Core facts

Client-side AI watermark analysis and removal, with no image uploads.

Unmarker.it is a privacy-first browser tool that neutralizes invisible AI watermark signals embedded in images - no uploads, no servers, no data leaving your device. Built on adversarial disruption techniques from recent computer vision research, it applies targeted, mathematically precise perturbations directly in your browser to break machine-readable watermark patterns without visible degradation.

Images stay in the browser

Unmarker.it processes browser-decodable images locally with Canvas API operations. There are no processing uploads, server-side image endpoints, or account requirements.

Analyze, remove, verify

Upload once: Unmarker.it scans metadata and visible marks, runs the local watermark disruption pipeline when possible, then checks the generated JPEG again.

Supported files and output

Processing accepts browser-readable image files up to 40 megapixels and 25 MB. Analysis-only supports PNG, JPEG, WebP, AVIF, HEIF, and JXL metadata.

Designed for honest testing

Results depend on the watermarking method, detector, input image, compression level, and downstream reuse. The tool is meant for privacy research, robustness testing, personal media workflows, and education.
