Invisible Watermark.
Tag every image with a hidden, per-subscriber mark for OnlyFans, Fansly & cam content, then detect who leaked it. Survives screenshots, compression, and cropping.
This identifies who receives the content. Max 32 characters.
Invisible watermark
What an invisible watermark does.
An invisible watermark embeds a hidden, per-recipient identifier inside an image — the subscriber's username and the date — woven into the image data itself rather than printed on top. There is no visible logo, badge, or text overlay, so the photo looks identical to the original.
If that image later turns up somewhere it should not, you can run it back through the detector to read out which recipient it was originally sent to. It is forensic information: it tells you who, not how a file got there.
How it works
From send to detection.
- 1
Add the recipient
Enter the username of the subscriber or buyer you are about to send the image to.
- 2
Watermark the image
Upload your photo and the tool embeds a hidden identifier, then download the watermarked copy.
- 3
Send your content
Share the watermarked version through PPV, DMs, or anywhere else. It looks identical to the original.
- 4
Detect a leak
If a copy surfaces, switch to Detect mode and upload it to read back the embedded username and date.
Durability
What the watermark survives.
The identifier is spread across the image's frequency data, so it persists through the everyday transformations a shared file goes through:
- Screenshots and re-photographs of a screen
- JPEG and WebP re-compression and platform re-encoding
- Moderate cropping and resizing
- Re-saving and format conversion
Extreme crops, heavy filters, or AI re-generation can degrade it, which is why the detector also reports a confidence score alongside any match.
Frequently asked questions.
Yes. The identifier is embedded in the image's frequency data, below the threshold of human perception, so the watermarked file looks identical to the original at normal viewing.
Yes. It is designed to persist through screenshots, JPEG and WebP re-compression, moderate cropping, and resizing. Heavy edits can weaken it, which is why detection returns a confidence score.
You can upload JPG, PNG, WebP, and HEIC/HEIF (iPhone) images. The watermarked file is returned as a JPEG for maximum robustness.
Images up to 8 MB are supported.
No. Images are processed in real time to apply or read the watermark and are never stored — nothing you upload is kept after the request completes.
Switch to Detect mode and upload the suspected image. If it was watermarked with this tool, the detector reads back the recipient username and the date it was watermarked.
There is no visible mark to crop out. Because the identifier lives in the image data, it survives ordinary edits; only aggressive transformation degrades it, and the detector flags lower-confidence reads.
No. The watermark and detection tools are free to use right in your browser.
