Where the Nano Banana watermark actually is

Bottom-right, 48 pixels across, inset 96 pixels from the right and bottom edges — the same absolute spot whether the image is square or widescreen. It is a four-point sparkle at roughly 31% opacity, which is why it disappears into a bright or busy photo until you go looking for it. (Still can't spot it? Exactly where to look.)

Google moved it in late June 2026 — the current mark is fainter and sits further from the edge than the one before it. This tool fits both, so images from either era work.

Why the result doesn't look smudged

Most removers paint over the watermark and blur whatever was behind it. This one doesn't guess. The sparkle is composited onto your image as a plain alpha blend:

observed = α · sparkle + (1 − α) · original

That is invertible. The exact overlay is known — recovered by solving the equation against a flat white and a flat black Nano Banana image — so it can simply be subtracted, and the original pixels come back. On a night sky, the stars the sparkle was covering reappear. Nothing is inpainted.

The engine is open source if you want to check that claim.

Nano Banana and Gemini are the same watermark

Nano Banana is the community's name for Gemini's image model. The images it makes carry the identical sparkle, in the identical place, so there is no separate "Nano Banana watermark" to speak of — and no separate tool needed. If you landed here from a Gemini image, the Gemini watermark remover is the same engine with different wording.

What this does — and what it doesn't

Two different watermarks sit on a Nano Banana image. The visible sparkleis cosmetic, and that is what this removes. SynthID is an invisible provenance signal Google embeds in every generated image, and this tool deliberately leaves it alone.

Google already ships watermark-free images to AI Ultra subscribers, so a clean canvas is not the controversial part. Passing AI work off as human-made is — and that would take stripping SynthID. This won't. Use it on images you generated yourself.

Frequently asked questions

Where does Nano Banana hide its watermark?

Bottom-right corner, inset 96 pixels from each edge, and 48 pixels across — the same fixed spot in a square image and a widescreen one. It is a semi-transparent four-point sparkle, so on a busy or bright background it can be easy to miss until you look for it.

Is this the same watermark Gemini uses?

Yes. Nano Banana is the community name for Gemini’s image model, so its images carry the identical sparkle. This page and the main Gemini watermark remover run the same engine — use whichever you prefer.

Does it remove SynthID?

No — and it never will. This removes the visible sparkle only. Google's invisible SynthID provenance watermark stays in the file. A clean canvas is the point; disguising AI images as human-made is not.

Is it free? Do I need an account?

Free, no account, no sign-up. Your image is processed by JavaScript inside your own browser, so there is no server bill to pass on and no upload to consent to.

Will the image lose quality?

No. Only the watermark region changes, and the result is saved as a lossless PNG. Inside that region the original pixels are reconstructed, not blurred over.

Can I generate Nano Banana images without a watermark in the first place?

Google removed the visible watermark for AI Ultra subscribers and in Google AI Studio in March 2026. On the free and Pro tiers the sparkle is still applied, which is why this tool exists.
