Clean Google Gemini image output

Gemini image generation attaches provenance metadata and a SynthID mark to everything it produces. PurifyAI shows you exactly what is embedded and removes the metadata without recompressing your image.

  • Removes embedded provenance metadata and generator attribution
  • Lossless — the container is rewritten, pixels are copied through
  • Optional mask for a visible corner watermark
  • Free to inspect, no account required

How it works

Three steps, no account required to try it.

1

Load your file

Drop an image or video into the browser. It is read into memory locally — there is no upload request, which you can confirm in your network tab.

2

Review what was found

The engine walks the actual byte structure and lists every metadata segment it finds: C2PA manifests, EXIF blocks, XMP packets and text chunks.

3

Export a clean copy

Metadata segments are dropped and the remaining bytes are rewritten. Pixels are untouched, so there is no re-encode and no quality loss.

What this tool handles

🔬

Byte-level inspection

See every metadata segment with size and a readable preview before anything is removed.

🎨

Colour-safe

ICC profiles survive the scrub, so wide-gamut images do not shift.

🖼️

Image editor built in

Crop to any aspect ratio, rotate, and adjust exposure and colour in the same pass.

🎯

Corner logo masking

If your export carries a visible mark, mask and reconstruct that region too.

📦

Batch mode

Strip metadata across a whole set of Gemini exports in one queue.

🔌

Pipeline API

Call the same engine from your backend on the Agency plan.

Frequently asked

Does Gemini watermark every image?

Google states that its image output carries SynthID. Part of that is metadata this tool removes; part is an imperceptible pixel-level signal that it does not. Scan one of your own exports above to see exactly what metadata your files carry.

Will this reduce my image quality?

No. Metadata scrubbing rewrites the container around your image data — it drops the metadata segments and copies the pixel data through byte for byte. There is no decode and re-encode step, so the output is pixel-identical to the input. ICC colour profiles are deliberately preserved so colours do not shift.

Do my files get uploaded anywhere?

No. The scrubbing engine is JavaScript running in your own browser tab. There is no upload endpoint and no server-side processing queue, so your media never leaves your device. You can verify this by opening your browser network tab while you scan a file.

What is "Nano Banana"?

It is the nickname that stuck to Google’s image editing and generation model in the Gemini app. Whatever it is called in the interface, the file-level behaviour this tool acts on is the same.

Is it legal to remove watermarks and content credentials?

It depends entirely on the media and your intent. Removing marks from work you own or are licensed to edit is normally fine. Stripping provenance data to pass AI-generated media off as authentic in journalism, elections, legal evidence or identity documents is prohibited by our terms and may be unlawful where you are. You are responsible for how you use the output.

Is there a free tier?

Yes. You can scan and inspect files without an account at all. A free account adds a daily cleaning quota, and paid plans raise that quota and unlock batch processing and API access.
