What is the Nano Banana watermark?

It is the small visible logo added to many Gemini image downloads. Banana Clean removes that visible logo while leaving invisible provenance systems such as SynthID alone.

Can I remove a Nano Banana watermark from a saved file?

Yes. Open Manual Cleanup, load the saved image, brush over the visible logo and download the cleaned PNG.

Can Banana Clean clean Nano Banana Pro images?

Yes. The extension and manual cleaner are designed for the visible Gemini/Nano Banana watermark family, including Pro image downloads.

Why do I sometimes see the mark away from the corner?

Some Gemini outputs place the visible mark slightly differently because of aspect ratio, UI export path or generated content framing. Manual Cleanup is useful for these edge cases.

Remove the Nano Banana watermark from Gemini images

Nano Banana, Nano Banana Pro and Gemini image exports can carry the same small visible mark. Banana Clean gives you two workflows: automatic cleanup from the extension, and manual brush cleanup for saved images or hard leftovers.

Start with the workflow you need

One saved image: use Manual Cleanup. Paint over the mark, run the local AI cleanup and download the result.
Regular Gemini downloads: install the extension and use the official Download button in Gemini or AI Studio.
Supported MP4 videos: OMNI Video is a separate plan inside the extension for Gemini and Google Flow video downloads.
Hard backgrounds: use the manual brush on marble, glass, fabric, water, skin, product shots or any place where a tiny trace remains.

Why a Nano Banana-specific page exists

People search for both names. Some type "Gemini watermark remover"; others type "Nano Banana watermark remover" because the visible logo is tied to the image model branding. This page keeps that path clear and links to the same Banana Clean tools.

The visible logo is not SynthID

The small visible mark is only one part of Google's AI provenance stack. SynthID is invisible and remains in the image data. Banana Clean removes visible marks for presentation and editing. It does not remove or hide invisible provenance signals.

For shifted marks, brush is safer

Most Gemini image marks sit near the lower-right corner. Some outputs shift the mark slightly because of aspect ratio or export path. In those cases a manual brush is safer than forcing a fixed corner mask: you select the exact area and leave the rest alone.

FAQ

Is Nano Banana different from Gemini for cleanup?

For users, it is the same visible watermark family. The search wording changes, but the cleanup workflow stays the same.

Can I clean Nano Banana Pro outputs?

Yes. Use the extension for supported downloads or the manual cleaner for saved files and shifted marks.

Does the online cleaner run locally?

Yes. The manual cleanup model runs in your browser. Optional sample upload needs explicit consent.

Does it work on videos?

The image cleaner does not process videos. The extension has a separate OMNI Video cleanup plan for supported Gemini and Flow MP4 files.
