Bring macOS “Quick Look” feature to Windows


One of the few features I missed from Mac OS X is Quick Look. It allows the user to peek into a file content in lightning speed by just pressing the Space key. Windows, on the other hand, does not has this handy feature … until now.

I am aware that several alternatives are already available on the Internet (e.g. WinQuickLook and Seer). Despite these options, I still decide to craft another one by myself, because they are either not being actively developed, lacks variety, or asks for an amount of $$$.


  • Tons of supported file types (full list here)
  • Fluent design (new in version 0.3)
  • Touchscreen friendly
  • HiDPI support
  • Preview from Open and Save File Dialog
  • Preview from 3rd-party file managers (see a list here)
  • Easy extended by plugins
  • Strict GPL license to keep it free forever
