About FastStone Image Viewer
FastStone Image Viewer is a Windows image browser from FastStone, the small company also behind FastStone Capture. It combines an Explorer-style folder tree and thumbnail grid with a full-screen viewer, and handles common formats plus HEIC, WEBP, PSD, PDF and camera RAW files. Its editing tools cover the everyday jobs: crop with a rule-of-thirds guide, resize, red-eye removal, colour and levels adjustments, text and drawing on images, and batch conversion and renaming. A compare mode shows up to four images side by side, which is handy when picking the best of a burst. You can also build slideshows with music and email images directly. It is free for personal and educational use with no ads; businesses need a paid licence. There is no Mac or Linux version. It suits photographers and home users on Windows who want one tool to browse, cull and lightly fix photos.
Best for: Windows photographers who want to browse, compare and quickly fix photos in one app.
