Remove black bars from any video. Fit any video to your entire screen on any video platform — automatically.
UltraWideo is the cross-browser extension that manipulates video aspect ratio to fill your screen. Whether you own an ultrawide monitor (21:9, 32:9), a standard 16:9 display watching 4:3 videos, or anything in between — UltraWideo eliminates black bars and gives you a true full-screen experience.
Why UltraWideo over other extensions?
Unlike alternatives that break on certain platforms or stop detecting videos, UltraWideo is proven to work on all major video streaming platforms, including embedded videos across the web. No "video not detected" errors. No broken layouts on non-video pages. It only activates when there's a video to work with.
▸ Works everywhere — any streaming service, any site with embedded video, any platform. Not limited to a single site.
▸ Blazingly fast — written in plain JavaScript with a tiny footprint. No memory leaks, no background processes draining your battery, no performance degradation over time.

I'm using this extension with Brave on a Mac with a ultra-wide monitor, and it works very well! Just perfect! Thank you so much for developing this.
This the best one ever! You did an amazing job!
This does what is needed for my 21:9 ultrawide when watching clips on youtube that are squished. The problem is that if the video is a regular 16:9 it crops. There was an extension long ago that could automatically distinguish the 2 and you could leave it on forever but due to changes on my end or chrome's I have never found another app that did this successfully. So the problem is I have to manually turn on or off for individual videos.
Finally an app that lets me utilize my ultra wide monitor.
didn't work at all
Works as it says. Perfect video output on my 34" ultrwide (21:9). Thank you for the great extension!
It just doesn't work with key combinations. I really don't know how it can have such good reviews. I've been using it for a couple of months since my last one stopped working after and update and this one just never works. No doubt the worst I tried for the purpose.
Not working for Showtime
This extension works wayy better than "Ultrawidify" and the UI is wayyyy better. I use this on a 16:10 aspect ratio and it works perfectly!
Hey, This is working great except i cant set any shortcuts or the shortcut thats listed with it doesnt work. So is there anything i can do about it?
