Browser-side marketplace check

Marketplace Image Checker

Start with a general marketplace preflight, or choose Etsy, Amazon, TikTok Shop, Shopify, eBay, or Walmart for platform-specific image warnings.

Short answer: Use the marketplace image checker as a general preflight first, then choose Etsy, Amazon, TikTok Shop, Shopify, eBay, or Walmart for platform-specific warnings. It checks technical metadata locally and keeps final approval items as manual review reminders.

ListingPic is an independent tool and is not affiliated with Etsy, Amazon, TikTok Shop, or their parent companies. This checker does not guarantee marketplace approval.

Choose what to check

General preflight or platform-specific rules

Start with General for common marketplace risks, or choose a platform to apply Etsy, Amazon, TikTok Shop, Shopify, eBay, or Walmart-specific warnings.

General mode is not final platform approval. Platform modes add marketplace-specific technical warnings and manual review reminders, using the same local browser-side checker.

Upload one JPG, PNG, or WebP image. Files stay in your browser.

Checks run locally with browser APIs. Image content, EXIF, hashes, filenames, SKUs, brands, and free text are not sent to analytics.

State: idle

Best fit

Who should use this checker?

Use it when

  • • You want to catch size, crop, format, or file-size problems before uploading.
  • • You need a private browser-side check for unreleased product photos.
  • • You want a quick preflight before opening a marketplace-specific resizer.

Do not use it as

  • • A guarantee that Etsy, Amazon, TikTok Shop, or another marketplace will approve the listing.
  • • A substitute for current category, region, or seller-account policy review.
  • • A legal review for claims, trademarks, watermarks, props, or text overlays.

Checker summary

What this checker actually tests

  • ListingPic Marketplace Image Checker is a browser-based product photo preflight tool for ecommerce sellers.
  • It checks image dimensions, aspect ratio, file size, format, and browser-readable metadata before upload.
  • It is best suited for Etsy, Amazon, TikTok Shop, Shopify, eBay, Walmart, and other marketplace workflows.
  • Images are checked locally in the browser and are not uploaded to ListingPic servers for the core checker workflow.
  • ListingPic is independent and cannot guarantee final marketplace approval.

Why use a marketplace checker instead of a generic resizer?

Generic resizers change dimensions but do not warn you about marketplace-specific crop, format, or file-size risks before you publish. ListingPic checks browser-readable properties locally so you can catch shared ecommerce upload issues first, then switch to a platform-specific checker for tighter warnings.

  • Checks run locally in your browser — image content is not uploaded to ListingPic for the core checker workflow.
  • Separates measurable file checks from manual review reminders so you know what still needs human judgment.
  • Does not guarantee marketplace approval; final decisions depend on current platform policies.

What ListingPic checks across marketplaces

Use the marketplace checker as a hub when the same product photo may be used across Etsy, Amazon, TikTok Shop, Shopify, eBay, Walmart, or another selling channel. General mode catches shared size, ratio, format, and file-weight risks; platform modes add marketplace-specific warnings and manual review reminders.

  • Image width and height
  • Aspect ratio and crop-readiness signals
  • File size
  • File format
  • Basic browser-readable metadata

What ListingPic cannot check automatically

ListingPic does not guarantee product approval and cannot automatically verify every visual, legal, or category-specific rule.

  • Whether a marketplace will approve the final listing
  • Category-specific or region-specific seller-program rules
  • Whether claims, text overlays, props, or promotional badges are allowed
  • Rules that require a human visual review in the current marketplace help center

How to fix image issues after checking

If ListingPic flags a size or ratio issue, create a cleaner marketplace-specific version before upload. Use white padding when you need to keep the full product visible, or crop only when the product has enough safe margin.

Sources and verification

ListingPic checks browser-readable image properties such as dimensions, aspect ratio, file size, and format. Marketplace rules can change by region, category, seller account, and upload surface, so visual policy items still require manual review in the current marketplace help center.
