Gemini Watermark Removal — FAQ
Are my images really not sent to any server?
100% guaranteed. All processing happens in your browser’s Web Workers — image data never leaves your device. You can verify this by using the tool while offline.
What image formats are supported?
PNG and JPG/JPEG formats are supported. Google Gemini typically generates images in PNG format — all handled flawlessly.
How good is the removal? Will it degrade image quality?
Our reverse alpha blending algorithm precisely restores original pixels, with error within ±1 — completely imperceptible. Pixels outside the watermark area remain untouched — effectively lossless.
How fast is it?
Using Web Worker multi-threaded architecture with full multi-core CPU utilization. A single image typically completes in under 100ms; batch processing dozens of images takes just a few seconds.
Can this remove watermarks from non-Gemini images?
This tool is specifically designed for the semi-transparent star watermark generated by Google Gemini. It is not suitable for watermarks from other AI models or manually added watermarks.
Is registration or payment required?
Not at all. Open the page and start using it — no usage limits, no hidden fees, free forever.
