Invisible Watermark Survival Simulator
Answer four questions about format, sharing channel, compression, and screenshot risk to get a method recommendation.
Interactive recommendations for LSB, DCT, TrustMark, Robust Transform, and WAM.
Honest caveats for social platforms, screenshots, and heavy compression.
Recommendations based on Foddo watermark method profiles and known survival caveats.
Invisible watermark methods fail in different places. LSB breaks under heavy JPEG compression, DCT survives some social re-encodes, and screenshot workflows destroy methods that never meant to survive rasterization.
The survival simulator asks four questions about your format, sharing channel, compression, and screenshot risk, then recommends a method with honest caveats. Use it before you commit to a batch workflow that cannot be undone.
Foddo implements multiple methods locally so your delivery path picks the protection that matches how subscribers actually share files, not how you wish they would.

Watermark Survival Simulator
Choose your delivery scenario and get an honest method recommendation before you embed invisible recipient IDs.
Recommended method: Robust Transform
PromisingRobust Transform fits direct delivery with controlled formats and lighter compression risk.
Foddo supports multiple invisible methods locally, including LSB, JPEG DCT, TrustMark, Robust Transform, and WAM. This simulator reflects current method profiles, not guarantees.
Important limits
- Screenshots create a new bitmap and can destroy pixel-level invisible marks.
- Inspect the exact downloaded copy when investigating a leak, not a repost preview.

Workflow Upgrade
Move from one-off checks to repeatable protected delivery
Different invisible methods survive different edits. Foddo implements multiple methods locally so you can match protection to your real delivery path.
