Google adds a toggle in Gemini and Flow to remove visible watermarks from AI-generated images, videos, and music; SynthID watermarks and C2PA metadata remain

Google will still embed invisible SynthID and C2PA watermarks into AI-generated images, videos, and music.

The Verge 2026-08-15 Emma Roth

Context & Ripple Effects

Google introduced SynthID’s invisible image watermarking as a provenance layer for Imagen-made images, then extended the system to generated text. The new control separates that machine-readable layer from the visible signal users see in Gemini and Flow.

The decision also lands after OpenAI added support for SynthID in AI images, giving Google’s retained invisible watermark a broader interoperability rationale even as it makes outward labeling optional.

First-order effects

Gemini and Flow users can deliver AI-generated images, video, and music without a visible watermark, while Google continues to attach SynthID and C2PA provenance data to the media.
Google shifts disclosure in its own creation tools from a mandatory on-media marker to metadata and an invisible watermark that requires compatible detection tools.

Second-order effects

OpenAI’s SynthID support makes cross-provider detection more valuable: services that inspect provenance can still identify Google-generated media after the visible marker is removed.
Publishers and platforms relying on conspicuous labels must instead use C2PA or SynthID-aware verification workflows when reviewing Gemini- and Flow-generated assets.

Third-order effects

AI provenance is separating into a presentation layer chosen by creators and a verification layer read by tools, concentrating practical disclosure power in the platforms that control detection and distribution.
If other model providers follow Google and OpenAI’s interoperability path, synthetic-media labeling will depend less on persistent visible badges and more on shared provenance standards.

The trend: Synthetic-media providers are moving from always-visible AI labels toward interoperable, machine-readable provenance that can persist across creative workflows.

Rolling out over the next few days, you can decide if your image, video, and music creations made with Gemini will have visible watermarks. Invisible SynthID watermarks and C2PA metadata will always stay embedded in the background. Simply go to your settings and toggle “Show

✅ Papercut fixed: You can now toggle visible watermarks on or off in Gemini and Flow, with Search coming next. This applies to watermarks on all images (Nano Banana), videos (Omni), and songs (Lyria) except in countries where it's required by law to keep them.

We're striking a balance here between creative control and safety: while the visible watermarks are now optional, invisible SynthID watermarks and C2PA metadata are still being used for transparency. So you can still use Gemini or Search to see if an image was AI-generated.

We're also open-sourcing Credentio, a new C++ library for C2PA Content Credentials to help developers build better provenance tools. Check it out: https://developers.googleblog.com/ ...

Fakers will fake. They will see watermarks, or rather the lack of them, as an opportunity make their fakes seem genuine. www.bleepingcomputer.com/news/ securit...
