A seller downloads your product photo, crops out the corner watermark, and lists the counterfeit with your image. Your watermark did nothing, because it was placed where a crop removes it. That is the most common watermarking mistake, and it is a placement mistake, not a watermarking mistake. A watermark that survives is one placed where removal damages the image itself, and that is a design decision you make before the photo ever goes live.

The point of a watermark is not to make the photo unusable. It is to make the theft provable. A counterfeit listing carrying your watermarked photo is a copyright case with the evidence built into the listing, and that case moves faster than any trademark complaint.

## Where to put it

The center of the image, across the product itself, light enough that a buyer can still see what they are buying. A watermark in a corner or along an edge is a decoration. A watermark across the middle forces the thief to choose between cropping out the product and leaving the mark in. Most of them leave the mark in, because the crop that removes it also removes the part of the photo that sells the item.

Tiling is the stronger version: a small, semi-transparent mark repeated across the image at low opacity. It survives cropping because there is no single corner to cut, and it survives compression because the pattern repeats. Keep the opacity low, around 10 to 15 percent, so it reads as texture rather than an obstruction. A watermark that ruins the photo hurts your sales more than it hurts the thief.

## What survives compression and re-upload

Marketplace uploads compress images, and compression is the second killer of watermarks. Thin lines and small text blur into nothing at the compression levels a marketplace applies. Bold, simple marks survive: a short brand name in a heavy weight, or a simple logo shape, rather than a fine script. Test it the way a thief would: upload the watermarked photo to the marketplace, download it back, and look at what is left. If your own download does not show the mark clearly, no reviewer will see it either.

Color matters too. A white watermark on a white background vanishes. A dark mark on a dark product vanishes. Use a mark with an outline or a shadow so it stays visible against any background, and place it where the product's own tones are most consistent, so the contrast holds across the image.

## The watermark is evidence, not the case

A surviving watermark proves the photo is yours, but the takedown still needs a filing. Keep the original files, RAW or earliest dated export, because the original is what you produce if the seller files a counter-notice. The watermark in the listing plus the original file in your records is the complete evidence pack: the listing shows the theft, the file shows the ownership.

And do not rely on watermarking alone. Monitor for your images with reverse image search, not just your brand name, because image search catches listings that text search misses. The watermark makes the stolen photo provable. The monitoring is what finds it. A provable theft that nobody notices is still a listing selling your product.

## Frequently asked questions

### Where should a watermark go on a product photo?

Across the center of the image, over the product itself, at low opacity. A corner watermark gets cropped out in seconds. A center mark forces the thief to choose between removing the product and leaving the mark.

### What opacity should a watermark be?

Around 10 to 15 percent, as a repeated tile or a single center mark. Low enough to read as texture and not obstruct the sale, high enough to survive marketplace compression.

### Does watermarking stop photo theft?

No. It makes the theft provable. A counterfeit listing carrying your watermarked photo is a copyright case with the evidence built in, and that case moves faster than a trademark complaint about the product.

### What else do I need besides the watermark for a takedown?

The original file, RAW or earliest dated export, to prove ownership if the seller files a counter-notice. And monitoring: reverse image search finds listings that text search misses.
