Listing Image Checker — Catch Rejections Before You Upload

The usual causes are a photo below the minimum pixel size, a background that is not exactly white, a product that fills too little of the frame, text or a logo burned into the main image, and the wrong shape. Marketplaces apply these checks automatically and rarely say which one failed, so the fastest way to find out is to measure the photo against the published rule before you upload it.

Amazon expects the product to fill roughly 85% of the frame in the main image on a pure white background. Images can be 500 to 10000 pixels on the longest side, with more than 1000 pixels preferred for zoom. This tool measures the product against the frame and reports the percentage it found, so you can correct the image before uploading.

Yes. Google Merchant Center is moving to a minimum of 500 by 500 pixels for every product image. Warnings started appearing in July 2026 and images below the new minimum are disapproved from 31 January 2027. An image that is legal today can still fail after that date, so the check flags it as a warning rather than a pass.

An automated marketplace check reads the pixel value, not the impression. A background at 250,250,250 looks white to a person and fails a pure-white rule. The check reports what share of the border is an exact 255,255,255 match, so you can see the gap before the marketplace does.

No. Every measurement runs inside your own browser tab, so the photo never leaves your device and there is nothing to delete afterwards. That is also why the result appears immediately with no queue.

Not reliably, so it does not pretend to. Burned-in text, logos and watermarks are listed as a manual check with a reminder of which destinations ban them. A false all-clear on that check is the one result that would actually cost you the listing, so it is left for your eyes.

Yes. The photo is measured once and scored against every destination from that single measurement, so the summary row shows at a glance which ones it passes. Selecting a different destination switches the detailed report instantly without re-reading the file.

Almost always one of three things. The file is over the 20 MB free upload limit — Premium takes 50 MB and Pro 120 MB. The format is not one this tool accepts, so check the list shown on the upload panel. Or the file is not really the format its name says: renaming a file does not change what is inside it, and that is the reason a valid-looking image gets refused.

Check the input first: a sharp, well-lit original that has not been through a messaging app gives the best result. Then review the settings on the page, change one at a time and run it again — nothing is locked in until you download.

Listing Image Checker supports free standard use within the published processing allowances. Free downloads are clean — no watermark. No signup is required for standard tool use. Photo effects and AI edits have a web-size limit on Free, with the original-resolution result available through Premium or one credit. Crop, resize, rotate, compress and convert stay full size. Published processing allowances and file limits still apply.

No — Listing Image Checker runs in the browser on desktop and phone. There is nothing to install, no trial to start, and no license to buy before you can see whether it does what you need. Try it on the file you are actually stuck with rather than a sample.

It opens PNG, JPG, WebP, GIF, BMP and AVIF files. Browsers cannot decode HEIC or TIFF, so the checker asks you to convert those to JPG or PNG first. That does not change which formats a marketplace accepts, which each report lists.

A pass is not a promise of acceptance. The checker measures what it can from the published rules, and each marketplace makes its own decision and can change its rules. Text and logos need your own check. Use a pass to catch common problems, and read the marketplace's current guidelines before you upload.

For a Walmart Marketplace primary image the checker tests a minimum of 1,500 pixels on each side, recommends 2,200, expects a square 1:1 image, a pure white background, sRGB color and a file under 5 MB. The report shows its source and the date the numbers were last checked.

The checker tests eBay at a minimum of 500 pixels on the longest side, recommends 1,600 and allows 7 MB. Etsy has no hard minimum and recommends 2,000 pixels on each side. Shopify recommends 2,048 pixels on each side and accepts up to 5,000 pixels, 25 megapixels and 20 MB.

It measures and reports, and its Fix it buttons open the matching tool, such as White Background Maker, Image Upscaler or Image Cropper, where you correct the file. Nothing is edited or saved by the checker itself, so it has no download.

It marks a check the tool cannot decide for you. Burned-in text, logos and watermarks cannot be read reliably in the browser, and product fill needs a plain background to measure. Look at the image yourself rather than assuming it passes.

Each destination covers one surface: the Amazon main product image, the Google Shopping product feed image, the Walmart Marketplace primary image, and the listing or product photo on eBay, Etsy and Shopify. For additional or variant images, check the marketplace's own page.
