From FastStone to macOS
A FastStone Image Viewer alternative for Mac
FastStone distributes Windows installers and has no native Mac release. Seula covers its photo browsing and culling workflow, including ratings and visual comparison.
Where Seula stops: It does not include FastStone's editing, conversion, capture, printing or slideshow tools.

Feature comparison

|---|---|---|
| Platform | Windows | Native macOS app, macOS 12+ |

| Camera RAW | Wide built-in camera format list | Uses the RAW decoders included with macOS |
| Ratings | Stars and tags stored in FastStone's database | Stars, color labels and flags stored as XMP |
| Visual comparison | Up to four images side by side | Compare and Survey modes with synchronized inspection |

Our take
Do you need a toolbox or a culling app?
FastStone Image Viewer is a much broader program. If you rely on its editing, batch conversion, screen capture, printing or slideshow features, Seula will feel incomplete.
Seula makes sense when the job ends at choosing photographs. It adds focus peaking, autofocus point overlays and portable XMP decisions, then leaves editing to Lightroom, Capture One or another editor.
