Free In-Browser Watermark Remover — No Upload, No Watermark On Output

Why we built this: Most "free" watermark removal websites are predatory traps. They either blur the entire image, slap their own massive watermark over your photo, force you into a $19/month subscription after one export, or upload your sensitive photos to unverified third-party cloud servers. We believe basic photo restoration belongs on your device — free forever with zero privacy compromises.

How it works: 1) Drop your image (JPG, PNG, WebP) — it loads entirely in your browser memory and never leaves your computer or phone. 2) Paint over the unwanted watermark, logo, date stamp, or object with the interactive brush. 3) Click "Erase Watermark" to execute the mathematical Telea Fast Marching inpainting algorithm directly on your canvas pixels in under 0.2s, then download your clean image instantly.

The inpainting engine runs on your device's local CPU using pure HTML5 Canvas pixel manipulation. It reconstructs the background texture by propagating neighboring pixel color gradients inwards, creating a seamless fill that blends naturally with surrounding colors.
