User Reviews

Users largely criticize Synology's decision to move core image features from the server to a browser extension and desktop app. They report performance problems and excessive memory usage, privacy concerns from broad page access, and a lack of native HEIC codecs. Linux desktop support is also missing, leaving some users seeking alternatives. Overall, many view this as a trust-breaking change that degrades usability, though a few note it can work as advertised in some setups.

Pros

Cons

Vendor decision to move server-side image handling features to a client/browser extension and a desktop app, forcing extra software and hurting UX and trust.
High memory usage and poor performance, with reports of RAM usage up to 16 GB and crashes.
Privacy/security concerns due to the extension's broad access to all pages/domains and limited configurability.
Lack of native HEIC support and codecs, pushing users to workarounds or open-source alternatives.
No Linux desktop app support; Linux users feel ignored and unsupported.

Recent reviews

Yes, of course I want to install a browser extension plus desktop app to support something that used to work out of the box. Terrible

Useless for linux since this needs a runing windows app in the background

Is Synology Image Assistant Extension Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Synology Image Assistant Extension requires a few sensitive permissions. Exercise caution before installing.
