Gemini watermark remover

Gemini Watermark Remover for Nano Banana images.

Images from Gemini and Nano Banana carry two watermarks: the visible four-point sparkle in the corner and Google’s invisible SynthID signal in the pixels. We handle both. See the Nano Banana specifics or read removing the Gemini / Nano Banana watermark.

How it works

Upload. We clear both marks. You download.

The visible sparkle and the invisible signal, in one private pass.

01

Upload a supported image

Sign in and add your Gemini or Nano Banana image in JPEG, PNG, WebP, AVIF, HEIC, or HEIF, up to 20 MB.

02

We process it privately

We reconstruct the corner where the sparkle sits, strip supported metadata, and regenerate pixels to disrupt SynthID.

What it removes

Both Gemini watermarks, not just the visible one.

Painting out the sparkle makes an image look unmarked while the invisible SynthID signal stays put. A real Gemini watermark remover has to address both.

Visible

The corner sparkle

The four-point star Gemini adds bottom-right is located and the surrounding image detail is reconstructed so the patch blends into the scene.

Embedded

The SynthID signal

Local diffusion / SDXL regeneration disrupts the imperceptible SynthID pattern in the pixels. The detector is proprietary, so removal is not guaranteed.

Metadata

Provenance fields

Strips supported EXIF, XMP, and C2PA Content Credentials that identify the file as generated by a Google model.

Gemini and Nano Banana

What Google marks, and how we clear it.

The visible sparkle

Gemini 2.5 Flash Image (“Nano Banana”) stamps a small semi-transparent four-point star in the bottom-right corner. It is 48×48px on standard images and 96×96px above roughly 1024px. Because it sits in a known region, it can be removed by reconstructing the texture underneath, as covered in removing a visible AI watermark and the Nano Banana page.

The invisible SynthID layer

Beyond the sparkle, Gemini and Nano Banana images carry Google DeepMind’s SynthID watermark embedded imperceptibly in the pixels and frequency domain. It survives cropping and compression, so clearing the visible star alone leaves the invisible signal intact. Disrupting it takes local regeneration. See what SynthID is.

Why both matter together

If you only remove the sparkle, a detector can still flag SynthID; if you only regenerate pixels, the visible star may still be there. Handling both in one pass is the point of a dedicated AI watermark remover. Verify results with Google’s SynthID Detector and at contentcredentials.org/verify.

Formats and verification

We accept JPEG, PNG, WebP, AVIF, HEIC, and HEIF up to 20 MB. Choosing the right output format helps preserve quality. See the format guide. Processing runs privately and in isolation, as described in private, offline processing.

Straight answers

Gemini and Nano Banana watermarks, answered.

How do I remove the Gemini watermark?

Upload your Gemini or Nano Banana image and we reconstruct the corner where the sparkle sits, strip supported metadata, and regenerate pixels to disrupt the embedded SynthID signal. The first image is free.

Where is the Nano Banana watermark located?

The visible sparkle is a small semi-transparent four-point star in the bottom-right corner, 48×48px on standard images and 96×96px above about 1024px. An invisible SynthID signal is also spread across the whole frame.

Does cropping the corner remove the Gemini watermark?

It can remove the visible sparkle, but the invisible SynthID watermark is distributed across the image, so cropping does not reliably clear it. That is why we regenerate pixels rather than just trim the corner.

Is this affiliated with Google or Gemini?

No. Delete SynthID is an independent service and is not affiliated with, endorsed by, or operated by Google.

What does it cost?

Your first image is free. After that you buy one-time credits with no subscription, and the per-image rate drops as pack size grows.

For your own Gemini images.

Use this only on Gemini or Nano Banana images you created or have the right to edit. Results vary by image and watermark version, and no tool guarantees the SynthID signal is gone. Delete SynthID is not affiliated with or endorsed by Google. See responsible editing.
