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.

The interface is clean and minimal, yet the extension gives me full control over how I view videos. The keyboard shortcuts are super helpful, and I love how it adapts to my dark mode automatically. 10/10
Videolarda filigran bırakıyor.. ekranın altında simgesini sabit olarak bırakıyo.. Pro versiyonunu alayım dedim ama yıllık 30 dolar ile ücretlendirmişler.. Hem bu kadar pahalı hemde yaptığı pek bişey yokken bu kadar pahalı ve sınırsız kullanıma açıkl olmaması yüzünden notum sıfır..
Nice extension. A shame about the watermark, but you can remove that pretty easily. What a world we live in, where media distribution giants have the worst video players. They're so bad that we have to purchase 3rd party applications to just ... gasp .... fullscreen a video.
Really love this extension, it's perfect for my OLED UW screen. Edit: Thank you for listening to us and removing the watermark <3 :)
UltraWideo is/has been an excellent extension, but the latest update introduces a questionable subscription model. The additional features on offer struggle to justify $30/year, and the introduction of a watermark for free users is sure to disappoint devoted fans. It's an unusual move from an otherwise rational developer. I expect an increasingly poor reception to these changes as time goes on.
This is an amazing extension, but please remove the logo from the bottom corner of the screen. Thanks
please remove the box in the center of screen after use hotkey to resize video. it small but annoying
Теперь всё супер!!!
Doesn't work at all for YouTube with Edge
Endlich ein Upscaler, der auch die mobile Version von Youtube erkennt. Nutze das zusammen mit einen User Agent Switcher, da mein altes Surface Go 2 im Jahre 2025 die Desktop-Version von Youtube nicht stemmen kann und mir die schwarzen Balken auf dem 3:2 Display zu groß waren.
