Brother Sync Service
brother-sync.exe is safe. It's Brother's official synchronization service that keeps printer/scanner settings and profiles in sync across devices and cloud accounts.
brother-sync.exe is the background client that coordinates synchronization of Brother printers, scanners, and related settings across your devices and cloud accounts. It discovers devices on the network, provisions user preferences, and securely transfers configurations so print and scan workflows stay consistent across machines. The service runs unobtrusively in the background during device changes or scheduled syncs.
Technically, brother-sync operates as a Windows service plus a user client. It authenticates devices with TLS, maintains a local profile catalog, and uses delta sync to minimize bandwidth. It coordinates job queues, handles conflict resolution, and updates printer/scanner settings across devices.
Quick Fact: Brother-sync uses delta updates and device discovery to keep printers and scanners aligned across multiple PCs with minimal network overhead.
Yes, brother-sync.exe is safe when it's the legitimate file from Brother Industries downloaded from official sources (brother.com or pre-installed by manufacturer).
The real brother-sync.exe is NOT a virus. However, malware sometimes disguises itself using similar names to trick users.
C:\Program Files\Brother\BrotherSync\ or C:\Program Files (x86)\Brother\BrotherSync\. Any brother-sync.exe elsewhere is suspicious.Red Flags: If brother-sync.exe is located in unusual folders (like Temp, AppData\Roaming, or System32), runs when no Brother devices are configured, has no digital signature, or uses excessive resources constantly, scan your system with antivirus software immediately. Beware of similarly-named files like "brother-sync32.exe" or "brother-sync.exe.bak" from untrusted sources.
brother-sync.exe runs when you interact with Brother devices or when the client starts, enabling automatic device discovery, profile updates, and queue processing across your network.
Reasons it's running:
Yes, you can disable brother-sync.exe. It's safe to stop the service when not needed, and you can uninstall it if you no longer use Brother devices.
If brother-sync.exe exhibits slow performance or high resource usage, try targeted adjustments to reduce impact while preserving syncing functionality.

No, the legitimate brother-sync.exe from Brother Industries is not a virus. Verify the file path is <code>C:\Program Files\Brother\BrotherSync\brother-sync.exe</code> and that it is digitally signed by Brother Industries, Ltd.
High CPU usage usually occurs during active syncing, large profile updates, or when multiple devices are syncing simultaneously. Pause non-essential devices or review the sync queue in the client.
If you no longer use Brother devices, you can uninstall Brother Sync via Settings → Apps. Deleting the executable manually is not recommended; use the official uninstall path to remove all components.
Yes. Pause or stop sync in the client, disable Windows startup for the service, or stop the Windows service. Uninstalling is another option if you won't use Brother devices.
Brother Sync is designed to prepare devices and profiles for quick use. If you don't need automatic syncing, disable startup in Task Manager or stop the service after installation.
Close unused devices, limit the number of synced profiles, update to the latest version, and enable any built-in memory-saving options in the client settings.
Verify network connectivity, ensure printers/scanners are on and connected to the same network, check firewall rules, and re-run device discovery in the client.
