How It Works
Learn about invisible watermarks and how they protect your images.
What is an invisible watermark?
An invisible watermark is a unique identifier embedded directly into your image's pixels. Unlike visible watermarks that cover your work with text or logos, invisible watermarks are completely imperceptible to viewers.
Think of it like a hidden signature that only special tools can detect.
Visible watermark - Distracting and unprofessional
Invisible watermark - Same protection, no visible mark
How does it work?
Protecting your image takes just three simple steps:
Upload
Upload any image from your device. Your image is sent to our secure processing server, watermarked in seconds, and returned. We never save it to disk.
Watermark
We embed a unique Watermark ID into your image using advanced signal processing. This ID is invisible to the eye but can be detected by our verification tools.
Share
Download your watermarked image and share it anywhere. The watermark survives screenshots, compression, cropping, and social media uploads.
What does the watermark survive?
Our watermarks are designed to be resilient against common image transformations:
Note: Heavy editing, extreme cropping, or re-photographing a screen may damage the watermark.
How does verification work?
Anyone can verify a watermarked image. No account required.
- 1
Go to the Verify page
- 2
Upload the image
- 3
We detect the Watermark ID (if present)
- 4
We show you when the image was watermarked and any public details the owner has shared
Is my image safe?
Yes. We take your privacy seriously.
Images are never stored
Your image is sent to our secure processing server, watermarked in seconds, and returned. We never save it to disk. It exists in memory only during the few seconds of processing.
Minimal data collection
We store only the Watermark ID and your registration record. Your image content is never retained, and we do not use your images to train AI models.
Your identity is hidden by default
Only you can choose to reveal who you are.
You don't need to share your original
Others can verify a watermarked copy without you sending them anything. Your original stays private.
