[RevelRaw](https://revelraw.com/index.md) is a native macOS RAW editor built around Sony Alpha — `.ARW` is the format it's designed for and the one the interface talks about. But a RAW file is a RAW file: unprocessed sensor data waiting to be developed. So RevelRaw opens the other major brands' formats too. Drag any of the files below in, and AI scene detection ranks 40+ presets against the photo, with the full set of fine-tune controls on top. Everything runs on your Mac; no file ever leaves it.

Browse by brand: [Canon](https://revelraw.com/canon.md) · [Nikon](https://revelraw.com/nikon.md) · [Sony](https://revelraw.com/sony.md) · [Fujifilm](https://revelraw.com/fujifilm.md) · [Panasonic](https://revelraw.com/panasonic.md) · [Olympus / OM System](https://revelraw.com/om-system.md) — each hub collects that brand's formats and guides in one place. Each format below has its own guide — what the file actually contains, which cameras write it, how to open it on a Mac, and how to convert it to JPEG.

## How it works, whatever the badge on your camera

Every format above stores the same thing at heart: one brightness reading per photosite on the sensor, before white balance, sharpening or any in-camera look has been baked in. That's why one editor can develop them all. Open a file in RevelRaw and it decodes the sensor data on your Mac, classifies the scene, and ranks its 40+ presets so the most relevant looks surface first — then you fine-tune exposure, color, curves and grain, and export as JPEG, PNG, TIFF or HEIF with platform presets for Instagram, print and web.

## FAQ

### Does RevelRaw only work with Sony cameras?

Sony Alpha is what it's built around — ARW is the headline format. But RAW files from Canon, Nikon, Fujifilm, Panasonic, Olympus and other brands open all the same: drag one in and everything works on it.

### Does RevelRaw open Canon CR3 or Nikon NEF files?

Yes — along with CR2, CRW, NRW, RAF, RW2 and ORF. Drag and drop or File > Open, then export as JPEG, PNG, TIFF or HEIF.

### What if my RAW file won't open?

Files from a just-released camera can fail until Apple ships a RAW update for that body — the file isn't broken; the software just hasn't met that camera yet. For very old formats, a one-time conversion with Adobe's free DNG Converter usually solves it; keep both files afterwards.

### Does RevelRaw open video files?

No. RevelRaw is a stills editor. Video from your camera needs a video editor.

**Whatever your camera writes, see what's really in the file.** Download RevelRaw, drop a RAW in, and watch it ranked against 40+ presets in seconds — with one full-quality export on the house.
