What Is Lightshot?
Lightshot is a screenshot tool from Skillbrains for Windows and macOS. It lets you capture part of the screen, annotate the image, copy it to the clipboard, save it locally, or upload and share it.
On Windows, Lightshot often runs in the background so its hotkey is always ready. On macOS, it may also stay active to provide quick capture features. It is not part of Windows or macOS.
Is It Safe?
Usually, yes. Lightshot is a legitimate app from Skillbrains and is commonly installed on personal PCs and Macs.
That said, screenshot tools can capture sensitive information if misused. If you do not remember installing it, or if it appeared unexpectedly, check the app location and signature before trusting it. On Windows, right-click lightshot.exe, open Properties, and review Digital Signatures if that tab is present. Also check that it is launching from a normal app location such as Program Files or your user profile's app folders, not from a random temporary or system folder. On macOS, check the app in Applications and confirm it is signed by the expected developer in Finder's Get Info or Gatekeeper prompts.
If Lightshot is asking for screen recording or accessibility permissions on macOS, that can be normal for screenshot and annotation features. Only allow those permissions if you actually use the app.
Should I Disable It at Startup?
Yes, if you do not use it often. Lightshot is optional at startup.
Disabling it will not break Windows or macOS. The main downside is convenience: its screenshot hotkey or tray/menu bar features may not be available until you launch the app manually. If you take screenshots regularly and rely on its quick-capture shortcut, keeping it enabled can make sense.
If you rarely use it, disabling startup is a simple way to reduce background apps.
Why Is It Using High CPU or Memory?
Lightshot normally uses little CPU and memory while idle. Higher usage can happen when it is capturing, editing, uploading, or if it gets stuck after a screen change, update, or permission problem.
If usage stays high, quit and reopen it first. Then check whether another overlay, screenshot tool, clipboard manager, or security app is conflicting with it. On macOS, screen recording permission issues can also cause odd behavior. If the problem keeps coming back, update Lightshot or remove and reinstall it from the official source.
Do not confuse Lightshot with a random process using a similar name. If lightshot.exe is running from an unusual folder or has no valid publisher information, investigate it.
How to Disable or Remove It
On Windows, disable it from Task Manager > Startup apps or Settings > Apps > Startup. You can also remove it from Settings > Apps if you no longer want it installed.
On macOS, check System Settings > General > Login Items and turn it off there if listed. If you want to remove it completely, delete the app in Applications using the normal uninstall method if one is provided.
If you disable it and later want the screenshot hotkey back, just open Lightshot manually and re-enable its startup entry if needed.
Where Kudu Helps
Kudu can show whether Lightshot is set to start automatically and lets you disable or remove the startup entry without hunting through system menus. On Windows, Kudu can also show the startup source and boot impact when available. If Lightshot seems busy in the background, Kudu's Performance Monitor can confirm its CPU and memory use and link the process to its startup item.
Frequently asked questions
- Is Lightshot required for Windows or macOS?
- No. Lightshot is a third-party screenshot app, not a system component.
- Will disabling Lightshot at startup uninstall it?
- No. It only stops Lightshot from launching automatically when you sign in. You can still open it manually.
- Why does Lightshot want permissions on macOS?
- Screenshot tools may need screen recording or related permissions to capture and annotate your screen. Only allow them if you use the app and trust the installation.
