Remove Gemini and Nano Banana watermarks from images

When you generate an image with Google Gemini or Nano Banana, it contains a specific stack of markers:

• Visible sparkle logomark: A semi-transparent overlay placed in the corner of the image.
• Hidden SynthID marker: An invisible pixel pattern designed to survive cropping and compression.
• Embedded Metadata: C2PA Content Credentials and EXIF tags noting the AI origin.

To address all three layers, we recommend the All-in-one mode on the homepage.

It erases the visible sparkle first. Then it uses a cloud GPU to disrupt the hidden SynthID pattern while preserving visual fidelity. Finally it strips the file metadata. No tool can guarantee the SynthID pattern is gone, so check the result in the Gemini app, Google's own verifier.

1. Add the Gemini or Nano Banana image to the uploader on the RAIW homepage: PNG, JPG, WebP, AVIF or HEIC, no signup.
2. RAIW reads the file first and lists what it found: the visible sparkle, C2PA Content Credentials and, when Google's credentials are still in the file, the SynthID marker they declare.
3. Quick clean is free within the daily allowance: it removes a detected visible sparkle, strips the metadata and leaves the other pixels unchanged.
4. All-in-one is paid: it also regenerates the image on a cloud GPU to disrupt the invisible SynthID marker, keeping the picture as close to the original as it can.
5. Download the result and check it in the Gemini app. RAIW never claims an image is undetectable.

We keep uploaded originals for research, ordinarily for at least 12 months. Processed results expire after 90 days. We never sell your images. See our Privacy Policy for deletion requests and details.
