Walmart catalog images

Walmart shoppers expect zoomable gallery squares and fast PDPs. Match the recommended frame, compress in one pass, then upload in Seller Center.

  1. 1
    Upload
    Collect catalog images (PNG, JPEG, WebP, or a ZIP). Open image tools and start in Bulk Resize if you need consistent frame sizes first, or go straight to Bulk Compress if pixels are already correct.
  2. 2
    Optimize (resize)
    In Bulk Resize, pick the Walmart Product preset (2200×2200) or match your category's required aspect ratio with custom width and height. Optional: Bulk Convert if you need JPG for upload. See the Walmart image resizer guide.
  3. 3
    Compress
    Run Bulk Compress so storefronts and listing pages load quickly on mobile. Start with High Quality, then try Balanced if portals still reject file size. Tips: bulk image compressor.
  4. 4
    Quick checks
    Confirm dimensions, format, and file size against Walmart's latest listing rules (borders, text, backgrounds). Policies change — use your Walmart Seller Center checklist as the source of truth before you publish.
  5. 5
    Export (ZIP)
    Each tool ends with Download ZIP. Unpack, verify a sample listing in preview, then upload in Walmart Seller Center. Premium keeps saved downloads longer — see pricing.
