RapidRAW is a beautiful, non-destructive, GPU‑accelerated RAW image editor designed for speed and simplicity. It uses a lightweight (~30 MB), efficient code base built with Rust, React and Tauri. Ideal for Lightroom workflows, it offers rich editing tools—exposure, contrast, highlights, shadows, whites/blacks, tone curves, HSL mixer, dehaze, vignetting, film grain, sharpening, clarity and noise reduction—processed in real-time on the GPU.
Features include intuitive masking (brush, linear, radial, AI-powered subject and foreground detection), generative edit layers (via ComfyUI), 32‑bit precision, and full RAW format support through rawler. RapidRAW also provides library management (folder navigation, ratings, metadata, EXIF viewer), batch operations, export presets (JPEG/PNG/TIFF), sidecar editing (.rrdata), undo/redo history, customizable UI themes, smooth animations, resizable panels, and preset copy/paste.
A modern high-performance Lightroom alternative with polished UX and creative tools, RapidRAW brings powerful photo editing to photographers seeking speed, responsive GPU feedback, and streamlined workflows.
RapidRAW 1.4.8 changelog:
New Features
Live Previews
- Editing in RapidRAW is now more fluid and responsive than ever. Previously, adjustments were applied only when you stopped dragging a slider. Now, you can see your changes happen in near real-time as you drag, providing instant visual feedback.
This was made possible by a large rewrite of the GPU processing engine and improvements to the architecture in general. If you prefer the old behavior or are using a less powerful machine, you can disable live previews in the settings.
Updated Collage Maker
The collage maker has been completely overhauled to give you more creative control. Key upgrades include:
- Drag & Drop: No more random mixing! Place your images exactly where you want them.
- Keep Aspect Ratio: A new option to prevent unwanted cropping of your images.
- Zoom & Pan: Finetune the composition within each cell.
LUT Quality Improvement
- Previously, applying some LUTs could result in visible banding or posterization artifacts. This has been fixed by implementing tetrahedral interpolation in the shader, which ensures smooth, high quality color transitions even with lower-resolution LUT files.
Core Improvements
- Separate preview worker, optional high-quality live previews & mask/ai patch caching.
- Enhanced EXIF UI including new infos when hovering the image name in the editor toolbar.
- "Prefer RAW" filter option added to the library.
- Support for uppercase file extensions.
- Thumbnail cache is now flushed on folder switch.
- AI masking stability improvements under load.
- Rawler updated.
