// how it works

How it works

  1. Choose the right tool

    Generation studio, upscaler, background remover, or photo library — match the tool to the task.

  2. Install it your way

    Desktop apps, Docker images, and portable builds cover most platforms; pick the simplest for your OS.

  3. Add models if needed

    Generation tools need checkpoint files; utilities like upscalers usually bundle everything.

  4. Create or organize

    Generate, enhance, or import — then export, share, or keep building your library.

Non-destructive

Edits stay reversible; originals are never touched.

Batch processing

Run whole folders through upscalers and converters unattended.

Extensible ecosystems

Extensions, scripts, and community presets extend the popular studios far beyond stock.

Smart photo libraries

Self-hosted managers with AI tagging, face recognition, and deduplication.

Questions, answered

Who maintains RawTherapee?

It is an open-source project at RawTherapee/RawTherapee with 419 forks. Check the repo's contributors and recent commits to see how active maintenance is.

Is RawTherapee free for commercial use?

GPL-3.0 — free to use, but derivative works must stay open.

Do I need a powerful GPU?

Generation benefits hugely from one; upscalers and photo managers are far lighter.

Which should I start with?

For generation: a polished studio interface. For enhancement: a dedicated upscaler. For libraries: a photo manager.

Can they match Midjourney quality?

With the right open checkpoints, absolutely — the interface matters less than the model you load.
