🧹 AI Watermark Remover Free Online

Q: What AI watermarks can this tool remove?

This tool removes visible watermarks from Gemini (Google), Doubao (ByteDance), Jimeng (ByteDance), Tongyi (Alibaba), Wenxin (Baidu), and Leonardo.ai. It uses reverse alpha blending to mathematically restore the original pixels.

Q: Is the watermark removal lossless?

For Gemini images, the removal is mathematically lossless because we use the exact alpha map from the official watermark. For other platforms, the result is near-lossless using an estimated alpha map.

Q: Are my images uploaded to a server?

No. All processing happens entirely in your browser. Your images never leave your device.

Q: Can I remove invisible watermarks like SynthID?

No. This tool only removes visible watermarks (semi-transparent logos or text). Invisible watermarks like SynthID, StableSignature, or TreeRing require AI model inference and cannot be removed by this tool.

Q: How do I remove a Gemini AI watermark?

Simply upload your Gemini-generated image (with the star logo in the bottom-right corner), select 'Gemini' platform, and click 'Remove Watermark'. The tool will automatically detect and remove the watermark.
