About this launch
Mask Bridge is a free, open-source plugin for Adobe Lightroom Classic that allows photographers and 3D artists to export masks as PNG, TIFF or JPEG files. It uses local AI processing to detect and export object silhouettes, supporting both native Lightroom masks and AI-generated selections.
The plugin processes images offline on your computer without requiring an account or internet connection. It works across single photos or entire batches, maintaining matching filenames for masks and images. The tool supports transparent cutouts and offers quality options including Standard for binary masks and HD Fine Detail for detailed subjects like hair and fur.
Mask Bridge is designed for high-end workflows including photogrammetry, Gaussian splatting, 3D object capture and compositing. Ready-to-install builds are available for macOS and Windows under the MIT license, with source code available on GitHub.
