Google Gemini and Nano Banana add a visible watermark (sparkle/logo/text) to AI-generated images and videos, plus an invisible SynthID watermark baked into the pixels. For most creative and experimental use cases, people mainly want the visible logo gone while keeping the original quality and resolution.
Broadly, these tools take two approaches:
- AI inpainting – the tool “guesses” what should be under the watermark and repaints that region.
- Reverse alpha blending – the tool mathematically reconstructs the original pixels using the known way Gemini overlays its logo.
Some run everything locally in your browser (better privacy), others process on a server (more flexibility for edited/compressed files). Below are four free options I’ve looked into, all usable without sign-up.
