Check a product image before Amazon, Temu, TikTok Shop or Shopee rejects it
Upload one JPG or PNG. The checker measures pixel dimensions, aspect ratio, file type, transparency and the four corner background colors in your browser. Nothing is uploaded or stored.
Built from the same verified specifications used on the marketplace requirement pages. Category rules can add stricter conditions, so use this as a preflight check, not a guarantee of approval.
Local preflight
Upload one product image
This is a technical preflight. It does not verify product accuracy, category-specific rules, or platform approval.

What the checker catches
Size and ratio
Minimum and recommended pixels, plus the 1:1 lead-image ratio that most marketplaces expect.
Background cast
Samples all four corners to catch grey casts, uneven lighting and styled backgrounds.
File format
Flags formats a marketplace does not accept and warns when transparency is present.
Upload readiness
Separates technical failures from items that need a human review before publishing.

What it cannot verify
- Whether the product in the photo matches the SKU being sold
- Category-specific rules for apparel, beauty, consumables or variations
- Whether text, claims or badges are allowed in a particular gallery slot
- Platform review decisions, which remain human and can change

Does this checker upload my image?
No. The image is decoded and measured in your browser with the Canvas API. It is not sent to the server or stored.
Does a pass mean the marketplace will approve the image?
No. The checker verifies the technical baseline: pixel size, aspect ratio, file type, transparency, and corner background. Category rules, product accuracy, and review decisions still require a human check against the seller centre.
Why does the checker flag a white background?
It samples the four corners. A grey cast, a shadow, or a lifestyle background can fail a main-image rule even when the product itself looks clean. Pure-white and near-white platforms use different thresholds.
What image size should I use?
Use the recommended size for the platform when possible. Amazon main images target 1600 px or larger on the longest side, Temu and TikTok Shop target 1000 px, and Shopee targets 1000 px for the cover image.
Can I check a lifestyle gallery image too?
Yes, but the background and text rules are stricter for a lead image than for a gallery image. Use the preset that matches the role of the image you are checking.
