Listing image size & crop checker
Load a product image below to measure its pixels, aspect ratio, and centered square crop against current marketplace guidance. The file stays in your browser and is never uploaded.
Your image is read in your browser with FileReader and never leaves your device — nothing is uploaded.
Why one pixel rule gives sellers the wrong answer
Each platform expresses size differently. Etsy recommends at least 2000 pixels on both dimensions; Amazon describes its zoom threshold using either height or width; eBay sets a 500 × 500 minimum; Shopify's best-display guidance depends on the theme. A single shortest-edge test would misclassify at least one of them.
This checker evaluates the relevant edge for each platform and previews a centered square crop. A green size result is not a policy approval: background, content, category, rights, and accurate representation are separate checks.
It runs entirely on your device
Your browser reads the image locally to measure it and draw the crop preview. The pixels never leave your computer, there is no account, and the tool continues to work after the page has loaded even if you disconnect.
Marketplace listing image requirements
Marketplace requirements and recommendations as published in each platform's seller documentation. Rules change and category requirements can be stricter, so use this as a preflight—not a substitute for the current help center.
| Marketplace | Minimum | Recommended | Aspect | Notes |
|---|---|---|---|---|
| Etsy | 635 × 635 for first photo | 2000px+ both dimensions | Landscape or square first image | Original real-item photos required except limited mockup cases. |
| Shopify | No general floor stated | 2048 × 2048 | Theme-dependent; square common | Up to 5000 × 5000 or 25MP and under 20MB. |
| Amazon | 500px longest side | 1000px+ for zoom | Square commonly used for MAIN | MAIN: actual-product photo on pure white; category rules can add constraints. |
| eBay | 500 × 500 | About 1600 × 1600 | 1:1 or 16:9 often works best | No borders, text, artwork, or watermarks; used items need actual-item photos. |
Questions, answered plainly
Is my image uploaded anywhere?
No. The checker reads the file locally in your browser and stores no copy. After the page loads, you can disconnect and the measurement still works.
What does the square overlay mean?
It marks the largest centered 1:1 crop. It is a composition warning, not a prediction of every platform placement. If packaging or a handle falls outside it, make a dedicated crop rather than trusting an automatic thumbnail.
Why can an image pass size and still be rejected?
Pixel dimensions are only one rule. A platform may also regulate background, text, watermarks, real-item photography, category content, rights, and accurate representation. Always check the current policy for the listing itself.
Are these specs current?
They were checked against the linked official platform guidance on the retrieval date shown above. Before a large or high-stakes upload, open those sources again because marketplaces revise requirements.
