Listing Image Checker: Test a Photo and Fix It in One Tab
Drop a product photo, pick Etsy, eBay, Amazon or Shopify, and get a pass or fail on the exact numbers that marketplace enforces — shortest side, file size, background. When it fails on something a file can be fixed for, hit Fix and download a copy that passes. Same tab, nothing uploaded.
The numbers each marketplace actually enforces
These are the published seller rules as of 2026, not general advice. A photo that passes all four columns will upload; a photo that fails one usually uploads anyway and then gets suppressed later.
| Platform | Minimum | Recommended | Max file | Background |
|---|---|---|---|---|
| Etsy | 635 px first photo | 2000 × 2000 | under 1 MB | Any — transparent PNG renders black |
| eBay | 500 px | 1600 × 1600 | 12 MB | White or neutral, no watermarks |
| Amazon | 1000 px for zoom | 2000 × 2000 | 10 MB | Pure #FFFFFF, product fills 85% |
| Shopify | 800 px | 2048 × 2048 | 20 MB | Theme dependent, usually square |
What a listing image checker actually measures
Marketplace rules are not about how good a photo looks. They are three hard numbers: the shortest side in pixels, the file size in bytes, and — for Amazon only — the background colour. A photo can be sharp, well lit and still get suppressed because it is 800 px wide or 1.4 MB.
This checker reads all three from the actual file. It does not guess from the filename or the camera metadata, because pixels and bytes are the only things the platform measures.
Why listings fail after they look fine
The failure is usually silent. The photo uploads, the listing goes live, and then it simply does not appear in search — or the upload bar stalls at 90% with no error message. Etsy’s seller help page is explicit that photos over 1 MB may not finish uploading, which is why a 2000 px photo straight off a camera can fail on size alone.
Checking before you upload takes a few seconds and removes that entire failure mode. It also tells you which number to fix, so you do not shrink a photo that only needed a lower JPEG quality.
Diagnose and fix in one place, not two
Search this term and you will find a dozen tools, several of them covering more marketplaces than this one does. Nearly all of them stop at the verdict: you get a red row, then a link to a resizer or a compressor somewhere else — often a different site, which uploads your photo to a server to do the work.
The time goes in the gap between “your photo is 1.4 MB” and “here is the 780 KB copy that passes”. This checker closes that gap in the same view: the shortest side is padded up to the platform minimum without cropping, then the file is re-encoded to land under the byte ceiling while keeping the pixels the platform actually measures.
Two failures have no file-level fix, and the checker says so instead of handing you a file that will fail anyway: a background that is not pure #FFFFFF has to be reshot or cut out, and a photo below the minimum pixel size has no detail to recover.
Which platform to check against
If you sell on several platforms, run the strictest one first. Amazon MAIN rules are the tightest — pure white background, 1000 px minimum for zoom, 10 MB — and a photo that passes them also passes eBay and Etsy. The reverse is not true.
If you sell on one platform only, check against that one. eBay is the most forgiving on file size and the strictest on watermarks; Etsy is the one where file size, not pixels, is the usual culprit.
Rules for the platform you sell on
How it works
- Drop a product photo. Your browser reads it locally — nothing is sent anywhere.
- Pick the marketplace you are uploading to, so the right limits are applied.
- Read the verdict, hit Fix on a size problem, and download a file that passes.
Why running locally matters for a seller
Most online converters upload your file to a server, process it, and hand back a link. For a stock photo that is fine. For a supplier catalogue under NDA, an unreleased product, or a client shoot, you have just handed your images to a stranger with an unknown retention policy.
Because the work happens in the tab, a twenty-photo batch is limited by your laptop rather than your upload speed, and it keeps working when the connection drops. There is no queue, no account, and no copy on someone else’s disk.
Questions
Are my photos uploaded to a server?
No. Every tool here decodes and re-encodes images inside your browser using Canvas. There is no upload step, no storage bucket and no retention window — close the tab and nothing remains.
What size should a listing photo be?
Etsy recommends 2000 × 2000 px and warns that files over 1 MB may not finish uploading. eBay wants 500 px minimum and about 1600 × 1600 px recommended, with a 12 MB ceiling. Amazon needs 1000 px minimum for zoom, recommends 2000 × 2000 px, and requires a pure white background under 10 MB.
Why was my product photo rejected?
Most rejections come from four things: a background that is not exactly #FFFFFF (Amazon only), a file larger than the platform limit, a shortest side below the minimum, or a content rule — text, watermarks, props, or a photo that does not show the actual item. This site checks the first three; the fourth needs your judgement.
Is it free?
Yes, for up to 3 files per batch. Pro is a one-time $19 purchase that raises the limit to 50 files per batch. No subscription and no account.
Do I need an account?
No. Nothing here requires a login, an email address or a card. Pro is unlocked with a code you receive once.
Does it work on a phone?
Yes, in any current mobile browser. Large batches are faster on a laptop, but checking and fixing a single iPhone HEIC photo works fine on the phone it was shot on.
Need bigger batches?
The free tier handles 3 files per batch. Pro is a one-time USD 19 purchase that raises the limit to 50 files and 50 MB per file — no subscription, because nobody wants another monthly bill for a tool they use twice a month. See pricing.
