Gemini Watermark Remover

Where does Nano Banana hide its watermark?

Short answer: bottom-right corner, a four-point sparkle 48 pixels across, set 96 pixels in from the right and bottom edges. If you can't see it, that's the point — it's barely there.

The exact spot

Nano Banana places its mark at a fixed absolute position, not one that scales with your image. In a 1024×1024 image and a 1408×768 one, the sparkle is the same 48 pixels wide and sits the same 96 pixels from the corner. So the bigger your image, the smaller the mark looks relative to the whole frame.

To find it, look at the bottom-right and measure roughly a corner's-worth in: about 10% of the way across a standard image. The shape is a four-point star — two long points (up/down), two short (left/right) — the same glyph Gemini uses, because Nano Bananais Gemini's image model.

The sparkle's box: 48px square, its outer corner 96px in from the right and bottom edges — the same absolute geometry at every image size.

Exact coordinates, by image size

The box runs from (width − 144, height − 144) to(width − 96, height − 96). For the sizes Gemini actually outputs:

Image sizeMark box, xMark box, y
1024 × 1024 (square)880 – 928880 – 928
1408 × 768 (landscape)1264 – 1312624 – 672
768 × 1408 (portrait)624 – 6721264 – 1312

These numbers come from measuring real Gemini output, not from scaling assumptions — a square sample alone is misleading, because 48/1024 and 96/1024 also fit a tidy proportional rule that then predicts a 36px mark on 16:9, where the real mark is still 48px.

Older images: Google has shipped more than one mark

The 48px / 96px geometry is what Gemini stamps today. Images generated earlier in the model's life can carry a variant: in samples we've measured, mark sizes range from about 42 to 56 pixels and insets from roughly64 to 116 pixels, at more than one opacity. Same sparkle shape, same corner — slightly different numbers. If you're hunting the mark on an old download and it isn't exactly 96px in, widen the search a little toward the corner.

Why it's so hard to see

The sparkle is composited at roughly 31% opacity. It doesn't replace the pixels underneath — it's blended over them, like a faint sticker. On a dark, even background it stands out. On a bright sky, a field of flowers, or a light wall, it nearly disappears, because 31% of a pale colour laid over a pale background barely shifts it.

That low opacity is also good news, and it's the reason removal can be clean rather than smudged — more on that below.

Can't find it? You're probably looking at a resized copy

The three usual reasons the sparkle isn't where this page says it is:

It's a screenshot. Screenshots re-render the image at your screen's scale, so the mark shrinks or grows with it and the 48px / 96px geometry no longer holds. Measure proportionally instead: the mark's outer corner sits 96/1408ths of the width in from the corner on a landscape image.
It was re-saved by an app. Messaging apps and social platforms resize aggressively. Same effect as a screenshot.
Your tier doesn't watermark. AI Ultra and AI Studio output has carried no visible mark since March 2026 — there is nothing to find.

Does Nano Banana Pro hide it somewhere else?

No. People search for this expecting Pro to move or shrink the mark — it doesn't. Nano Banana Pro output carries the same sparkle, same corner, same size.

What does change is the tier. Since March 2026, Google ships images withno visible watermark at all to Google AI Ultrasubscribers and in Google AI Studio. Free and Pro (AI Pro) tiers still get the sparkle. So "where is it hidden" sometimes really means "why doesn't my image have one" — and the answer is your tier removed it before you ever downloaded.

Two watermarks, not one

Worth knowing: there is also a second, genuinely invisible watermark. The visible sparkle is cosmetic. SynthID is an imperceptible signal Google embeds in the pixels of every generated image, and no amount of looking will reveal it — it's meant for detection tools, not eyes. Removing the visible sparkle does nothing to SynthID, and no honest tool should claim otherwise.

Now that you've found it, removing it

Because the sparkle is blended rather than stamped, the original pixels under it were never destroyed — only dimmed. That means they can be recovered exactly, not painted over:

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

Our Nano Banana watermark remover does this in your browser — free, no upload — and on something like a night sky you can watch the stars that were under the sparkle come back. The engine is open source if you want to see how. For the full comparison of removal methods, seehow to remove the Gemini watermark.
