Reception
Upon release, the software site SnapFiles rated it five stars out of five.[7] It also received five stars by the editor of Download.com.[8] A PCWorld magazine review of version 4.0 of FastStone Image Viewer in 2011 noted the software's "lightning-fast" display of pictures. The reviewer felt that one of its greatest advantages was its "wide variety of file formats" the software supports.[9] Rick Broida of CNET wrote in 2015 about version 5.4: "This freeware gem remains an essential download for anyone looking to view, edit and organize their photos." Broida thought that it was a "bit more robust" compared to IrfanView.[3]
