Camera RAW files hold far more detail than JPEG, but Windows treats them awkwardly: some open, many do not, and folders full of CR2, NEF or ARW files can crawl. Here is how to view RAW photos on Windows quickly, with accurate colors and full resolution.
What RAW files are (and why they are tricky)
A RAW file is the unprocessed data straight from your camera sensor. Every brand uses its own variant: Canon CR2 and CR3, Nikon NEF, Sony ARW, Fujifilm RAF, Olympus ORF, Panasonic RW2, Pentax PEF, plus the universal Adobe DNG. Because each one is different, generic apps often support only a few.
Option 1: Microsoft's Raw Image Extension
Windows can preview some RAW formats with an add-on:
- Install the Raw Image Extension from the Microsoft Store (free).
- The Photos app and Explorer can then show supported RAW files.
Coverage depends on your camera: newer models may not be included yet, and large RAW files can be slow to load.
Option 2: A dedicated viewer that reads RAW natively
For broad format support and fast browsing, use an app built to handle RAW. HawkView reads RAW from most major brands directly, with correct colors and full resolution, and lets you flick through a shoot quickly to cull keepers. There is nothing to configure: open a RAW file, or point HawkView at a folder.
Tips for working with RAW on a PC
- Browse, do not edit blindly: use a fast viewer to pick keepers first, then edit only those.
- Mind the file sizes: RAW files are large, so a viewer that prefetches the next image keeps browsing smooth.
- Convert when sharing: export a copy of a RAW file to JPEG when you need to send it, and keep the RAW as your master.
The bottom line
Install Microsoft's Raw Image Extension for occasional RAW previews, or, for wide brand coverage and fast culling, view your RAW photos in a dedicated viewer like HawkView. If your photos are HEIC from a phone as well, see how to open HEIC on Windows.
