Sign in and add your Gemini or Nano Banana image in JPEG, PNG, WebP, AVIF, HEIC, or HEIF, up to 20 MB.
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.
The visible sparkle and the invisible signal, in one private pass.
Sign in and add your Gemini or Nano Banana image in JPEG, PNG, WebP, AVIF, HEIC, or HEIF, up to 20 MB.
We reconstruct the corner where the sparkle sits, strip supported metadata, and regenerate pixels to disrupt SynthID.

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.
The four-point star Gemini adds bottom-right is located and the surrounding image detail is reconstructed so the patch blends into the scene.
Local diffusion / SDXL regeneration disrupts the imperceptible SynthID pattern in the pixels. The detector is proprietary, so removal is not guaranteed.

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.
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.
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.
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.

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.
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.

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.
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.
