Synology Photos is a photo and video management service in DSM for browsing, organizing, searching, sharing, uploading, and previewing media. It requires a Synology NAS for private photo storage, and its mobile app can back up photos and videos to that NAS automatically. Users can share individual items or albums through links with passwords or expiration dates. Shared Space lets selected users collaborate, with access and editing rights assigned by folder. Organization tools include custom and conditional albums, automatic grouping, and facial and object recognition on supported NAS models. RAW files are supported; previews for HEIC/HEVC files and compressed videos require Synology Image Assistant. Mobile apps require iOS 16 or later or Android 11 or later; TV apps support Apple TV and Android TV. Chrome and Safari are recommended for web use. Synology Photos is free, with no paid premium tiers listed.
