Quoted passage AI-generated image and video

SynthID adds an invisible digital watermark to an AI-generated image (or video segment). The watermark doesn’t change the image or video quality. It’s added the moment content is created, and designed to stand up to modifications like cropping, adding filters, changing frame rates, or lossy compression.

Limits and detection

Checking tool from the makerA way the maker offers to check a file for its traces.

Google says people can upload an image, video or audio clip to Gemini and ask whether Google AI created or altered it, and that Gemini, Search and Chrome will check for a SynthID watermark; Gemini recognizes SynthID only in content from Google AI tools. Google began rolling out Content Credentials verification in the Gemini app on May 19, 2026, saying it would come to Search and Chrome in the coming months; Gemini Apps Help says it is available on the web and Android, with iOS coming.

Gemini shows the company that signed a file's Content Credentials, supports version 2.2 and later from products on the C2PA Conforming Products List, and does not read remotely stored metadata.

Quoted passage Detecting Google SynthID watermarks in Gemini, Search and Chrome

Simply upload the image, video or audio clip to your chat, and ask if it’s been created or altered by Google AI. Gemini, Search and Chrome will check for a SynthID watermark, and let you know if it finds one.

Verify AI-generated images, videos, and audioGoogle (Gemini Apps Help)

Quoted passage Introduction

There are two technologies used to check for AI-generated content in Gemini Apps: SynthID: Uses invisible watermarks to determine if images, videos, and audio were generated or edited specifically by Google's AI models. Content Credentials: A technology that acts like a digital passport, documenting the digital content's origin and history, and is used for both AI and non-AI content. Important: Verification with Content Credentials is available at gemini.google.com and in the Gemini app for Android. It will be available in the Gemini app for iOS soon.

Show the company that provided and cryptographically signed the information. For example, “Info by Google LLC” shows that Google provided the information." "Incompatible or unsupported: Gemini Apps supports Content Credentials versions 2.2 and later, from products on the C2PA Conforming Products List . Credentials from products outside that list may not be considered valid or trusted. Additionally, some third-party Content Credentials apps store the metadata remotely, separate from the image, video, or audio file; Gemini Apps don’t support remote metadata.

Making it easier to understand how content was created and editedGoogle (The Keyword blog)

Quoted passage Body, verification paragraphs

We’re also adding verification for C2PA Content Credentials, to easily check if content is an unaltered original from a camera or if it has been modified, and by what tools. This feature is rolling out in the Gemini app starting today, and it will come to Search and Chrome in the coming months.

What the maker says about limitsIn the maker's own words.

Gemini Apps Help says a SynthID result can be unclear for very simple content or very small edits, and that the watermark usually survives re-scaling, re-coloring and compression but may not be detected after many alterations.

Verify AI-generated images, videos, and audioGoogle (Gemini Apps Help)

Quoted passage For SynthID; Common questions about SynthID

In some cases it isn’t clear if the image or video was created or edited by Google AI or not. Some common reasons for this are: "Not enough details to watermark" (e.g., very simple or abstract content). "Likely too small an edit" (minor alterations might not carry a detectable watermark)." "Yes. The digital watermark will usually still exist even if the image, video, or audio is re-scaled, re-colored, compressed or altered in other ways. However, there's still a chance that after many alterations the watermark won’t be detected.

What the maker says about limitsIn the maker's own words.

In May 2024 Google DeepMind said SynthID text watermarking holds up to mild edits, but its confidence can drop greatly when text is thoroughly rewritten or translated, and it is less effective on factual responses.

Quoted passage SynthID for text

It performs well even under some transformations, such as cropping pieces of text, modifying a few words and mild paraphrasing. However, its confidence scores can be greatly reduced when an AI-generated text is thoroughly rewritten or translated to another language." "SynthID text watermarking is less effective on responses to factual prompts because there are fewer opportunities to adjust the token distribution without affecting the factual accuracy.
