How does in-browser watermark removal work?
ClearPix uses MI-GAN, an inpainting neural network from Picsart Research (ICCV 2023), compiled to ONNX and executed by ONNX Runtime Web. Automatic detection combines a text-detection model with visual heuristics; when you confirm the boxes (or paint your own mask), the model analyzes the surrounding texture and synthesizes what should be underneath — on your own GPU via WebGPU, or on your CPU via WebAssembly. The image data never travels over the network, which makes this the most private way to clean up your photos.
Tips for best results
- Let auto-detect run first — dismiss any wrong boxes with one click, then Apply.
- When brushing, cover the whole watermark, slightly overlapping its edges.
- Use a smaller brush for thin text and a larger one for logos.
- Run the remover twice over stubborn areas — each pass refines the fill.
Only process images you own or have explicit permission to modify. Removing a watermark does not change the copyright status of the underlying content.
How it works
Upload the screenshot
Drop the PNG or JPG. Screenshots often carry private conversations or work material — here they stay on your machine.
Let Auto-detect box the marks
Detection runs on load and finds overlay text for you. For faint tiled patterns across the whole image, turn on Deep detection.
Download the clean screenshot
AI inpainting rebuilds the UI or content under each mark at full resolution. Brush over leftovers and re-run.
Your file never leaves your device. All AI processing runs locally in your browser on your own hardware — there is no upload, no queue, and no copy stored on any server. You can disconnect from the internet after the page loads and everything still works.
