Raw Image Extension for Windows

Quick previews for camera raw files

Raw Image Extension is a free utility that lets you preview raw photos produced by many digital cameras. Once installed, thumbnails and file metadata are visible directly inside File Explorer, and full-resolution images can be opened using the Photos app for closer inspection.

How it integrates with Windows

Instead of appearing as a standalone program, this extension adds a codec to the operating system so raw formats can be decoded by built-in apps. That means you don’t need to switch between separate viewers — Explorer and Photos handle previews and viewing just like any other image type.

Supported formats and known gaps

• Adds support for a broad selection of mid- and high-end camera raw files, and recent updates introduced CR3 compatibility.
• Does not include support for the GPR format, so those files will remain unreadable until another codec or converter is used.

Benefits for photographers

• Lets you quickly organize and scan large collections by showing thumbnails and EXIF data without launching third-party software.
• Makes high-quality images accessible straight from the OS environment, simplifying workflows that involve culling, tagging, or basic inspection.

Installation tips and final thoughts

• Download and enable the extension through the Microsoft Store or the official distribution channel for your OS.
• Keep in mind it’s a system codec rather than a dedicated image editor; for advanced processing you’ll still want a full raw editor.
  Overall, this extension is a convenient, lightweight addition for photographers who want native raw file visibility in Windows.
