FastRawViewer
FastRawViewer is a macOS photo utility for quickly viewing, rating, and sorting RAW images using data from the original camera files.
What is FastRawViewer?
FastRawViewer is a desktop photo utility for photographers who need to review RAW images quickly before editing or ingesting them into a larger workflow. It is designed for culling, exposure evaluation, and first-pass selection using the original RAW data rather than relying only on embedded JPEG previews. On macOS, users commonly use it to inspect focus, compare exposures, assign ratings and labels, and move through large shoots efficiently. The app supports many camera RAW formats along with JPEG, TIFF, and PNG files, which makes it useful in mixed folders and memory-card workflows. It can also write XMP sidecar metadata so selections and adjustments can carry into compatible editing applications. FastRawViewer is published by LibRaw LLC and is aimed at photographers who want a fast review step between capture and full photo editing.

Safety overview
Status: Safe
FastRawViewer is a legitimate desktop photography tool. Access to photos, folders, and external media such as memory cards is normal for its purpose, and removing it mainly affects your ability to use its viewing, rating, and metadata workflow. If you rely on XMP sidecars or stored preferences in your photo process, keep related data until you confirm you no longer need it.
Recommendation: Keep FastRawViewer if you use it to review or cull RAW photos on your Mac. Remove it only if you no longer use its photo-selection workflow, and consider keeping any sidecar metadata or settings you may want for future projects.
