Almost every seller who has been copied once asks the same question: should I put my logo on my product photos? You spent a weekend shooting, editing and cutting out backgrounds, and within a month a competitor is running your exact hero shot on their listing. A watermark feels like the obvious defence.
The problem is that the marketplaces you sell on mostly disagree. In 2026, watermarks are explicitly banned on main product images across Amazon, eBay and Google Shopping, and they are restricted almost everywhere else. Adding one to protect your work can quietly get your listing suppressed, your ads disapproved or your images silently replaced. This guide covers what each platform actually allows, why watermarks rarely stop theft anyway, and what to do instead.
The short answer
Do not watermark the main image of any marketplace listing. Keep watermarks for channels you control, such as your own website, social posts, wholesale line sheets and preview images you send to partners. On marketplaces, protect your work through reporting mechanisms and distinctive styling rather than an overlay that breaks the listing rules.
What each platform actually allows
Policies differ enough that a single watermarked master file will pass on some channels and fail on others. Here is the current position on the platforms most sellers use.
| Platform | Watermark on main image | Notes |
|---|---|---|
| Amazon | Not allowed | No text, logos, watermarks or promotional overlays on the main image. A logo printed on the actual product or its packaging is fine. Text and graphics are permitted on secondary images only. |
| eBay | Effectively not allowed | Promotional text, added borders and branding overlays breach the images and text policy. A minimal seller identifier or copyright line at low opacity is the only tolerated exception. Automated detection can suppress, replace or reject offending photos. |
| Google Shopping / Merchant Center | Not allowed | Watermarks, promotional overlays such as "SALE" or price badges, and decorative borders all trigger disapproval. Image problems account for a large share of all Merchant Center rejections. |
| Shopee | Own branding tolerated | Seller watermarks are commonly applied to the first main image. Using images that carry someone else's watermark or branding without permission is a violation. |
| Lazada | Own branding tolerated | Watermarks apply to the main and variant images. Watermark files must be PNG with a transparent or white background. |
| Shopify (your own store) | Your choice | No platform rule, but the same images usually feed Google Shopping and Meta catalogues, where watermarks are rejected. |
| Carousell | Tolerated | Common among resellers to deter listing scrapers, though it still costs you clarity on small thumbnails. |
The catch is the last column of your workflow, not the first. Even if Shopee and Lazada tolerate your logo, the same photo set usually also feeds Google Shopping, Meta catalogue ads and Amazon. One watermarked master file means either maintaining two versions or accepting rejections on the channels that matter most for paid traffic.
The automated removal trap
Google Merchant Center now offers automatic image improvements, which attempt to detect and strip text, watermarks, overlays and logos so the product can be approved. That sounds helpful, but it means an algorithm is editing your hero image without your review. Removal artefacts, softened edges and smeared patches where the logo used to sit are common. You lose control of the very asset you were trying to protect.
Why watermarks rarely stop image theft
The uncomfortable truth is that a watermark stops a lazy copier and nobody else.
- Cropping. A corner watermark is removed with one crop. Since most marketplaces display square thumbnails, a copier can crop 10 per cent off an edge and still have a compliant image.
- Content-aware removal. Free tools now erase a semi-transparent logo from a flat white background in seconds. White-background product photography is the easiest possible case for these tools.
- Re-shooting the layout. If your competitor sells the identical item from the same supplier, they can copy your angle, prop and crop without touching your file at all.
- Overlaying. Some copiers simply place their own mark on top of yours, which is a well-documented pattern on marketplace listings.
Meanwhile the watermark is visible to every genuine shopper, on every impression, forever. You are paying a permanent conversion cost to slow down a copier for about thirty seconds.
The hidden cost to conversions
There is no reliable public study isolating watermarks specifically, so treat claims of an exact percentage drop with suspicion. What is well evidenced is that image clarity drives purchase decisions: roughly nine in ten shoppers rate photo quality as extremely or very important to their buying decision, and listings with professional-standard photography convert materially better than those with poor images.
A watermark works against that in three concrete ways. It reduces the clean product area within the frame, which matters when marketplaces already require the product to fill 75 to 85 per cent of the image. It becomes visual noise at thumbnail size, where a search result may render at 200 pixels or less and your logo is an unreadable grey smudge across the product. And on marketplaces, a heavy watermark reads as defensive rather than professional, because the platforms shoppers trust most simply do not show them.
When a watermark genuinely makes sense
There are legitimate cases, and they share one trait: the image is not a marketplace main image.
- Wholesale line sheets and B2B catalogues sent to buyers who may forward them onward.
- Preview or proof images shared with clients before payment, particularly for custom and made-to-order work.
- Social content, where a small, tasteful brand mark travels with reposts and builds recognition.
- Lifestyle and editorial shots on your own site, where the photograph itself is the valuable asset rather than a spec-compliant product cut-out.
- Original artwork and digital products, where the image is effectively the product and a preview must be degraded deliberately.
Better ways to protect your images
Build a visual signature instead
The strongest protection is making your photos obviously yours without altering the pixels a shopper looks at. A consistent background tone, a repeated prop, a signature lighting direction and a fixed set of angles across the catalogue create a recognisable house style. When a competitor lifts one of those images, it looks out of place next to their other listings, and it is immediately identifiable to you and to the platform's IP team.
Use the reporting routes that actually work
Every major marketplace has an intellectual property complaint process, and photographs you took are your copyright by default. Keep the original camera files with their EXIF data intact as proof of authorship, note the capture dates, and file a report with the offending listing URL. This removes the copy permanently, which no watermark ever does.
Embed copyright in the metadata
Add your name and a copyright notice to the IPTC and EXIF fields of your masters. It is invisible to shoppers, survives most transfers, and provides supporting evidence in a dispute. Be aware that many platforms strip metadata on upload, so keep your local masters as the authoritative record.
Run periodic reverse image searches
Once a month, run your top ten hero images through a reverse image search and check the marketplaces you compete on. Detection matters more than deterrence, because the takedown is the part that sticks.
If you do watermark, do it properly
For the channels where it is appropriate, a few rules keep the damage minimal:
- Always keep an unwatermarked master. Archive clean originals at full resolution. Every marketplace, ad platform and catalogue feed will need them eventually.
- Watermark last, after resizing. If you apply the mark before resizing to each platform's dimensions, it scales unpredictably and can end up illegible on small formats or oversized on large ones. Resize first, then overlay, so the mark stays proportionate.
- Keep it under 10 per cent of the frame and set opacity around 20 to 30 per cent.
- Place it in a corner over background, never across the product, so the item itself stays fully readable.
- Use PNG with a transparent background if the platform applies the watermark for you, as Lazada requires.
The workflow that causes the least pain is keeping clean masters as the single source of truth and generating each channel's sized version from them. If you are producing Amazon, Shopee, Lazada and Google Shopping versions of the same shoot, a batch tool such as PixelPrep handles the per-marketplace dimensions in one pass, so the compliant unwatermarked set is the easy default rather than an extra chore.
Your watermark checklist
- No watermark, logo or text on any marketplace main image.
- Check whether your marketplace images also feed Google Shopping or Meta catalogues before adding any overlay.
- Store clean, full-resolution masters with EXIF and IPTC copyright intact.
- Reserve watermarks for line sheets, client proofs, social posts and digital-product previews.
- If watermarking, apply it after resizing, at 20 to 30 per cent opacity, under 10 per cent of the frame, off the product.
- Build a recognisable house style so your photos are identifiable without an overlay.
- Reverse image search your hero shots monthly and file IP complaints on copies.
Protecting your photography is a real concern, but the overlay is the weakest tool available. Clean images sell better, pass every platform check, and leave you free to enforce your rights through the channels that actually get a copy taken down.
