Features:

• Fastest ever: point FastPictureViewer Professional at your image's folder and start reviewing, culling and rating within seconds, in RAW or JPEG format, be it 10 images or 10,000: no wait. Google fastest image viewer and see who comes on top: 3 million users and counting cannot be wrong!
• Full support for 4K & 5K monitors and beyond (perfect scaling, no tiny fonts!) - Full color management.
• True full-screen mode (F10 key removes gadgets, F11 maximizes the view, F12 removes the taskbar: 100% full screen)
• Sort by folder & file name, or by date, forward or reverse (F3 key)
• Best delete functions in industry: Del key (to Recycle Bin or permanent), X-key to tag, then Ctrl+X to delete in batch.
• Tag your photos (star rating) in one keystroke (1-5), filter by rating (F) and copy/move in batch (Ctrl+F)
• While you evaluate an image, FastPictureViewer uses the native 64-bit power of your computer to prepare the next picture. When you are ready to move on, FastPictureViewer displays the next image instantly: no wait, not even a fraction of a second, when your computer has enough spare muscles to load two or more images at once.
