## Overview
PixelClean (by Insyra Labs) is a free, 100% in-browser watermark removal studio specifically engineered for synthetic media generated by Google Gemini and Google Veo models.

## Core Capabilities
- **Image Studio:** Inverts visible watermark blend masks on PNG/JPEG images up to full original resolution.
- **Video Studio:** Processes MP4 and WebM video streams frame-by-frame entirely inside the browser using WebAssembly and WebGPU.
- **Client-Side Privacy:** Zero server uploads. Assets are processed purely in local device RAM/VRAM.
- **Free Access:** No signups, no accounts, no subscriptions, and no credit meters.

## The Technical Mechanism: Reverse-Alpha Reconstruction
Unlike conventional "AI watermark removers" that use generative inpainting (predicting and drawing missing pixels, which blurs fine textures and ruins typographic sharpness), PixelClean performs **mathematical reverse-alpha reconstruction**.

When Gemini adds a visible watermark overlay, it performs standard linear alpha blending:
`C_composite = alpha * C_watermark + (1 - alpha) * C_original`

PixelClean knows the exact geometry, sub-pixel positioning, and opacity profile (`alpha`) of the official Gemini watermark mask. By solving the inverse blend equation:
`C_original = (C_composite - alpha * C_watermark) / (1 - alpha)`

PixelClean isolates and subtracts the overlay, restoring the genuine original pixels with lossless mathematical precision.

## Visible Watermarks vs Invisible Watermarks (SynthID)
PixelClean exclusively targets **visible transparent watermark overlays**. It does not alter or remove invisible digital provenance signatures (such as Google SynthID or C2PA metadata).
