How each method works, and where it stops
Each item below is a protection method SuprImg: Anti-theft Watermark 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.
Right-click (context menu) blocking
Runs a script that cancels the browser's right-click menu so the Save image as option does not appear.
In practice, it can be bypassed:
- The image has already been downloaded to the visitor's device in order to display it, so it can be saved without the menu.
- In Firefox, holding Shift while right-clicking bypasses a site's attempt to block the context menu.
- Turning off JavaScript, or opening the page in reader mode, removes the block entirely.
- The image file can be opened directly from the page source or the browser's developer tools.
Copy, paste, and text-selection blocking
Disables selecting, copying, and pasting text on the page with a script.
In practice, it can be bypassed:
- Viewing the page source (Ctrl+U) or the developer tools shows the full text, which can be copied directly.
- Turning off JavaScript restores normal selection and copying.
- Reader mode and Save page as extract the text regardless.
- Search engines and translation tools read the raw HTML, so the text is never actually hidden.
Developer-tools and inspect-element blocking
Tries to detect or prevent opening the browser developer tools and viewing the page source.
In practice, it can be bypassed:
- Developer tools can be opened from the browser menu, before the page loads, or with shortcuts the script does not catch.
- Adding view-source: before the URL, or choosing View source from the browser menu, is unaffected.
- The browser developer tools list every image and file the page has loaded under the Network and Sources panels.
- Turning off JavaScript disables the blocker itself.

The difference that matters: proof
SuprImg: Anti-theft Watermark 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.
