Clean visible sparkle mark

Standard & non-standard sizes

100% browser-local processing

The Gemini Visible Watermark Remover is designed to clean the visible ✦ sparkle mark that may appear in the bottom-right corner of Gemini images. Separately, Google may embed invisible SynthID watermarks for AI provenance. This tool focuses on visible mark cleanup and does not claim to remove SynthID. For standard sizes, it uses alpha-channel reversal to restore covered pixels where possible. For non-standard sizes, it detects the sparkle area and uses inpainting as a browser-local fallback. Your image is not uploaded.
