A fast, keyboard-driven RAW photo viewer and non-destructive editor for macOS.
Culling hundreds of RAW files should feel instant. Raw Viewer decodes in staged levels (preview → edit quality → 100%), preloads ahead of you, and keeps idle CPU near zero — browsing a full shoot feels like flipping JPEGs.
- RAW and everything else — Canon CR2/CR3, Sony ARW, Nikon NEF/NRW, Fujifilm RAF, Olympus ORF, Panasonic RW2, Pentax PEF, Sigma X3F, DNG, plus JPEG, PNG, TIFF, HEIC/HEIF, AVIF, WebP, BMP, GIF
- Non-destructive develop — white balance, tone curve, HSL, noise reduction and sharpening, automatic lens correction (lensfun), effects, crop and geometry; originals are never touched
- GPU pipeline — WebGL2 renderer, with an experimental WebGPU backend (compute-shader noise reduction)
- Culling workflow — star ratings, pick/reject flags, color labels, filters, RAW+JPEG pairing, grid view, slideshow
- Export — batch JPEG/PNG/TIFF (8/16-bit) and DNG, edit presets, copy/paste settings between photos
- Localized — English · 한국어 · 日本語
