AI Watermark Remover

Remove Gemini and Doubao corner watermarks, or box-select a local region for stronger in-browser cleanup.

Local processing only

Your image stays in the browser. The tool reads the pixels locally, applies the Banana Eraser algorithm, and exports a new file from your device.

Built for AI watermarks and local touch-up

The strongest results still come from the Gemini and Doubao fixed-watermark modes, but Selection repair also helps with smaller localized marks and logos.

Upload an image

Best results come from PNG, JPG, or WebP exports that still keep their original watermark placement or a clearly isolated local mark.

PNG, JPG, and WebP work best

Removal mode

Auto mode reads PNG text metadata when available. You can also switch to Gemini, Doubao, or Selection repair manually.

Watermark type

Auto detection works best for PNG images that still include AIGC metadata.

Gemini mode

Uses reverse alpha blending on the fixed square watermark region in the lower-right corner.

Doubao mode

Samples the background above the watermark and replaces only the masked text pixels in the lower-right corner.

Selection mode

Samples color from the boundary around your box and blends inward, which makes it stronger for local cleanup when metadata-based detection is not enough.

How to use

Upload an image that contains a Gemini or Doubao watermark, or any smaller local mark you want to clean.

Choose Auto, a fixed watermark mode, or Selection repair.

If you use Selection repair, draw a box over the area and adjust expansion or feathering.

Click Remove watermark, review the preview, then download the cleaned file.

FAQ

Frequently asked questions

Which watermarks does this tool support?

It currently targets the two fixed watermark styles used in Banana Eraser: the Gemini lower-right icon and the Doubao lower-right text watermark.

Are images uploaded to a server?

No. The current version reads pixels and exports the result entirely in your browser, which is useful for local-only workflows.

How does auto detection work?

Auto mode looks for PNG text metadata such as AIGC fields or known model markers. If nothing matches, it falls back to the Gemini algorithm and you can still switch manually.

When should I use Selection mode?

Use Selection mode when the image has no usable metadata or when the mark is smaller and more localized than the standard Gemini or Doubao watermark region.

Can it remove any watermark?

Not as a full generic object remover. It is strongest on fixed AI corner watermarks, and Selection mode works better for smaller localized marks with clear boundaries.

Will the output format stay the same?

PNG, JPG, and WebP exports stay in their original family when possible. Unsupported input formats fall back to PNG output.
