, since size confusion drives returns
- Infographic highlighting one key benefit or feature, never more than one message per graphic
- What’s included shot laying out every component in the box
- Detail close-up on texture, materials, or a feature buyers ask about in reviews
Infographics need mobile-first thinking: most Amazon traffic is on a phone screen, so text smaller than roughly 24pt disappears the moment the image shrinks to thumbnail size. Keep margins generous and stick to a single message per slide rather than cramming five bullet points onto one graphic. Sequencing each slot to a specific buyer question tends to outperform a random scattershot of product angles.
Formats, naming and the upload attributes that trip sellers up
Run a two-tier workflow: create a TIFF master file and derive JPEG versions for upload. GS1’s product image specification recommends exactly this approach, keeping a lossless archive while deriving lighter web files with a clipping path applied for clean, precise cutouts.
Always export the final file in sRGB, never CMYK or Adobe RGB, since those profiles were built for print and shift colours on screen. When submitting via feed rather than direct upload, the image_link and additional_image_link attributes must contain clean, RFC-compliant URLs with no unencoded spaces or special characters, a common source of silent feed failures. Name files consistently, using your SKU or ASIN as the base, so nothing gets mismatched during bulk uploads.
Diagnosing and fixing the most common image rejections
Amazon’s rejection message usually points at the cause, but the wording is often vague enough that sellers guess wrong and waste a re-upload cycle. Start by reading the specific error code rather than assuming it’s always the background.
The most frequent causes are non-pure-white backgrounds, product fill below the 85% threshold, overlaid text or logos, and resolution under 1,000 pixels. Each has a direct fix:
- Off-white background: re-run the clipping path and re-check corner pixel values
- Insufficient fill: recrop tighter around the product
- Detected overlay: strip any added text, badge, or watermark and re-export clean
- Low resolution: reshoot or re-derive from your TIFF master at 2,000px or larger
Pro Tip: If a rejection message seems inconsistent with what you’re seeing, re-export at a fresh sRGB profile before resubmitting. Colour profile mismatches occasionally trigger a false background failure that looks like a white-background issue but isn’t.
A repeatable checklist for compliant images at scale
Running the same sequence for every SKU keeps quality consistent once you’re managing more than a handful of listings.
- Capture: shoot with even lighting, correct white balance, and a defined clipping path in mind, following the camera and lens guidance in GS1’s image standards
- Export: derive the 2,000 x 2,000px sRGB JPEG from your TIFF master, using a consistent SKU-based naming convention
- Pre-upload QA: run the corner white-sample test, preview at thumbnail size, zoom-check for sharpness, and confirm the image matches the correct variant before it goes live
How automation speeds up image compliance
Checking every SKU manually doesn’t scale once you’re past a few dozen listings. Automated scans can flag missing images, undersized files, or off-white backgrounds across your entire catalogue in minutes rather than hours of manual review.
The bigger win is prioritisation. Not every flagged image deserves urgent attention; a suppressed best seller losing visibility matters far more than a slow mover with a slightly soft secondary shot. Sorting fixes by lost impressions or click-through rate, rather than working through listings alphabetically, gets your highest-value corrections done first. Tools that connect directly to Amazon’s API, Osellpa’s listing tools among them, can surface suppressed listings and rank them by revenue impact rather than leaving you to hunt through Seller Central manually.
Fix visibility before chasing conversion gains
Get the main image compliant first. A suppressed listing earns zero impressions, so no amount of clever lifestyle photography or infographic polish matters until that’s sorted. Once visibility is restored, treat your secondary images as a testing ground rather than a finished product: Amazon’s Manage Your Experiments feature for Brand Registry lets registered brands A/B test main image variants directly. Measure click-through rate and conversion after every meaningful change, because a photo that looks better to you doesn’t always perform better to shoppers.

Let Osellpa handle the checking, so you can handle the fixing
Manually auditing image compliance across dozens or hundreds of SKUs eats hours you don’t have, and a single missed suppression can quietly cost weeks of sales before anyone notices. Some tools connect directly to Amazon’s API and pull performance data alongside listing health, so instead of scrolling through Seller Central hunting for problems, you get a prioritised view of which listings need attention first, ranked by lost visibility and revenue impact rather than guesswork.
That matters most if you’re managing a large catalogue or you’ve been hit by repeated suppressions and don’t have the resources to check every image by hand. Pair that visibility with Osellpa’s listing optimisation tools to fix flagged issues faster, or start with the seller dashboard to see where your current listings stand today.

FAQ
What are the required image dimensions for Amazon products?
The minimum image dimension is 1,000 x 1,000 pixels; larger sizes, such as 2,000 x 2,000 pixels, are recommended for enhanced zoom functionality so the zoom function displays a sharp image rather than a pixelated one.
What are the photo requirements for an Amazon badge?
Badge eligibility (such as Amazon’s Choice or Climate Pledge Friendly) doesn’t have separate photo rules; it depends on your main and secondary images already meeting the standard pure white background, 85%+ fill, and no prohibited overlay requirements.
Why won’t my photos upload to Amazon?
Upload failures usually trace back to resolution below 1,000 pixels, a non-sRGB colour profile, an off-white background, or a malformed URL in the image_link attribute when submitting via feed rather than direct upload.
What size images work best for Amazon A+ Content?
A+ Content modules typically call for images sized according to the module chosen, and Amazon recommends sRGB JPEG or PNG files exported at high resolution to avoid blurring on larger screens.
How many images can I upload per listing?
Amazon allows up to nine images per listing: one main image plus additional images, though the main image alone carries the strict pure white background requirement.
