Walmart Marketplace Image Requirements: Seller Guide (2026)

Walmart Marketplace has strict image requirements similar to Amazon. The main product image must feature a white background, meet minimum dimension requirements, and avoid text overlays or promotional content. Walmart uses automated image quality checks during the listing process.

Walmart allows up to 10 images per product listing. The primary image (Swatch image) appears in search results and must meet all requirements. Additional images can show the product from different angles, in use, or with infographic content.

Minimum: 640x480 pixels.

**Recommended:** 1600x1600 pixels for the best customer experience and zoom functionality.

**Maximum:** 3000x3000 pixels.

**Aspect ratio:** Square (1:1) recommended for consistent display across Walmart.com and the Walmart app.

**Best practice:** Upload at 1600x1600 pixels. This meets all requirements, enables zoom, and displays well on all devices.

Walmart requires a white background for the primary product image. This is similar to Amazon's requirement.

**What Walmart checks:** - Background should be pure white or very close to it - No visible shadows on the background - Product should be the sole focus of the image - No lifestyle or contextual backgrounds on the primary image

**How to fix:** Use IsoPeel Background Remover to create a guaranteed pure white background. The AI removes any existing background and replaces it with clean white.

**Secondary images:** Walmart allows lifestyle photos, infographics, and styled images for additional image slots.

Accepted formats: JPEG, PNG, BMP.

**Maximum file size:** 10MB per image.

**Recommended format:** JPEG for photographs, PNG for images needing transparency.

**URL-hosted images:** Walmart also accepts image URLs during bulk listing creation. Images must be publicly accessible and meet the same format/size requirements.

1. Non-white background — Lifestyle photos as the primary image will be rejected.

**2. Text overlays** — Promotional text, price callouts, or badges on the primary image.

**3. Watermarks** — Photographer or brand watermarks on any listing image.

**4. Low resolution** — Images below 640x480 pixels.

**5. Multiple products** — The primary image should show the single product being sold (multi-packs can show all included items).

**6. Borders or frames** — Decorative borders around the product image.

1. Match Amazon standards — If you already sell on Amazon, your Amazon-compliant images will generally meet Walmart requirements too.

**2. Use 1600x1600 resolution** — This enables the best zoom experience on Walmart.com.

**3. Check compliance before uploading** — Use IsoPeel to verify images meet all Walmart requirements before listing.

**4. Use all 10 image slots** — Include hero shot, angle views, lifestyle images, size charts, and feature callouts.

**5. Optimize file size** — Keep images under 5MB for faster page loads while maintaining quality.

**6. Keep backgrounds white** — Use AI background removal for consistently pure white backgrounds across your entire catalog.
