About ListingLint

A free, private tool that tells you why a product photo would be rejected on Amazon, eBay, or Etsy — before you upload it — plus a library of guides explaining the rule behind every check.

Why it exists

Marketplaces reject product photos for reasons they rarely spell out. A background that looks white to your eye but isn't exactly RGB 255,255,255. An image a few pixels too small for zoom. A product that doesn't fill enough of the frame. A stray watermark or border. The result is a rejected listing, a delayed launch, and no clear explanation of what went wrong.

ListingLint closes that gap. It measures your image against each marketplace's published rules and shows you the exact check that fails — in plain language — so you can fix it in seconds instead of guessing.

How it works

You drop in a photo; ListingLint reads the pixels directly in your browser and runs each rule: dimensions, background colour, how much of the frame the product fills, and heuristics for edge shadows and stray text or borders. Where it can, it fixes problems in one click — snapping a near-white background to pure white, or resizing to the recommended dimensions. Everything happens locally. For a full breakdown of each check and the tolerances we use, see how ListingLint checks your photos, and browse our product photo guides.

Privacy first

Your images never leave your device. There's no upload, no account, and no server that ever sees your photos. That's not a setting you have to turn on — it's how the tool is built. See our privacy policy for the details.

Who runs ListingLint

ListingLint is an independent project maintained by a small group of people who have listed and sold products on Amazon, eBay, and Etsy, and who have spent more time than they'd like re-exporting photos to get past a silent rejection. It is not a marketplace agency, a photo-editing service, or a venture-backed company, and it is not affiliated with, endorsed by, or connected to Amazon, eBay, or Etsy in any way. The name refers to the project, not a company.

We deliberately keep the operation small and the data footprint at zero: the tool has no accounts and no server that receives your images, so there is very little for you to have to trust us with. If you want to reach a person, the contact page has a monitored email address.

How we keep the rules current

Every marketplace ruleset the checker uses carries a "verified" date and a link to the official policy it's based on, both shown in the tool. When we re-confirm a spec against its source, we update that date. Our standing practice:

• Each numeric rule (minimum pixel size, the 85% fill guideline, the pure-white requirement) is taken from the marketplace's own published seller documentation, not from forum lore.
• Where sellers commonly repeat a myth — "Amazon needs 300 DPI" is the classic — we say so explicitly and explain what actually matters.
• Guides are dated and show an "Updated" line. A guide we haven't re-checked in a while is still labelled honestly rather than quietly presented as current.
• If you find a rule that's changed before we do, tell us and we'll correct the page and the ruleset.

None of this makes ListingLint an official source. Marketplace policies change without notice and vary by category, so we always recommend confirming against the marketplace's own help pages before you rely on a result. See how ListingLint checks your photos for the measurement detail behind each check.

How it's funded

ListingLint is free and supported by advertising. We don't sell your data — there is none to sell — and we don't take payment from Amazon, eBay, Etsy, or any editing-software vendor to say anything in particular. Advertising is handled by Google AdSense; how that uses cookies is covered in the cookie policy and privacy policy.
