Click to Upload or Drag & Drop Media
Supports JPG, PNG, WebP images & MP4, WebM, MOV videos
Engine Architecture
Built for Uncompromising Precision
Inverse Alpha Reconstruction
Instead of destructive AI inpainting or blur passes, our core engine mathematically solves the exact alpha composition equations ($C_{orig} = (C_{wm} - \alpha \cdot C_{src}) / (1 - \alpha)$) to recover exact pixel values.
100% Client-Side Privacy
Your sensitive images and video media never leave your browser. All computations execute locally via high-performance HTML5 Canvas and WebAssembly workers.
Image & Video Coverage
Full automated detection and removal support for both Gemini static preview/full images (48x48, 96x96 watermark specs) and Veo video watermark overlays.
Workflow Guide
Three Simple Steps to Clean Media
Input Media
Select or drop your Gemini generated JPG, PNG, WebP image or MP4 video into the tool or run automatically on Gemini web app via Userscript / Extension.
Automatic Alpha Recovery
The engine detects the image dimensions, locates the exact watermark anchor offset, and applies reverse alpha blending channel by channel.
Export Clean File
Preview the pristine result with interactive side-by-side comparison, copy the clean image directly to clipboard, or download full-resolution files.

Help & Insights
Frequently Asked Questions
What makes this tool different from generic watermark removers?
Most online watermark removers use generic AI inpainting or content-aware fill, which blurs or invents fake details. DevCart Gemini Watermark Tool uses exact mathematical reverse alpha blending based on Gemini's specific watermark compositing formula, perfectly recovering the original pixel values behind the watermark.
Does this tool alter or downgrade the quality of my images?
No. The reverse alpha transformation acts only on the specific pixels containing the watermark composite. The remainder of your image is untouched, preserving 100% of the original resolution and color fidelity.
Can I run this automatically while browsing gemini.google.com?
Yes. You can install our Tampermonkey Userscript or Chrome Extension. It automatically intercepts Gemini image downloads and preview displays in real-time.
Who maintains this open-source project?
This application is engineered and maintained by Vivek Dalvi under the official DevCart Technologies brand.
