FAQ About AI Watermark Remover
What watermarks can this tool remove?
This tool specifically removes the visible Gemini AI star watermark (bottom-right corner). It does not remove invisible watermarks like SynthID, or watermarks from other AI tools (DALL-E, Midjourney, etc.).
Is the removal lossless?
Yes. The tool uses reverse alpha blending — the mathematical inverse of how Gemini adds the watermark. When the watermark alpha map is accurately reconstructed, the original pixel values are recovered exactly.
Is this legal?
Removing watermarks may violate Google's Terms of Service. This tool is provided for educational and personal use only. Do not use removed-watermark images for commercial purposes without permission.
Are my images uploaded to a server?
No. All processing happens entirely in your browser. Your images never leave your device.
