AI Watermark Removal FAQ
Does the AI remover upload images to a server?
No. ImgLab AI watermark removal runs entirely in your browser using WebAssembly. Images are never uploaded to any server.
Is the removal effect good?
For simple backgrounds, results are nearly seamless. For complex textures behind large watermarks, some artifacts may remain and a second pass can improve the result.
What watermark types are supported?
Works on text watermarks, logo watermarks, and stamps. Brush over the area you want removed.
Will it damage the original image?
Only the brushed area is affected. The rest of the image stays untouched. Use Undo to revert any step.
How fast is the processing?
It depends on image size and brushed area. Small areas on 1-2 megapixel images finish in seconds. Large areas on huge images may take longer.
Does it work on mobile?
Yes. The page is fully responsive with touch support. Use your finger to brush over the watermark on your phone.
