Technical Specifications & System Requirements
Software notes
Features
- Folder browsing is extremely fast even with thousands of images, and the up-to-four-images comparison view makes choosing the best shot from similar frames effortless.
- The full-screen mode is superbly designed, hiding EXIF data, the folder tree and editing tools at the four screen edges until your mouse reveals exactly what you need.
- Batch conversion, batch renaming, resizing, cropping, red-eye removal and colour adjustment are all built in, covering most everyday photo jobs in one free-for-home program.
- Format support is broad and current, spanning camera RAW, HEIC, WebP and TIFF, with JPEG XL, PDF viewing and new SVG support added across the 8.x releases.
- Slideshow creation with more than 150 transition effects and music support turns a folder of photos into a presentable show without any extra software.
Considerations
- It is free only for personal and educational use, so businesses must buy a licence, and anyone calling it completely free software is misdescribing the terms.
- The interface looks and feels dated, with crowded menus, tiny toolbar icons and almost no concession to touchscreens or modern Windows design language.
- Its editing tools, while handy, are no substitute for a dedicated editor when you need layers, masking, local adjustments or serious RAW development controls.
About & Overview: FastStone Image Viewer for Windows PC
FastStone Image Viewer is a mature Windows image browser, converter and editor prized for speed and practicality. It browses folders as thumbnails with a large preview, then switches to a full-screen mode where moving the mouse to a screen edge reveals tools, EXIF data and the folder tree. It supports all major formats — BMP, JPEG, HEIC, WebP, GIF, PNG, PSD, TIFF and camera RAW — and version 8.5 adds SVG support and improved PDF viewing alongside the existing JPEG XL support. It also compares up to four images side by side, batch converts and renames, removes red-eye, crops, resizes, adjusts colour, builds slideshows with over 150 transitions, and creates contact sheets. It is free for personal and educational use; commercial use requires a paid licence.
