ACDSee is an image organizer, viewer, and image editor program for Windows, macOS and iOS, developed by ACD Systems International Inc. ACDSee was originally distributed as a 16-bit application for Windows 3.0 and later supplanted by a 32-bit version for Windows 95.[1] ACDSee Pro 6 adds native 64-bit support. The newest versions of ACDSee incorporate modern Digital Asset Management tools like Face Detection & Facial Recognition (Ultimate 2019).
ACDSee's main features are speed, lossless RAW image editing, image batch processing, editing metadata (Exif and IPTC), rating, keywords, and categories, and geotagging. Judging the image quality of a picture is fast due to next/previous image caching, fast RAW image decoding and support for one-click toggling between 100% and fit screen zoom mode anywhere inside the image. Most of ACDSee's features can be accessed via keyboard.
