What Is the Gemini AI Watermark?

The Gemini AI watermark is a visible four-pointed star icon that Google automatically embeds in all images generated by Google Gemini. This sparkle-shaped marker appears in the bottom-right corner of every AI-created image, serving as a visual indicator of AI-generated content.

Google introduced this watermark to promote transparency and help users identify AI-generated images. If you need to remove it, use our free Gemini watermark remover which uses Smart Brush selection and Biharmonic Inpainting for seamless results.

What Does the Gemini Watermark Look Like?

The Gemini watermark has distinct visual characteristics:

FeatureDescription
ShapeFour-pointed star (sparkle)
ColorWhite or semi-transparent gray
PositionBottom-right corner
Size40-60 pixels approximately
OpacitySemi-transparent

The design matches Google's AI branding, using the same sparkle icon found across their AI products including Bard, Gemini app, and Google Search AI features.

Why Does Google Add a Watermark to Gemini Images?

Google adds the watermark for several important reasons:

1. Transparency and Trust

The watermark immediately identifies images as AI-generated, helping viewers understand they are not looking at real photographs. This supports informed decision-making about content authenticity.

2. Misinformation Prevention

By marking AI images, Google aims to reduce the spread of misleading content. The visible watermark makes it harder to pass off AI creations as genuine photos.

3. Regulatory Compliance

New laws like the California AI Transparency Act (effective 2026) require AI content disclosure. Google's watermark system prepares for these regulations.

4. Industry Standards

Google, along with other AI companies, is establishing norms for responsible AI content labeling. The watermark demonstrates their commitment to ethical AI practices.

How Is the Gemini Watermark Different from SynthID?

Google uses two distinct watermarking technologies:

AspectVisible WatermarkSynthID
VisibilityVisible star iconCompletely invisible
LocationBottom-right cornerEmbedded in pixels
RemovableYes, via Smart Brush + Biharmonic InpaintingNo
Survives croppingNoYes
Survives compressionPartiallyYes
Survives filteringNoYes
Who detects itHumansGoogle's algorithms

The visible watermark is what you see and can remove with our tool. SynthID is Google DeepMind's invisible watermarking technology that embeds information directly into the image's pixel data.

Where Does the Gemini Watermark Appear?

The watermark appears on all images generated through:

PlatformDescription
Gemini AppMobile and web versions
Gemini in Google MessagesAI image generation in chat
Gemini APIDeveloper integrations
Google WorkspaceGemini features in Docs and Slides
ImageFX by GoogleGoogle's dedicated image generator

All Gemini versions include the same watermark placement. Check our complete guide to removing Gemini watermarks for step-by-step instructions using Smart Brush and Biharmonic Inpainting.

Can You Detect If an Image Has the Gemini Watermark?

Yes, detection is straightforward:

Visual Check

Look at the bottom-right corner for the four-pointed star. The watermark is designed to be noticeable while not overly distracting.

Using Gemini Itself

You can upload an image to Gemini and ask "Was this image created with Google AI?" Gemini checks for both the visible watermark and SynthID markers.

Metadata Check

Gemini images may contain metadata indicating AI generation, though this can be stripped during sharing.

Does the Watermark Affect Image Quality?

The watermark has minimal impact on overall image quality:

FactorImpact
Overlay onlyThe star is placed on top of the image
Small areaOnly affects approximately 2-3% of the image
No compressionThe watermark does not degrade the underlying image
RemovableSmart Brush selection + Biharmonic Inpainting eliminates it without quality loss

What Happens If You Screenshot a Gemini Image?

Screenshots preserve the visible watermark but may lose metadata:

ElementWhat Happens
WatermarkRemains visible in screenshots
SynthIDSurvives in the pixel data
MetadataLost during screenshot
QualityMay be reduced through compression

For best quality, download images directly rather than screenshotting.

Are Other AI Image Generators Using Similar Watermarks?

Different AI services handle watermarking differently:

GeneratorVisible WatermarkInvisible Watermark
Google GeminiYes (star icon)Yes (SynthID)
DALL-E 3NoYes (C2PA metadata)
MidjourneyNoNo (but detectable)
Stable DiffusionOptionalNo
Adobe FireflyNoYes (Content Credentials)

Google is among the most visible in their watermarking approach. See our comparison of AI watermark systems for more details.

Frequently Asked Questions

Can the Gemini watermark be turned off?

No. Google does not provide an option to generate images without the watermark. It is automatically applied to all AI-generated images.

Does the watermark appear on edited images?

If you use Gemini to edit an existing photo, the watermark may appear on the edited version, indicating AI involvement in the final result.

Is the watermark copyrighted?

The watermark design belongs to Google, but its presence on your generated images does not affect your usage rights for the underlying content.

Will Google change the watermark in the future?

Google may update the watermark design, but they are committed to maintaining AI content identification. Any changes would likely be communicated in advance.

Conclusion

The Gemini AI watermark serves as Google's visible commitment to AI transparency. While it identifies AI-generated content, you can remove it using our Smart Brush selection and Biharmonic Inpainting technology for personal use when needed. Understanding the difference between this visible marker and SynthID's invisible watermark helps you make informed decisions about AI image usage.
