Nano Banana Watermark Remover: Remove the Gemini Logo & SynthID Free
Remove the Nano Banana watermark free — the visible Gemini sparkle logo, Google's SynthID invisible watermark, and file metadata. No sign-up, no quality loss, no watermark of our own added.

What are the watermarks on Nano Banana images?
Nano Banana (Gemini 2.5 Flash Image) marks its exports the same way as the rest of Google's image lineup: a sparkle badge on the artwork, SynthID in the pixels, and provenance metadata in the file. The sparkle badge is what most people want gone — it sits on top of nearly every consumer download.
Upload a PNG, JPEG, or WebP and download a clean, badge-free copy that looks identical apart from the removed marks.
The visible Gemini sparkle logo — a four-point star — is stamped in a corner of most Nano Banana consumer exports.
Underneath it, SynthID embeds an invisible pattern in the pixel data. It survives cropping and re-saving, so removing the corner badge alone leaves the invisible watermark intact.
This tool removes both, plus the standard file metadata, in one pass — you get a clean copy with no visible badge and no hidden SynthID signal.
Google media carries two separate marks and they need two different answers. The visible sparkle logo sits in the corner and can be lifted cleanly. SynthID is woven through the pixels themselves, and Google builds it to survive cropping, resizing, recolouring and recompression — which is exactly why no browser filter removes it, whatever it claims.
The pass on this page does the first job: the logo, the C2PA credentials and the embedded metadata, all locally, with nothing uploaded. SynthID removal is a different operation entirely and runs in the full workflow, which produces media carrying no SynthID signal at all rather than a weakened one. If that is what you need, .
The signals in a Nano Banana image.
- Visible Gemini sparkle logo on the export
- SynthID invisible watermarks — Google DeepMind's pixel-level fingerprinting
- EXIF, IPTC, and container tags in PNG, JPEG, and WebP
- Provenance and generation fields from the Gemini 2.5 Flash pipeline
- C2PA Content Credentials where present alongside SynthID
Four steps, start to finish.
- 01Upload your Nano Banana imagesDrag and drop JPEG, PNG, or WebP files — one image or a batch.
- 02Review what's detectedSynthID, the sparkle logo, and metadata are reported per file.
- 03Remove the watermarksOne click clears the sparkle badge, strips SynthID from the pixels, and removes metadata while the image stays identical.
- 04Verify and downloadCompare with the original and download the clean copy.

What this does not do.
Metadata and pixel-level watermarks are different problems. Anything claiming to clear both in one pass is worth reading carefully.
- The browser pass removes the visible sparkle logo, C2PA credentials and embedded metadata.
- SynthID removal is handled by the full workflow rather than in the browser.
- Screenshots and heavy recompression may have already degraded the visible logo before you get here.
- Removing a watermark does not defeat statistical AI classifiers, which read the picture rather than its metadata.
- Platform AI-disclosure rules apply regardless of what any tool removes.
Watermarks in text work differently.
Everything on this page concerns images, where the mark lives in metadata or in the pixels themselves. Text carries a different family entirely: invisible Unicode characters sitting between the words, which render as nothing and survive every copy and paste.
If that is what you are chasing, the ChatGPT watermark remover reports every hidden character it finds by code point, with versions for Claude, Gemini and Grok. The ChatGPT text cleaner on the homepage runs the whole set of passes at once.
Nano Banana Image Watermark Remover questions.
Does this remove the Gemini sparkle logo from Nano Banana images?
Yes. The visible sparkle badge is cleared along with the invisible SynthID watermark and file metadata, so you download a clean image with no corner mark.
Is Nano Banana the same as Gemini?
Nano Banana is Google's Gemini 2.5 Flash Image model. It watermarks exports the same way as the rest of the Gemini line — sparkle logo plus SynthID plus metadata — so the same removal applies.
Does removing the badge also remove SynthID?
Yes, in one pass. That matters because SynthID is embedded in the pixels and survives cropping — clearing only the visible badge would leave the invisible watermark behind.
Will cleaning change image quality?
No. Dimensions, colors, and transparency are preserved — only the watermark signals are affected.
Will platforms still detect Nano Banana images as AI?
Removing SynthID and provenance stops signal-based detection, but statistical pixel classifiers are separate and may still flag synthetic imagery.
Is this Nano Banana watermark remover free?
Yes — free, no sign-up, and no watermark of our own added.
