About
unbagrnd removes photo backgrounds with AI, with desktop processing kept local and a self-hosted REST API for server workflows. The desktop app uses ONNX Runtime; the maker says images, filenames, and metadata are not sent anywhere. It can handle a single image or a folder, with before-and-after previews as files finish. Users can select from several models to trade speed for accuracy, starting with a 43 MB default. Brush controls erase or restore subject areas with undo and redo, and users can add a solid-color background or an on-device drop shadow. The app predicts a foreground mask on the CPU, composites it with the original pixels, and saves PNG output. The maker says its only network request is a one-time model download, with no analytics, update checks, or telemetry. Its Docker-capable API supports single and batch processing; API images are processed in memory and discarded, not written or logged. The free, MIT-licensed product has no paid tiers or usage limits.
Who it is for
It suits people who want local photo background removal, as well as teams able to run a self-hosted API. Android users should note the APK is not on Google Play.
