What is zoom-sync.exe?

zoom-sync.exe is Zoom's background synchronization service. It runs alongside the main Zoom client to keep account settings, meeting preferences, and state synchronized with Zoom's cloud and local cache, enabling seamless continuity across devices.

It operates as a separate child process within Zoom's multi‑process architecture, coordinating data exchange with the cloud, updating local caches, and aligning user preferences without impacting the visible UI.

Quick Fact: Zoom uses modular processes to isolate sync tasks from the UI, reducing crashes and improving startup reliability.

Types of Zoom Processes

Core Client Process: Main Zoom UI and core features (1+ instances)
Sync Engine: Handles cloud/local data synchronization for settings and history
Content/Renderer: Renders UI components and in-app content
Update Service: Manages Zoom updates and version checks
Background Tasks: Background data tasks and notifications
Notification Service: Delivers in-app and system notifications

Is zoom-sync.exe Safe?

Yes, zoom-sync.exe is safe when it is the legitimate file from Zoom downloaded from official sources (zoom.us or official app installer).

Is zoom-sync.exe a Virus or Malware?

The real zoom-sync.exe is NOT a virus. However, malware can impersonate legitimate names; always verify the file path and signature.

How to Tell if zoom-sync.exe is Legitimate or Malware

File Location: Must be in C:\Program Files\Zoom\bin\zoom-sync.exe or C:\Program Files (x86)\Zoom\bin\zoom-sync.exe. Any zoom-sync.exe elsewhere is suspicious.
Digital Signature: Right-click zoom-sync.exe f004b open file location f004b Properties f004b Digital Signatures. Should show "Zoom Video Communications, Inc."
Resource Usage: Normal usage is 1-8% CPU, 50-150 MB memory. Extremely high usage when Zoom is not actively used is suspicious.
Behavior: Zoom-sync.exe should run when the Zoom client requires sync and typically settles down when not needed. Persistent background activity without Zoom sign-in warrants investigation.

Red Flags: If zoom-sync.exe is located in unusual folders (like Temp, AppData, or System32), runs when Zoom isn’t open, has no valid signature, or uses excessive resources constantly, scan your system with antivirus software. Be cautious of similarly-named files like "zoom-sync2.exe" from untrusted sources.

Why Is zoom-sync.exe Running on My PC?

zoom-sync.exe runs to maintain up-to-date Zoom settings, cloud data, and meeting state across devices. It may start with Zoom or run as a background sync task to ensure continuity.

Reasons it's running:

Active Zoom Use: You have Zoom open or scheduled sync is required; the engine coordinates data exchange with the cloud.
Background Data Sync: Zoom may sync settings, chat history, transcripts, and meeting data in the background.
Startup Launch: Zoom is configured to start with Windows or to launch sync tasks at login.
Cloud Account Changes: Changes to account settings or device registrations trigger sync tasks.
Data Cache Maintenance: Periodic cache cleanup and validation require temporary synchronization processes.

Can I Disable or Remove zoom-sync.exe?

Yes, you can disable zoom-sync.exe. It may limit cloud sync and background updates, but you can still use Zoom with local data. Disabling is useful for troubleshooting or when bandwidth is constrained.
