Invisible forensic watermarking that survives anything
Neural watermarking API plus C2PA signing. Protect and trace your images across crop, compression, screenshots, and social media re-encoding. For AI pipelines, content creators, and media teams. Free to try.

Cropped - still detected
Modified - still detected
Forever tier
Everything you need for image provenance
One API. Two layers of protection. Works for AI pipelines, content creators, and enterprise compliance.
Neural Robustness
Survives crop, rotation, screenshot, JPEG compression, resize, and social media re-encoding. Tested against Instagram and Twitter. Where classic DWT and DCT watermarks silently fail, ForensicMark holds.
Invisible + C2PA Combined
The only API offering both pixel-level provenance and a cryptographic C2PA manifest in one call. C2PA covers file integrity; the invisible watermark survives re-encodes and screenshots.
MCP Native
AI agents can watermark images via a tool call. MCP server available for Claude, Cursor, and any MCP-compatible workflow. Zero-friction adoption in agentic pipelines.
Developer First
REST API, clean docs, free demo tier with no signup. One endpoint, two layers of provenance. Upgrade to an API key via contact form - no sales call required.
EU AI Act Ready
Article 50 requires machine-readable markings on AI-generated content by August 2026. ForensicMark satisfies the requirement using watermarks and C2PA as explicitly listed compliance methods.
Free Tier Always
20 invisible watermark embeds per day, 15 C2PA signs, 30 detections, 30 C2PA verifications. No account. No credit card. Upgrade when you need batch processing or API key access.

From AI image pipelines to creative agencies
"We watermark every image our platform generates. Three lines of code, and our compliance team stopped asking questions after we showed them the detection demo working on a screenshotted image."
Alex Turner
Lead Engineer at ImageFlow
"We protect hundreds of client photos before publishing. If anything gets taken, we can trace exactly where it came from. CopyrightShark handles the takedowns after that. The combo is powerful."
Sofia Marchetti
Photo Editor at Novo Agency
"The robustness benchmark sold us. We tested it ourselves - cropped, compressed, screenshotted, ran it through Instagram. The watermark came back every time. No other vendor could show us that."
David Kim
Security Lead at MediaStack
Detect leaks. File takedowns.
ForensicMark traces every leaked image back to its source. CopyrightShark handles the DMCA takedowns.
Watermark per recipient
Embed a unique payload per user, client, or distribution channel. When the same image appears somewhere it shouldn't, the payload identifies exactly who it came from.
Detect the source
Run the leaked image through ForensicMark's detection endpoint. The watermark survives crop, screenshot, compression, and re-encoding — you get the original payload back.
File the takedown
Hand the forensic evidence to CopyrightShark. They handle DMCA notices, platform removal requests, and legal escalation so you don't have to.
