What is skylum-cloud-exe?
skylum-cloud-exe is the background service that powers Skylum Cloud synchronization across your devices. It keeps Luminar libraries, presets, and photo metadata in sync with the Skylum cloud, handles fast indexing, cloud backups, and lightweight update checks to ensure assets stay current across computers and laptops.
It runs as a background process, communicates with Skylum cloud servers over secure APIs, and maintains a local index of assets to sync changes without blocking the main Skylum apps.
Quick Fact: Skylum Cloud introduced cross-device library syncing, so edits to metadata and presets propagate to other devices where Skylum apps are installed.

- Update Check: Checks for cloud client updates and patches

Is skylum-cloud-exe a Virus or Malware?
The real skylum-cloud-exe is NOT a virus. However, malware can imitate names to trick users.
How to Tell if skylum-cloud-exe is Legitimate or Malware
- File Location:: Must be in
C:\\Program Files\\Skylum\\Skylum Cloud\\skylum-cloud.exe or C:\\Program Files (x86)\\Skylum\\Skylum Cloud\\skylum-cloud.exe. Any other location is suspicious.
- Digital Signature:: Right-click the file in Explorer → Properties → Digital Signatures. Should show "Skylum Ltd." as the signer.
- Resource Usage:: Normal usage is 3-12% CPU and 60-180 MB memory. Extremely high usage when idle is suspicious.
- Behavior:: Skylum Cloud should run in the background only when syncing or updating. Persistent activity with no user action may indicate malware.
Red Flags: If skylum-cloud-exe is located in unusual folders (like Temp, AppData\Roaming, or System32), runs when Skylum apps aren’t open, has no digital signature, or uses abnormal resources constantly, scan your system with antivirus software immediately. Look for similarly-named files like "skylum-cloud.exe" from untrusted sources.
