QuickPreview is a lightweight, open-source file previewer for Windows Explorer. It brings the familiar macOS Quick Look workflow to Windows: highlight a file, press Space, and instantly preview images, videos, music, text, source code, folders, and other formats supported by Windows.

The installer adds QuickPreview to the Start menu and Windows Installed Apps. It also includes a standard uninstaller. The release is self-contained, so a separate .NET installation is not required.
PDF documents now open in an interactive embedded viewer. JSON and XML files are automatically formatted for readability, with the original source preserved when a document is malformed.
Double-click the QuickPreview tray icon, or right-click it and choose Settings. The settings window includes an option to launch QuickPreview automatically when you sign in to Windows. The interface follows the active Windows theme.
Requirements:
- Windows 10 or 11, x64
- .NET 6 SDK
- Inno Setup 6 for building the installer

- Available video formats depend on media codecs installed in Windows.
- Interactive PDF preview uses the Microsoft Edge WebView2 Runtime included with current Windows and Microsoft Edge installations. If the runtime is unavailable, QuickPreview falls back to the Windows system thumbnail.
- Interactive Office rendering is not bundled; QuickPreview uses the system thumbnail when Windows provides one.
- The global Space shortcut currently targets File Explorer windows.
QuickPreview — открытый просмотрщик файлов для Windows в стиле Quick Look на macOS. Выделите файл в Проводнике и нажмите Space: приложение покажет фото, видео, музыку, текст, исходный код, содержимое папок и системные эскизы других форматов.
Настройки открываются двойным щелчком по значку в трее. Там можно включить запуск вместе с Windows. Установщик работает без прав администратора, добавляет ярлык в меню «Пуск» и штатное удаление через список установленных приложений.
