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.

No longer works on Netflix, too bad
Hey dev, it is not working. Can you guide how to use it via tutorial video? Will wait for your response.
works but is VERY janky ... took 10 mins to get to work on disney + and theres a weird nack to get it working
Does exactly what it's supposed to do and does it well.
Phenomenal extension, works great for adjusting widescreen content to fit 16:10 screens, or for removing embedded black bars in 4:3 content for use on an old tube TV. Works perfectly on YouTube. Works on Prime Video and Disney+ too. Not tested Netflix. Doesn't seem to work on BBC iPlayer though, not sure why. That's the only reason I've deducted a star, because it claims to work on all embedded video. Idk what makes iPlayer different. Otherwise, this is a true must-have for anyone with a display that isn't 16:9. If I hadn't tried iPlayer, it would be a very easy 5 stars.
Отличное приложение, делает кроп как для 4:3 так и для 5:4, а большего мне и не надо, авторам огромное спасибо за предоставление такого решения для моей проблемы!
Tengo mucho tiempo buscando una aplicación que permita que YouTube se vea en pantalla completa sin bordes negros y esta es la unica que ha cumplido con la tarea muy facil ya viene configurada solo usar. Mis felicitaciones a los desarrolladores
finally my search is over, proper ultrawidescreen on all videos however I choose
Careful: After some back and forth testing I figured that this extension alone consistently lowers my speedometer results by about 5-10% and also uses an odd amount of RAM when enabled despite no video is running, I don't know whats going on here but I immediately uninstalled.
This is perfect for fixing kiwi browser's youtube full screen bug.
