Rembrandt

Rembrandt is a free photo editor that develops RAW files and organizes image libraries locally.

Rembrandt is a free photo editor and library manager for macOS, Windows, and Linux. It lets you edit RAW files from over 1,000 cameras using natural language text prompts, touch controls, and AI features like super resolution, denoise, and masks. The software runs locally on your device with no account required for the core app, saving your non-destructive edits as standard XMP sidecar files next to your original photos. It supports imports from Lightroom and other folders, and offers optional paid cloud sync. Built using JavaScript, Rust, WebGL2, and WebGPU, it provides a scene-referred pipeline for clean highlight recovery.
