A preview first. A useful answer next.
Your camera usually puts a JPEG inside each RAW. This tool reads that preview on your device, even when your browser cannot display the RAW itself. Then it checks your chosen camera against Apple’s published support list for your macOS generation, keeping mode restrictions visible.
The preview is the camera’s finished rendering. It does not test the sensor data, repair a file or prove that a desktop app will decode it. If you need a JPEG download, use our RAW to JPEG extractor. For camera settings and location fields, use the EXIF viewer.
Open ARW, CR3, NEF, RAF and DNG on Mac
- Sony ARW: confirm your exact Alpha model and RAW mode. Open ARW on Mac.
- Canon CR3 and CR2: standard RAW and C-RAW may have different requirements. Open CR3 on Mac.
- Nikon NEF: check Lossless versus High Efficiency and the installed macOS version. Open NEF on Mac.
- Fujifilm RAF: compressed, lossless and uncompressed modes can differ. Open RAF on Mac.
- DNG: support depends on how the file was created, including the compression used by phones and converters. Open DNG on Mac.
For Olympus ORF and Panasonic RW2, an embedded preview may be smaller than the full RAW. Explore RAW formats in RevelRaw or download sample RAW files to try.
Where the compatibility answers come from
The bundled camera lists were checked on November 10, 2026 against Apple’s official pages for macOS 13, macOS 14, macOS 15, macOS 26 and macOS 27. Each list describes the latest updates in that macOS generation. It does not establish the first minor release that supported a camera.
“Apple lists this camera” means a published listing, not a test of your file. “Not confirmed” means no exact match in our snapshot; cameras absent from a list can still work. Confirm your model and check the linked source. Any full RAW decoding test shown is dated separately. Apple support is never presented as a RevelRaw test.
When your RAW still will not open
Try a second original from the same camera. Confirm that the file has finished downloading from cloud storage, install the latest macOS update available to your Mac, and check the capture mode. If only one file fails, try another copy from your backup or card. Follow our RAW troubleshooting guide for the complete sequence.
Edit your original in RevelRaw
RevelRaw is our native Mac RAW editor. Choose a look, adjust light and color, and export your first photo at full quality for free. Photos stay on your Mac. The app requires macOS 26 or later and Apple M1 or later; try a file from your own camera to confirm support.

Frequently asked questions
Is my RAW photo uploaded?
No. The file is read in your browser. Your photo, filename and extracted metadata are not sent to a server. Compatibility uses a bundled public camera list; the sample button downloads a public sample file.
Does seeing the preview mean my RAW file is healthy?
No. This tool displays the JPEG embedded by the camera. That preview can remain intact even when the sensor data is incomplete. Open the original in a RAW editor to check the full image.
Why does Apple list my camera but Preview will not open my RAW?
Camera support can depend on the capture mode and the installed macOS update. High Res Shot, pixel shift, compressed RAW and other special modes can have separate restrictions. Check the exact model, mode and macOS version.
Can this tool check a camera without a file?
Yes. Enter or choose the camera model, select your macOS version and chip, and check compatibility. You can use the camera lookup even if your file has no usable embedded preview.
Can RevelRaw open a file that Preview cannot?
Sometimes. RevelRaw tries the Mac’s RAW decoder and then a second built-in decoder. Camera and mode support still need a test with your original file. The app requires macOS 26 or later and Apple M1 or later; editing and one full-quality export are free.
What files can I preview here?
The browser parser reads ARW, SR2, SRF, CR3, CR2, NEF, NRW, RAF, ORF, RW2 and DNG files up to 256 MB. Not every file contains a usable JPEG preview. Other cameras can still be checked manually; browser-preview coverage is separate from macOS and RevelRaw support.
