Ultimate Window Manager for Windows Multitasking
WindowTop is a powerful Windows window manager and productivity tool that lets you keep any window always on top, create floating Picture-in-Picture (PiP) windows, adjust window opacity and transparency, and easily manage multiple windows with Anchors.
Whether you want to overlay transparent windows while working, watch videos while gaming, or reduce eye strain with Dark Mode, WindowTop gives you full control over your Windows desktop multitasking. Start using it for free and unlock advanced features with the Pro version!
Always on Top – Keep Windows Visible While You Work
Keep any window always on top of others and highlight it with a customizable colored border. Easily adjust frame color, thickness, and behavior from the Always on Top settings — perfect for multitasking, monitoring apps, or staying focused while working.
Picture-in-Picture (PiP) & Crop — Watch and Work with Any Window
Easily watch videos or monitor any window while working using Picture-in-Picture (PiP) mode. You can interact directly with PiP windows, keep them floating above your work, and even crop specific areas of the window to focus only on what matters.
Update: Since 5.29, we have added support in Crop to automatically detect crop regions (see the second tab)
Anchors – Instantly Access Windows with One Click
Need faster access to your windows? Anchors let you instantly bring windows to focus with a single click — faster than ALT+TAB and perfect for touchscreens. Instead of keeping windows always on top, use Anchors to quickly reopen minimized or background windows.
Anchors automatically avoid covering text or images by smartly repositioning themselves on your screen.
Opacity with Click-Through – Work Seamlessly Over Transparent
Enable click-through on transparent windows to interact directly with content behind them. Perfect for designers, artists, or anyone tracing, copying, or referencing elements on screen.
Opacity Control – See Through Windows While You Work
Adjust window transparency to see background content while working. Opacity Control lets you overlay windows, compare designs, write code, or follow tutorials without constantly switching windows.
Auto-Move for PiP – Stay Focused, Avoid Distractions
Picture-in-Picture mode includes an Auto-Move feature that intelligently repositions the window to avoid covering important text or images on your screen.
Dark Mode – Reduce Eye Strain at Night
Switch to Dark Mode and reduce screen brightness when working at night or in low-light environments. Apply dark theme even for apps or windows that don’t natively support it.
Note: Stable on Windows 11. May be unstable on Windows 10.
Glass Mode – Smart Transparency with Adjustable Blur
Glass Mode offers advanced transparency control, allowing you to separately adjust opacity for window backgrounds, text, and images. Customize the blur level for a modern, glass-like visual effect. Optimized for NVIDIA GPUs with CUDA acceleration.
Note that this may work slowly on 4K and will work better for NVIDIA GPUs (make use of CUDA feature)

Very useful...
Very good experience, extremally helpful when working on remote desktop!
Works well, but I wish "click through" had a shortcut key, and for some reason I can't turn off the "remember this window" feature.
finally, doesn't work with Dishonored. only game I had it fail so far when trying to have another window lay over top of that game in Fullscreen mode.
I originally installed WindowTop to use overlay a ruler for a game I really liked to play that required it, but didn't have one implemented. After awhile my use of the app evolved to using the "Set Top" and "Opacity" features for timers, watching videos, drawing art, editing/working on spreadsheets, etc. It really helps me maximize the space and potential of my two monitors for whatever I'm doing.
very useful and easy to use
I do a lot of college work, so when I'm doing my lab work I have to enter in notes on my notepad while looking at a video. It was really annoying to click into the video and then the video would cover my notepad. but with this, I can easily click back and forwards with this program. I also like the other things they have on here like translucent feature, the picture in picture feature, the glass feature which allows you look through the program your using to other programs) , etc. Other programs only have the window on top feature but these ones have a few other ones that can help someone too.
This app reduced my frustration so much I can't live without it! (Not exaggerating)
I initially downloaded it to keep windows on top permanently but it offers so much more like making windows transparent or shrinking a window to a small preview on the screen. It makes switching between programs and windows easy and fast. The onscreen icons are also very useful because it makes it easy to identify different instances of the same window or program, like having 3 file explorer windows open.
There are some changes that I would like to see that will move this app from great to perfect. The ability to park onscreen icons and shrinked windows permanently in a position without them moving around. Also better multi screen support. I also hardly ever use the Glass function because it seems to be buggy.
Very helpful for watching videos when I work. Thank you!
I just use the app to pin a visual timer on top of my other windows. That function is available in the free version you can set a hotkey (Alt+Z by default) to toggle the feature on and off for a given window.
