How to Use the Watermark Tool.

The Watermark Tool lets you add invisible watermarks to your OnlyFans and Fansly content. When an image gets leaked, you can identify exactly who shared it. The watermark survives screenshots, compression, and cropping.

Part 1: Adding Watermarks

Go to leakless.io/watermark and make sure the Watermark tab is selected.

1. Enter the receiver's username (the person you're sending the content to)
2. Upload your image (JPG, PNG, WebP, or HEIC - max 8MB)

1. Click Download Watermarked Image

The watermark is invisible—your image looks exactly the same, but now contains hidden data identifying the receiver.

Part 2: Detecting Leakers

Found your content leaked somewhere? Upload it to find out who shared it.

1. Switch to the Detect Leak tab
2. Upload the suspected leaked image

1. See who leaked it, when it was watermarked, and confidence level

Tips for Best Results

• Watermark each image with the specific recipient's username before sending
• Detection only works on images watermarked with this tool
• The watermark survives screenshots, compression, and cropping
