Nano Banana watermark remover
Nano Banana Watermark Remover for the sparkle.
Nano Banana (Gemini 2.5 Flash Image) adds a small four-point sparkle in the bottom-right corner and an invisible SynthID signal across the frame. We clear the visible star and disrupt the hidden signal. This is the Gemini watermark remover tuned for Nano Banana output.

How it works
Upload. We clear the sparkle. You download.
The corner star and the invisible signal, handled in one pass.
We process it privately
We locate the bottom-right sparkle, reconstruct the area behind it, strip supported metadata, and regenerate pixels to disrupt SynthID.

What it removes
The sparkle you see, the signal you don’t.
The Nano Banana sparkle is small and predictable, which makes it removable, but it is only the visible half of what Gemini 2.5 Flash Image embeds.
The 48×48 sparkle
A semi-transparent four-point star sits bottom-right: 48×48px on standard images, 96×96px above ~1024px. We reconstruct the patch so it blends into the scene.
The SynthID signal
Local diffusion / SDXL regeneration disrupts the imperceptible SynthID pattern in the pixels. The detector is proprietary, so removal is not guaranteed.
Provenance fields
Strips supported EXIF, XMP, and C2PA Content Credentials that record the image as generated by a Google model.
The Nano Banana sparkle
Exactly what Nano Banana stamps on an image.
A small, predictable star
Nano Banana is the nickname for Gemini 2.5 Flash Image. Its visible watermark is a semi-transparent four-point sparkle placed in the bottom-right corner, rendered at 48×48px on standard images and 96×96px once the image is larger than roughly 1024px. Its fixed position and size make it a clean candidate for reconstruction, as explained in removing a visible AI watermark.
The invisible half
The sparkle is only the visible mark. Nano Banana output also carries Google DeepMind’s SynthID watermark embedded imperceptibly across the pixels, distributed redundantly so cropping the corner does not clear it. Read what SynthID is and whether cropping removes it for the detail.
Removing both cleanly
We reconstruct the corner where the star sits and separately regenerate pixel content to disrupt the SynthID signal, then strip any provenance metadata. This mirrors the broader Gemini watermark remover flow and the general AI watermark remover. Verify with Google’s SynthID Detector and contentcredentials.org/verify.
Formats, size, and privacy
Uploads can be JPEG, PNG, WebP, AVIF, HEIC, or HEIF up to 20 MB. See the format guide for the best output choice, and private, offline processing for how the image is handled in isolation.
Straight answers
The Nano Banana sparkle, answered.
What is the Nano Banana watermark?
Nano Banana is Gemini 2.5 Flash Image. Its visible watermark is a small semi-transparent four-point sparkle in the bottom-right corner, and its images also carry Google’s invisible SynthID signal across the whole frame.
How big is the sparkle?
It renders at 48×48px on standard images and 96×96px once the image is larger than about 1024px, always in the bottom-right corner.
Can I just crop out the sparkle?
Cropping can remove the visible star, but the invisible SynthID watermark is spread across the image, so cropping alone does not reliably clear detection. We regenerate pixels to disrupt it.
Is removal guaranteed?
The visible sparkle reconstructs well in most cases. The embedded SynthID signal is disrupted by regeneration, but because the detector is proprietary, removal cannot be guaranteed on every image.
What does it cost?
Your first image is free, then one-time credits with no subscription. Larger packs lower the per-image rate.
