RawTherapee

RawTherapee is a free, open-source photo editing application built for photographers who shoot in RAW and want maximum control over their images. It’s not just a basic photo editor – it’s a feature-rich tool designed for precision, offering a professional-grade workflow without the price tag.

Perfect for advanced users and hobbyists alike, RawTherapee brings out the best in your photos with a full suite of editing tools, deep file compatibility, and high-quality processing.

High-end tools with non-destructive editing

What makes RawTherapee stand out is its non-destructive editing workflow. Your original image stays untouched while every adjustment is stored separately. This lets you experiment freely and revisit previous edits without any loss in image quality.

It supports virtually every RAW file format you can think of – from entry-level DSLRs to high-end mirrorless systems. Behind the scenes, a powerful 32-bit floating-point engine handles your edits with exceptional accuracy, so you retain rich color depth and clean tones throughout the editing process.

From tone mapping and color grading to highlight recovery and sharpening, the level of detail you can control is staggering. You can even switch between different demosaicing algorithms depending on your camera and the look you want.

Smart workflow and batch processing

RawTherapee is built to handle large batches of images without slowing you down. Its interface includes a fast file browser, a detailed image queue, and a full-featured editor. You can work through dozens – or even hundreds of RAW files efficiently with the help of batch editing.

It also uses sidecar files to save your adjustments separately from your image. This means you can revisit your projects later and tweak your edits without ever touching the original RAW files.
