About:
Synology Image Assistant is a utility designed to generate high-quality thumbnails and previews for media files stored on Synology NAS devices. It specifically handles modern, high-efficiency formats like HEIC images and HEVC (H.265) videos, which are often not natively supported by older clients. This ensures smooth and fast browsing of photo and video libraries across the Synology ecosystem.
Key Features:
  • Generates thumbnails for HEIC and HEVC formats
  • Offloads processing from the NAS to a client computer
  • Improves performance in Synology Photos and File Station
  • Supports batch processing of media libraries
Use Cases:
  • Accelerating photo library browsing on older Synology models
  • Ensuring compatibility for devices that cannot decode HEIC/HEVC
  • Reducing CPU load on the NAS during media indexing
Alternatives:
  • Synology Photos (Native) – Native on-NAS processing is convenient but can be resource-intensive on older models; Image Assistant offloads this work.
