FastStone Image Viewer vs Tonfotos

FastStone Image Viewer is a Windows image browser, converter, and editor for individual images and collections. Editing tools include resizing, rotation, cropping, color adjustment, sharpening, blur, Clone Stamp, and Healing Brush. It supports major graphic formats and popular camera RAW formats, including HEIC, WEBP, PDF, SVG, and JPEG XL. The Compare Images feature displays up to four pictures side by side, while batch tools convert and rename collections. Slideshows offer more than 150 transition effects and music. The program can acquire images from scanners and batch scan to PDF, TIFF, JPEG, or PNG. Users can launch external editors from within Image Viewer, and a portable version can run from removable storage. FastStone lists personal and educational use as free and a commercial lifetime license at $34.95 as a one-time purchase, with upgrades free. Another plan listing gives a price of $34.95 a month, so the commercial license terms should be confirmed before purchase. The product is listed for Windows, and FastStone provides technical support by email.

Tonfotos organizes photo and video collections, removes duplicates, recognizes people, and helps preserve family histories. Its face recognition groups people and learns from identifications, including faces partly visible or shown at different ages. Users can record relationships and genealogical details, view family ties in a tree, and search an archive by people, events, tags, dates, or shooting locations. Archives can remain on a PC, NAS, or removable drive, with offline use described for disconnected drives or shared folders. TonfotosSync for iOS and Android sends new phone photos to a computer or NAS archive after QR-code pairing. The app can also download photos and videos shared with the user on Telegram. It indexes RAW and HEIC formats and can display HEIC without conversion to JPEG. Other tools include albums, slideshows, photo conversion, and duplicate removal. The free lifetime license has full functionality but limits the number of people in photos. The Personal license costs $59 once and supports unlimited people for one user or device.
