Synology Image Assistant
Synology Image Assistant is a Synology desktop helper for viewing and processing HEIC, HEIF, and HEVC media in Synology Photos web workflows.
What is Synology Image Assistant?
Synology Image Assistant is a desktop utility published by Synology Inc. for use with Synology Photos. On macOS, it works together with the Synology Image Assistant browser extension to generate additional image previews and compressed videos for less-compatible formats, including HEIC, HEIF, HIF, and HEVC media. Synology documents it as part of the workflow for viewing or uploading supported media through Synology Photos in a web browser, and it provides real-time status for generation tasks. The tool is intended for users who manage or browse photos and videos stored on a Synology NAS with Synology Photos installed. Synology also notes macOS support starting from macOS 12.3, with some codec-related limitations on older versions. Users commonly encounter it when Synology Photos asks them to install both the desktop app and browser extension so certain media formats display correctly in the web portal.

Status: Mostly safe
This is a legitimate Synology utility used with Synology Photos. It processes photo and video data for preview generation, so it may access media you browse or upload through supported Synology web apps. Its safety depends mainly on whether you intentionally use Synology Photos and trust the connected NAS and browser extension.
