What this marketplace image checker tests

This tool checks technical upload signals: pixel dimensions, aspect ratio, file format, file size, and whether your image matches a selected marketplace preset. It cannot verify subjective policy items such as whether a product is accurately represented, whether a background is truly pure white, or whether a listing complies with every category rule.

Etsy

Checks for large product photos and square or 4:3-friendly crops for listing previews.

Amazon

Checks whether the longest side supports zoom-friendly product image quality.

TikTok Shop

Checks square product images with at least 600 by 600 pixels.

eBay

Checks the 500-pixel minimum and a stronger 1600-pixel seller-friendly target.

Why sellers search for image size checkers

Marketplace sellers often discover image problems only after a listing upload fails, crops the product awkwardly, disables zoom, or makes a photo look blurry in search results. A dedicated marketplace image size checker is more useful than a generic image dimensions checker because it translates width, height, file weight, and format into platform-specific pass or fix guidance.

FAQ

Does this upload my image?

No. The checker reads and resizes the image in your browser with the File API and canvas.

Is this an official marketplace validator?

No. It is an independent technical checker for common upload and best-practice signals.

Can it remove watermarks or backgrounds?

No. It checks and resizes images. It does not remove watermarks or alter product content.

Which source rules should I verify before publishing?

Always verify current rules in the seller center or help page for the marketplace you use.

Source notes

The checker is based on public marketplace guidance from Amazon Seller Central, TikTok Shop Seller Center, eBay Help, and Etsy listing image policy pages. Marketplace rules can change, so use this as a fast pre-check rather than a final compliance guarantee.
