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. ## Installation 1. **Download the official installer** — Download the FastStone Image Viewer 8.5 installer (FSViewerSetup85.exe) from faststone.org using the button above and save it to your Downloads folder. 2. **Run the installer** — Run the EXE, accept the licence terms shown in setup, and complete the standard installation; a portable ZIP package is also offered on the vendor's page if you prefer not to install. 3. **Finish and launch** — Launch the viewer, point it at a photo folder, and double-click any thumbnail to experience the full-screen mode — move the mouse to each screen edge to reveal the hidden toolbars. ## Editorial verdict FastStone Image Viewer is the kind of program long-time Windows users install on every new PC without thinking, and a week with version 8.5 shows why. Browsing a folder of several thousand photos is instant, the four-image comparison view is the fastest way we know to pick the best frame from a burst, and the full-screen interface — where every toolbar hides at a screen edge until your mouse touches it — remains a genuinely brilliant piece of design that newer viewers still copy. Batch conversion and renaming, red-eye removal, EXIF inspection and slideshow building mean many people never need a second program for everyday photo jobs, and the format support keeps growing, with SVG and better PDF handling arriving in 8.5. Two qualifications belong in any honest recommendation. First, the licence: FastStone is free for personal and educational use only, and using it as part of a business requires a paid licence (listed at $34.95), so it should never be described — or deployed at work — as simply free. Second, the interface is undeniably dated, with dense menus and small icons that assume a mouse-and-keyboard desktop workflow rather than touch. Neither point dents its usefulness at home, where it remains arguably the most capable free-for-personal-use photo browser on Windows, but both are worth knowing before you commit to it. ### Strengths - 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. ### Trade-offs - 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. ## FAQ **Is FastStone Image Viewer free?** It is free for personal and educational use.
