Confirm your watermark is present — upload your certificate and file
Version 1.0 | Works with certificates from AIWatermark.com
Save This Verifier Alongside Your Certificates
Why: Save this page with your certificates so you always have a verifier ready — even years from now. Images: Can be verified with the saved file alone (no internet needed). Videos: Require an internet connection — verification runs on AIWatermark's GPU server.
What Is This? An independent verification tool that proves you own a watermarked file — using the certificate downloaded from AIWatermark.
How It Works: Upload your certificate.json + your watermarked file. The tool decodes the embedded watermark and checks it matches your certificate. Uses DCT spread-spectrum for images and Meta VideoSeal AI for videos.
Connection Required for Video: VideoSeal detection runs on AIWatermark's GPU server — an internet connection is needed. Image verification can run offline.
Single-File Verification: This tool verifies ONE file at a time (designed for legal/archival purposes). For bulk processing, use multi-file verifier.
