Background Remover

Offline, privacy-first background remover for the desktop. Images never leave your machine — models are bundled and run locally.

Built with Tauri 2, Rust, ONNX Runtime (via ort), and Svelte 5.

Features (current)

• Auto — one-click removal via the bundled U-2-Net matte model
• Background replace: transparent, solid color, blur original, or image
• PNG / WebP export with a real alpha matte
• Zoom + pan canvas with the signature transparency checkerboard
• Undo / redo for every mask-changing action
• Dark, gradient-free, instrument-like UI (Geist + Geist Mono)

Coming soon: Smart Select (MobileSAM, encoder-once / decoder-per-click), Manual lasso + brush refinement, and batch folder processing. See CLAUDE.md for the full design.
