How each method works, and where it stops
Each item below is a protection method Bulk Watermark SGTLab uses, followed by the documented behaviour of that method. These limits are general properties of how web browsers and operating systems work, not faults specific to this app.
Visible watermark or logo overlay
Stamps a logo, text, or sticker onto the product image, so any copy carries a visible mark.
In practice, it can be bypassed:
- A watermark in a corner or along an edge can be removed by cropping the image.
- Generative AI object-removal and inpainting tools, many of them free, reconstruct the area under a mark and erase it in seconds, including semi-transparent marks placed across the whole image.
- The clone and healing tools in any image editor can paint a mark out manually.

The difference that matters: proof
Bulk Watermark SGTLab works to make copying less convenient while a visitor is on your store. None of those methods change what happens after an image is saved, screenshotted, or re-uploaded somewhere else. At that point the copy carries no information that ties it back to you, so there is nothing to present to a host or marketplace that processes a takedown.
Tilkie takes the other side of that problem. It embeds an invisible watermark in the pixels of your image using TrustMark, the neural watermarking engine backed by Adobe. The mark stays readable after cropping, resizing, re-encoding, and screenshots, you can detect a copy anywhere on the web by URL or upload, and a confirmed detection produces a Chain of Proof certificate built for DMCA and marketplace complaints. The image your customers see is unchanged.
