Gemini Watermark Remover is a free web tool that removes the visible Gemini "sparkle" watermark from AI-generated images and videos. Everything runs locally in your browser — your files are never uploaded to any server, so your work stays completely private. No sign-up required, and it works on phones as well as desktops.

Images: the tool detects the watermark in the corner, mathematically reverses the blend, and restores the original pixels — no AI inpainting or repainting. Output is always lossless PNG. You can drop in multiple images at once and download the results together as a ZIP. If no watermark is detected, the tool tells you instead of silently altering your image.

Videos: works with clips from Veo, Veo 3, and Google Flow. A two-pass engine first measures the watermark's exact opacity in your specific video, then removes it frame by frame. The cleaned video is re-encoded to MP4 at high quality, while the audio track is copied as-is with no re-encoding. Video processing is free during launch.

Honesty note: this removes only the visible watermark overlay — it does not remove or alter Google's invisible SynthID marking.
