What is logseq.exe?

logseq.exe is the Windows desktop executable for Logseq, a local-first knowledge base and outliner. The process launches when you start the app and may spawn multiple renderer processes for open notes and plugins. It stores data in your user profile and can sync when enabled.

This architecture uses Electron/Chromium with a main host and separate renderers for notes and plugins. It provides isolation for stability and supports fast rendering and graph indexing.

Quick Fact: Logseq began as a knowledge management tool emphasizing local-first graphs and bidirectional linking.

Types of Logseq Processes

Main Process: Host window and global UI (1 instance)
Renderer Process: Each open page/note renders in its own process
Background Sync Component: Syncs changes with the local or remote graph
Plugin Process: Plugins run in isolated processes
Indexing Service: Indexes notes for fast search
Utility Process: Background tasks and network services

Is logseq.exe Safe?

Yes, logseq.exe is safe when it comes from the official Logseq distribution downloaded from logseq.com or verified app stores.

Is logseq.exe a Virus or Malware?

The real logseq.exe is NOT a virus. Malware masquerading as logseq.exe can exist; verify file location and signature.

How to Tell if logseq.exe is Legitimate or Malware

File Location: Must be in C:\Users\Alice\AppData\Local\Programs\logseq\logseq.exe or C:\Program Files\Logseq\logseq.exe. Any logseq.exe elsewhere is suspicious.
Digital Signature: Right-click logseq.exe → Properties → Digital Signatures. Should show signers like "Logseq, Inc.".
Resource Usage: Normal usage is 2-12% CPU, 120-420 MB memory. Abnormally high usage with no active tasks is suspicious.
Behavior: Logseq should run when you open the app. Unexpected background activity when the app is closed may indicate malware.

Red Flags: If logseq.exe is located in unusual folders (like Temp or System32), runs when Logseq isn't open, has no digital signature, or uses excessive resources constantly, scan with antivirus and verify with official sources.

Why Is logseq.exe Running on My PC?

logseq.exe runs when you launch the Logseq desktop app or when a graph is accessed, and may stay resident to support quick resuming and auto-sync.

Reasons it's running:

Active Graph Work: You're editing notes; Logseq loads your graph structure and renders pages, which launches renderers per tab.
Background Sync: Graph sync (local or cloud) runs in the background to keep notes up to date.
Startup Launch: Logseq may be configured to start with Windows or to reopen after a shutdown.
Indexing and Search: On graph changes, indexing tasks run to keep search fast and accurate.
Plugins/Extensions: Installed plugins may initiate extra processes for their features.

Can I Disable or Remove logseq.exe?

Yes, you can disable logseq.exe. It's safe to close Logseq when not in use, and you can uninstall it or stop it from launching at startup.

How to Stop logseq.exe

Close the App: Click the X to close Logseq or use File → Exit. You can also Quit from the system tray.
End Background Tasks: If needed, open Task Manager, locate logseq.exe, and End Task.
Prevent Startup: Task Manager → Startup tab → Disable Logseq
Stop Background Sync: In Logseq Settings → Sync, disable automatic syncing
Remove Plugins: In Logseq, disable or remove plugins that cause extra processes

How to Uninstall Logseq

✔ Windows Settings → Apps → Apps & Features → Logseq → Uninstall
✔ Control Panel → Programs → Uninstall a program → Logseq → Uninstall
✔ Download from the official site again if you plan to reinstall with a fresh setup

Common Problems: High CPU or Memory Usage

If logseq.exe is consuming excessive resources:

Common Causes & Solutions

Large, active graph with many pages: Close unused pages and collapse blocks; consider splitting your graph into smaller subgraphs
Active Sync or Cloud sync: Disable automatic sync or adjust sync frequency in Settings → Sync
Plugins or extensions: Disable or remove plugins one by one to identify culprits, then keep only necessary plugins
Outdated Logseq version: Update to the latest version from the official site
Indexing after graph changes: Allow indexing to complete; consider restarting Logseq to re-index
Hardware acceleration: Disable hardware acceleration in Settings if you experience graphical issues

Quick Fixes:
1. Close unnecessary notes and collapse blocks to reduce rendering
2. Restart Logseq to reinitialize processes
3. Update Logseq to latest version
4. Disable unnecessary plugins
5. Consider turning off Sync or lowering sync frequency

Frequently Asked Questions

Is logseq.exe safe?

Yes, the legitimate logseq.exe from the official Logseq distribution is safe. Verify it was downloaded from logseq.com and that the file path matches C:\Users\Alice\AppData\Local\Programs\logseq\logseq.exe or C:\Program Files\Logseq\logseq.exe.

Why is logseq.exe using so much CPU?

Reasonably high CPU can occur when indexing, rendering many open pages, or syncing. Use the built-in task manager in Logseq (Ctrl+Shift+P) to identify heavy pages or plugins and reduce load.

Can I delete logseq.exe?

Yes, you can uninstall Logseq via Windows Settings → Apps. Your notes are stored in your graph folder, so back up if needed.

Can I disable logseq.exe?

Yes. Close the app, disable startup in Task Manager, and stop background sync or disable open-at-login in Settings.

Where are my notes stored in Logseq?

Notes live in a Logseq graph folder you create. The graph directory is chosen when you create a graph and can be moved; check Settings → Graph Directory to locate it.

How do I back up a Logseq graph?

Back up the entire graph folder regularly (copy to a safe location). Logseq also supports syncing graphs to cloud options if configured.
