Remove watermark from image

ClearPix removes watermarks from images entirely in your browser. Auto-detect marks text and logo watermarks, then MI-GAN inpainting rebuilds the pixels underneath; an optional LaMa HQ engine handles large areas. It is free and unlimited, with no sign-up — your image never leaves your device. PNG, JPG and WebP files are supported.

AI finds the watermark for you — review the boxes and remove. Brush is there for touch-ups. Everything runs in your browser; your image is never uploaded.

What local processing means

Your family photo or original artwork is read by the browser and masked on your device; it is not uploaded to a processing server or deleted later on a schedule. The detector, inpainting model and runtime still download from ClearPix, and public sample assets may load. Once those required files are cached, you can disconnect and remove marks offline. Anonymous product events never include the image or its filename.

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.

Watermark removal FAQ

How can I remove a watermark from a photo online for free?

Drop the photo into ClearPix, let auto-detect frame the watermark, and press Remove — the AI rebuilds the covered pixels from the surrounding texture. It is free and unlimited: no account, no credits, and no watermark on the exported file. The first run downloads the AI models (about 34 MB) once and caches them on your device.

Does the watermark remover work on logos and full-screen tiled watermarks?

Yes. Small corner logos are handled by the fast MI-GAN engine; large or tiled marks — like stock-photo grids — are better served by the optional HQ engine (LaMa, a 108 MB model downloaded only if you enable it). Semi-transparent stamps and text overlays work the same way: anything inside your mask gets rebuilt.

Is my photo uploaded to a server when I remove a watermark?

No. The image is read and processed locally by ONNX Runtime Web, on your GPU via WebGPU or on your CPU via WebAssembly. You can watch the network panel: nothing is sent. The only downloads are the AI models themselves, fetched once and cached for offline reuse.

What image formats and sizes are supported?

PNG, JPG and WebP work best. There is no file-size quota — the practical limit is your device memory, and oversized images can be shrunk in one click before processing. Exports keep your original resolution; you can also run the remover twice over stubborn areas, since 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.
