Marketplace Main Image Requirements, Compared (2026)
Bottom line first: build one main image that is square, ≥1600px on the long edge, on a pure white background (RGB 255,255,255), with the product filling 80–85% of the frame and no text / logo / watermark / promo badge. That single image already meets the strict, hard requirements of Amazon, AliExpress, and Walmart; from there you only fine-tune per platform. The table below lists the exact numbers for the eight major marketplaces so you can compare and produce one cross-platform image at once.

| Platform | Recommended size (px) | Pure white bg (RGB 255) | Subject fill | Format / size | Banned in main image |
|---|---|---|---|---|---|
| Amazon | Long edge ≥1600px (enables zoom); max 10000px; 2000×2000 square recommended | Required: pure white RGB 255,255,255 | Product ≥85% of the frame | JPEG (preferred) / PNG / TIFF / GIF; sRGB advised | Text, logos, watermarks, promo copy, borders, multiple products, props (some categories excepted) |
| Shopify | 2048×2048 square recommended; max 4472×4472 / 20MP | Not required (keep a consistent white or brand background) | No hard rule (keep padding and style consistent) | JPEG / PNG / WebP / GIF; ≤20MB per image | No platform-level ban (your own store; but third-party listings must still comply) |
| eBay | Long edge ≥500px; ≥1600px recommended to enable zoom | Not required; white background advised (passes review, converts better) | 80–90% recommended, with a small margin | JPEG / PNG / GIF / BMP / TIFF / WebP; ≤12MB per image | Seller-added text / watermark / border on the first photo (eBay’s own frame excepted) |
| Temu | ≥800×800; 1350×1800 (3:4) or square preferred; long edge ≥1340px advised | Main image usually requires pure white / plain light background | Centered, high fill (~80%+), not touching edges | JPEG / PNG; usually ≤3MB per image | Text, collages, watermarks, QR codes, brand logos, exaggerated promo badges |
| AliExpress | Main image from 800×800; ≥1000×1000 preferred, supports zoom | White-background slot requires pure white RGB 255; main image best on white/light | ~80% of the frame, centered with margin | JPEG / PNG; ≤5MB per image | On the white-bg image: text / watermark / collage / cluttered promo badges |
| Lazada | 1000×1000 square recommended (min 330×330); ≥1080px preferred | Main image requires pure white RGB 255,255,255 | Product ≥85% of the frame, centered | JPEG / PNG; ≤5MB per image | Text, watermark, logo, border, promo badge, multiple products, models (main image) |
| Shopee | 1000×1000 square recommended (min 500×500); side up to ~4000px | Pure white not mandatory; white/light main image passes & converts better | Centered, high fill, ~10% safe margin all around | JPEG / PNG; ≤2MB per image | Heavy watermarks / big promo text / borders / irrelevant elements (hurts search & campaign eligibility) |
| Walmart | Long edge ≥2000px to enable hover-zoom; min ≥1000px; square | Main image requires pure white RGB 255,255,255 | Product ≥85% of the frame ("fills 100%" policy wording) | JPEG (preferred) / PNG; ≥1500px & sRGB preferred | Text, watermark, logo, border, accessories, multiple products, promo overlays |
What most platforms share (quotable)
- The main (first) image is almost always preferred or required to be: pure white background, single product, no text / watermark / border.
- Square 1:1 is the most universal safe ratio; a few platforms (e.g. Temu) also accept 3:4 portrait — keep a square and a portrait version.
- A long edge ≥1600px unlocks zoom / hover-zoom on nearly every platform (Amazon, eBay, and Walmart all gate on this threshold).
- "Pure white" means RGB 255,255,255 — not an off-white light gray. Amazon / AliExpress white-bg / Lazada / Walmart check the actual RGB value.
- Secondary images (from #2 on) are far more lenient: lifestyle, detail, dimension, and feature shots are fine — strict main, flexible extras is the universal model.
How to make one cross-platform main image (4 steps)
Build to the strictest platforms (Amazon / Walmart / Lazada) and it works down-stack everywhere else:
Step 1: Cut out the background, fill pure white RGB 255,255,255
Remove the product from its original background and fill with pure white — not light gray, not a gradient. Checks read the per-pixel RGB value, so being slightly off can get rejected.
Step 2: Make it square 1:1, long edge ≥1600px
Set a square canvas with the long edge at least 1600px (2000px preferred) to unlock zoom everywhere; keep the product centered.
Step 3: Fill 80–85% with a safe margin
Let the product fill the frame without touching the edges; leave ~10% padding on all sides so thumbnails don’t crop the subject.
Step 4: Remove text / logos / watermarks / promo badges
Keep the main image free of any text, brand logo, watermark, border, or promo badge — save those for the secondary images (#2 onward).
Risk note (read first)
- Platform policies change, and rules differ by category within the same platform (apparel, footwear, food, electronics) — before listing, defer to the latest requirements in that platform’s official seller center / help docs.
- These numbers summarize publicly stated specs as of mid-2026 for quick comparison; they are not a compliance guarantee — treat thresholds/amounts as authoritative only from the platform itself.
- "Pure white" is a machine RGB check — looks-white to the eye ≠ passes the check; export in sRGB and disable color-management shifts.
- Some categories (e.g. on-model apparel, jewelry that must show fit) have main-image exceptions — don’t apply the generic rule blindly.
- AI-generated main images must meet the same compliance rules (white bg / no text / subject fill); platforms review the result, not the generation method.
Frequently asked questions
Which platform has the strictest main-image rules?
Answer: Overall Amazon, Walmart, and Lazada are strictest: all three require a pure white RGB 255,255,255 background, ≥85% subject fill, and no text / watermark / logo on the main image. Build to their standard and you generally cover eBay, Shopee, AliExpress, and Temu. Shopify is the most lenient since it is your own store, but listings syndicated to third-party platforms must still comply with those platforms.
Which platforms require a pure white (RGB 255) main image?
Answer: Amazon, Walmart, and Lazada require a pure white RGB 255,255,255 main image; AliExpress requires pure white for its white-background image slot; Temu usually requires pure white or a plain light background. eBay, Shopee, and Shopify do not mandate pure white, but a white-background main image passes review faster and converts better, so a consistent white is recommended.
Can one main image work for all platforms?
Answer: Mostly yes. A main image that is square 1:1, ≥1600px on the long edge (2000px preferred), pure white RGB 255, subject at 80–85%, with no text / watermark / border, directly satisfies the strictest platforms (Amazon, Walmart, Lazada, AliExpress) and works for eBay / Shopee too. The only extra you may need is a 3:4 portrait version for platforms like Temu that accept it — keep both a square and a portrait.
Are AI-generated main images allowed on these platforms?
Answer: Yes. Platforms review whether the image is compliant (pure white background, no text, subject fill, truthful representation of the product) — not which tool created it. As long as an AI-generated main image meets that platform’s hard rules, it can be listed normally. Caveat: the image must not misrepresent the actual product (e.g. invent features or looks it doesn’t have).
What is the minimum pixel size, and how big should I go?
Answer: Hard minimums differ (eBay ≥500px, Shopee ≥500px, Lazada ≥330px), but to unlock zoom / hover-zoom Amazon and eBay need a long edge ≥1600px and Walmart needs ≥2000px. In practice, make everything 2000×2000 — one version covers all zoom needs without exceeding any platform’s ceiling.
Should the main image be square or portrait?
Answer: Prefer square 1:1 — it is the universal safe ratio for Amazon, AliExpress, Lazada, Shopee, and Walmart. Temu and some social-commerce placements favor 3:4 portrait (e.g. 1350×1800). The safest approach is a square main image as the baseline plus a separate 3:4 portrait for platforms / ad slots that need it.
