WatermarkOut

🎯 Why this exists

Watermark removers online charge ₹800–₹2,500 / month ($10–$30), upload your private images to unknown servers, and slap their own watermark on the free tier. That's broken.

WatermarkOut runs entirely in your browser. Your file never leaves the tab. No subscriptions, no accounts, no cloud — verifiable because the source is MIT-licensed and the network tab is empty after first load.

⚙️ How it works (the boring honest version)

1. You drop an image in. The file becomes an in-memory ImageData object in your browser. It never leaves.
2. You paint the watermark. A canvas overlay tracks where you brush — that becomes the inpainting mask.
3. An AI model runs in WebAssembly. The model (LaMa, ~50 MB, downloaded once and cached) runs inside your browser tab via ONNX Runtime Web — on your GPU if your browser supports WebGPU, otherwise on your CPU.
4. You download the result. Same browser, same tab, same machine. No server saw a thing.

Open your browser's Network tab to verify: after the first load, no requests are made.
