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.
Each recommendation names the edits it will not survive.
Invisible watermark methods fail in different places. LSB breaks under heavy JPEG compression, DCT survives some social re-encodes, and screenshots destroy methods that were never designed to survive them.
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.
