What a RAW file is
A camera RAW file holds the data straight from the sensor, before the camera turns it into a normal picture. Every maker has its own type: NEF from Nikon, ARW from Sony, CR2 and CR3 from Canon, DNG from Adobe and some phones. RAW keeps more detail in shadows and highlights, so photographers can change exposure and white balance later. The files are large and ordinary picture apps often cannot open them.
How to open it on Windows and Mac
- On a Mac, Photos and Preview open the RAW files of many cameras.
- On Windows, the Raw Image Extension from Microsoft Store adds support for many cameras in Photos and File Explorer.
- Lightroom, Photoshop and other raw editors develop RAW files on both systems.
- To see a photo without installing anything, drop the file on this page.
When the free web viewer is enough
- You want to see which shot is which, or check focus and framing.
- Along with the raw data, the camera saves a full-size JPEG preview in the file. This page shows that preview, and you can save it unchanged as a JPEG or as a PNG.
- You need a picture to send to a client or to a friend, and the camera's own look is fine.
- The file is read in your browser and never uploaded, so your photos stay on your device.
When it is not enough
The page does not develop the raw data. Exposure, white balance and noise are as the camera set them, so it cannot recover a dark shadow or a burnt sky. Some RAW and DNG files store no preview, and then you will see a message. It was tested with NEF, ARW and CR3 files. To edit, Photo Pro for Windows opens DNG and camera raw files from many cameras, with layers, masks and adjustment layers. For Canon CR3 it opens the embedded JPEG. It is a paid app from the LCTR Store, with no subscription and a free 7-day trial from Microsoft Store, and it is for Windows only. On a Mac, use the web viewer for a quick look or a raw editor.

Questions
How do I open a RAW file without special software?
Drop it on this page. It shows the full-size JPEG preview that the camera saved inside the file.
Is this the real raw image?
No. It is the camera's own JPEG preview. To change exposure or white balance on the raw data you need a raw editor.
Can I save the preview?
Yes. Save the JPEG exactly as the camera stored it, or save a PNG.
Is my photo uploaded?
No. It is read in your browser and never leaves your device.
Which cameras work?
Files from most cameras carry a preview. It was tested with NEF, ARW and CR3 files. Some DNG files carry no JPEG preview; then you see a message.
