RawTherapee for PC: How to Download and Install on Windows (2026 Guide)

Your camera’s raw files hold far more detail, colour, and recoverable light than the JPEGs it hands you — but Windows cannot do much with them on its own, and the best-known raw editors are subscription software. If you shoot in raw and want full control over your photos without paying every month, you need a proper raw processor.

This guide shows you how to download RawTherapee for PC from its official website, install it on Windows 11 or 10, and develop your first raw photo. Features, system requirements, and first-use steps are covered below — along with the simple pricing picture, because RawTherapee is completely free and open source.

What Is RawTherapee?

RawTherapee is a free, open-source raw image processor for Windows, macOS, and Linux. It takes the unprocessed data from your camera’s sensor — files such as CR2, CR3, NEF, ARW, RAF, and DNG — and gives you precise tools to develop them into finished photos you can export as JPEG or TIFF.

The important word is “non-destructive”: your edits are stored as instructions in a small sidecar file, never burned into the original image. You can revisit a photo years later, undo every change, or try a completely different look, all starting again from the untouched raw data. Despite costing nothing, RawTherapee is a serious tool used by hobbyists and working photographers alike.

Key Features of RawTherapee

Non-destructive raw editing: Every adjustment is saved as an instruction set, so your original camera files are never modified.
Wide camera support: Opens raw files from almost every major camera maker, plus DNG, JPEG, TIFF, and PNG images.
Precise exposure and tone tools: Exposure compensation, tone curves, shadow and highlight recovery, and strong highlight reconstruction for blown-out skies.
Advanced colour controls: White balance, channel mixer, HSL adjustments, and colour toning for a signature look.
Detail and noise tools: Edge-aware sharpening, micro-contrast, and noise reduction that cleans high-ISO shots while keeping texture.
Lens corrections: Corrects distortion, chromatic aberration, and vignetting, with automatic lens profiles for many cameras.
Batch processing: Apply one editing profile to a whole folder of photos and queue the exports to run in the background.

System Requirements

Operating System: Windows 11 or Windows 10 (64-bit)
Processor: Any modern Intel or AMD CPU; a multi-core processor speeds up exports noticeably
RAM: 4 GB minimum; 8 GB or more recommended for large raw files
Storage: About 1 GB for the program, plus space for your photo library
Display: 1920×1080 or higher recommended, so panels and previews have room
Internet: Only needed for the download
Account: None — no sign-up, licence key, or activation

How to Download RawTherapee (Official Method)

RawTherapee’s popularity means plenty of third-party download portals repackage it with bundled extras or outdated builds. Those copies are not worth the risk, and there is never a reason to use them. Download RawTherapee only from its official website, where the developers publish the current stable release for free.

Step-by-Step Installation

Open the official RawTherapee downloads page linked above.
Click the Windows 64-bit download to get the installer file.
Save the installer to your Downloads folder.
Double-click the installer and approve the Windows permission prompt.
Accept the licence agreement (the GPL open-source licence) and keep the default installation folder.
Click Install, then Finish when the setup completes.
Launch RawTherapee from the Start menu — the file browser opens first.

First-launch note: On the first run, open Preferences and choose your default processing profile and the folder where exported photos should go — two minutes here saves confusion later.

How to Develop Your First Raw Photo

In the File Browser tab, navigate to the folder holding your raw files and double-click a photo to open it in the Editor.
Set the white balance first: use the dropper tool on something neutral in the scene, or pick a preset such as Daylight.
Adjust exposure and the tone curve until the histogram spreads nicely without clipping the highlights or shadows.
Add sharpening and noise reduction in the Detail panel — zoom to 100% to judge the effect honestly.
Crop or straighten with the Crop tool if the shot needs it, checking the horizon against the grid overlay.
Click the queue (export) icon, choose JPEG quality and an output folder, then start the queue to save your finished photo.

RawTherapee Free vs Paid: What Is the Difference?

There is no paid version to compare — and that is the honest headline. RawTherapee is free and open-source software released under the GPL licence. The download from the official website is the complete program: every tool, every camera profile, no trial period, no locked features, and no subscription. It stays free forever, including for commercial photography work.

The project is maintained by volunteer developers and supported by optional donations from users who want to help. Donating is entirely voluntary and unlocks nothing — everyone gets exactly the same software. So if a website ever offers you a “premium” RawTherapee for money, close the tab: the genuine program never costs anything.

Frequently Asked Questions

Is RawTherapee safe to download and use?
Yes, from the official website linked above. RawTherapee is a long-running open-source project whose code anyone can inspect, and the official site serves the genuine installer. The repackaged copies on download portals are the ones to avoid.

Is RawTherapee free?
Yes — completely. It is free and open-source software with no paid edition, no trial clock, and no locked features. You may use it for personal and commercial photography without paying anything.

Can RawTherapee edit JPEG and TIFF files too?
Yes. Although it is built for raw files, it also opens JPEG, TIFF, and PNG images and applies the same non-destructive tools, so older photos can be improved without touching the originals.

How is RawTherapee different from Adobe Lightroom?
Both develop raw photos non-destructively. Lightroom adds a subscription, polished library management, and a more guided interface. RawTherapee is free, works entirely offline, and offers deeper manual control over processing — at the cost of a steeper learning curve.

Conclusion

If you shoot raw, RawTherapee gives you a professional-grade darkroom for exactly nothing: precise colour and detail tools, batch processing, and total freedom from subscriptions. Download it from the official website, develop one favourite photo, and compare the result with your camera’s JPEG — the difference usually settles the question.
