FastStone Image Viewer review
A free Windows viewer with RAW support, comparison, batch tools, editing, and scanning.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FastStone Image Viewer is a Windows desktop application for browsing, viewing, organizing, comparing, editing, converting, and presenting digital images. It suits Windows users who want more than a basic viewer, particularly photographers and image-heavy workflows that need RAW support, metadata, comparison, batch processing, or scanning. A portable version also supports use without a conventional installation.
Pricing is straightforward by use case. The Personal and educational plan is free for personal and educational use. Commercial users need the Commercial lifetime license, priced at $34.95 one-time, which includes a lifetime license; volume discounts are available. This makes the product a practical fit for individual and educational use, while businesses should account for the license requirement when choosing it for workstations or team workflows.
Its breadth is the main reason to choose it over a narrowly focused viewer. Alongside image browsing, FastStone Image Viewer handles camera RAW formats, EXIF metadata, side-by-side comparison of up to four images, configurable contact sheets, batch image conversion and renaming, cropping, resizing, color adjustment, annotation, printing, slideshows with transition effects and music, scanner acquisition, and batch scanning. Windows users seeking a broad desktop image toolkit should find the feature mix compelling. Those needing software beyond Windows, or only a very simple viewer without editing and batch features, should consider a more focused alternative.
