FAQ
Common Questions
-
Is Qlooq safe? ▾
Yes. Qlooq runs in Apple's sandbox with no network access and no data collection. It can only read the single file you're previewing.
-
How do I enable it after installing? ▾
Go to System Settings → General → Login Items & Extensions → Quick Look and enable Qlooq. Then select any supported file and press Space.
-
Why can't it preview .txt, .pdf, or .plist? ▾
macOS reserves these formats for its built-in previewer. Third-party extensions cannot override system-claimed UTIs.
-
Does it support dark mode? ▾
Yes. All preview formats respect your system appearance and switch automatically.
-
What's the difference between Free and Pro? ▾
Free includes source code and Markdown preview with default themes. Pro unlocks archive and font previews, plus all additional themes and color schemes.
