ClearPixRemove watermarks from screenshots
ClearPix removes tiled marks, app credit lines and overlay text from screenshots for free, entirely in the browser. Auto Detect boxes visible overlay text on load, and Rect or Paint lets you add faint tiled patterns before AI inpainting rebuilds only the covered area. Screenshots often carry private conversations, so nothing is uploaded: detection and inpainting run locally, and supported runs work offline after the required files are cached.
Erase tiled "confidential" marks, app credit lines and overlay text from screenshots with automatic detection and AI inpainting — entirely in your browser. Free, no sign-up, and your screenshot is never uploaded.

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 hit Remove.
- 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 boxes overlay text for you. Add faint tiled patterns with Rect or Paint, then remove any selection that covers content you want to keep.
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.
Frequently asked questions
What kinds of screenshot watermarks does this handle?
The common ones: diagonal tiled text (like "confidential" or a name), credit lines added by screenshot apps, and semi-transparent overlay text. Interface elements themselves are not watermarks — but you can brush over anything you want gone.
The tiled text crosses text and buttons in the screenshot. Will they survive?
Simple UI edges and flat colors often reconstruct well, but the hidden pixels are not recovered. Dense body text can come back soft, blurred or with invented letter shapes. Use a tighter mask, inspect at 100%, and do not rely on this to restore readable text that was fully covered.
When should I add a manual mask?
When the mark is faint, tiled or low-contrast. Automatic selection is a starting point, not a guarantee; Rect or Paint should cover the pale repeated patterns typical of screenshot stamps before you run inpainting.
Is it okay to remove a watermark from a screenshot?
For your own screenshots and material you are allowed to share, yes. Be careful the other way: a watermark may mark content as confidential or traceable to a leaker — removing it to redistribute restricted material can have legal and employment consequences.
Is the screenshot uploaded anywhere?
No. Screenshots are exactly the files people least want to upload — detection and inpainting run locally in your browser. Supported runs can continue offline after the page, model and runtime files are cached.
How do I upscale a screenshot after removing the watermark?
Download the cleaned screenshot, then open the ClearPix image upscaler and drop the file in — it enlarges images 2× or 4× with Real-ESRGAN super-resolution and exports a full-resolution PNG. Screenshots upscale especially well because their flat UI colors compress cleanly. Everything still runs on your device: no upload, no sign-up.
