Optimize your productivity by making windows Always-On-Top. By switching windows super fast using Anchors. By using & watching multiple windows at the same time using Picture-In-Picture (PiP) mode and enabling night mode (dark-mode) for any window.

WindowTop is far more than just a one-feature app. It is an advanced utility app with one goal – to make you much more productive during your work!

Always on Top

Easily set window on top and even highlight top-most window with a red frame! You can configure this behavior in settings (frame color, etc).


The reason why you may put a window on top is to get back to it faster.

If this is your case, then Anchors is for you! Instead of using Always-on-Top, just use Anchors! They will help you to access the window with a single click! Faster than ALT+TAB, great for touch screens!

And don’t worry, the anchors will not disturb you because they automatically move away from any text/image 🙂

PiP for any window!

Want to watch some videos while working?

No problem! Enable Picture in Picture mode for it! It will enable PiP mode.

In addition, you can even interact with the window while it is in PiP mode and even crop a region (See the example!)

PiP Auto-Move!

PiP also come with auto-move option!

It will stay away from text/images for you!


Working on something like building a website and want to see your work behind? No problem! Use opacity

Opacity + Click Through

Opacity also includes a feature that allows you to click through a transparent window. This can be useful for designers and graphic artists.

Dark Mode

Working at night? Tired of all the light coming out of the screen and unfortunately, the software does not support dark mode? No problem now!

Note: Unstable in Windows 10

(Stable in Windows 11)

Glass Mode

Smart transparency mode enables you to take opacity to the next level! Unlike regular transparency, you can set different opacity levels for the background around the text/controls and the images.

And you can even set the blur level.

Note that this may work slowly on 4K and will work better for NVIDIA GPUs (make use of CUDA feature)
