Description from store
Need to remove unnecessary black bars from this youtube video you're watching? Ultrawidify is here for you.
🌟🌟🌟 TL;DR 🌟🌟🌟
⚠️ Features automatic aspect ratio detection (some sites do NOT allow this feature)
✅ Works on youtube and twitch. It may also work on other sites, but support of other sites is not guaranteed.
↔️ Supports both cropping and stretching
✅ Works with youtube theater mode
✅ In-player UI, because you can't really use extension popup while in full screen
❓ How do I use it?
If the site does not utilize DRM, you can just sit back and let autodetection handle everything for you. On sites that use DRM — or on videos where autodetection proves unreliable — you can either use the extension popup or the keyboard shortcuts (note that extension shortcuts do not override site's default shortcuts) to set the aspect ratio manually.
💬 Features in detail 💬
1️⃣ Automatic aspect ratio detection
This feature ensures that video will be cropped without you having to lift a finger. It runs continuously and will even detect aspect ratio changes that happen in the middle of the video.
While autodetection should work fine on most of the videos, it is not 100% accurate and has some limitations:
◾ The extension may struggle with dark frames (especially the ones that contain text)
◾ Autodetection may cause high CPU usage (especially on older CPUs)
◾ It may not be able to keep up with rapid aspect ratio changes
◾ It cannot work on sites that utilize DRM protection schemes (e.g. Netflix, Disney+) — you will have to adjust aspect ratio manually on those.
Certain aspect ratio detection parameters can be tweaked in the extension settings. You can increase (or decrease) the frequency of aspect ratio checking. It is also possible to increase the level of certainty that's required for extension to change the crop.
2️⃣ Manual aspect ratio correction
For sites that do not support automatic aspect ratio detection, Ultrawidify allows you to manually crop the video. The extension allows you to crop to these aspect ratios by default:
→ Fit Width (shortcut: W)
→ Fit Height (shortcut: E)
→ 21:9 (shortcut: D)
→ 18:9 (or 2:1; shortcut: X)
→ 16:9 (shortcut: S)
You can also reset the aspect ratio back to the initial aspect ratio (shortcut: R).
Note that some sites may define keyboard shortcuts that interfere with the shortcuts defined by this extension. In such cases, the shortcuts defined by this extension may not work.
3️⃣ Stretch the video
You paid for the entire monitor, so you're gonna use all the monitor — even if it means stretching the video into complete garbage? Ultrawidify's got you covered with a bunch of different options:
→ Don't: for men of culture
→ Basic: for people who just don't care, at all. (This option does not remove the black bars)
→ Hybrid: crops the video first and then stretches the video to fill the remaining space
→Thin borders — only stretch the video if the black borders are _really_ thin
→ 4:3 (src) — not all people are men of culture. Some people torture others by posting 4:3 content stretched to 16:9. This option makes the video 4:3 again.
→ 16:9 (src) — ensures that the video is stretched (or squeezed) to 16:9.

- (2025-02-14) 오누르에라이: Great Extension, but Currently Completely Broken I've been using Ultrawidify for years, and it's been an essential extension for my setup. However, since the recent update, it's become very buggy, and as of today, it has completely stopped working. • Nothing functions anymore – autodetection, shortcuts, and even manual settings adjustments don’t work. • Settings are broken – If I try to change an option, it doesn’t apply properly. Sometimes it only updates visually but doesn't take effect. • UI scaling issues – The quick settings UI has been displaying incorrectly for months now. I appreciate this extension and hope these issues get fixed soon! Also, I’d love to see a Discord server for reporting bugs, contributing, and making feature suggestions, as some other extensions have. Looking forward to future updates!
- (2023-08-20) leonardo guimaraes: o melhor até agora , só para configurar q poderia ser mais prático ou traduzido
- (2023-07-14) Jonathan Ramirez: Great for watching anime, use hybrid stretch setting to make everything fit perfectly in a 21;9 aspect ratio at 3440 x 1440
- (2023-07-06) Mad K: Merciiiiiiiiiiiiiiiiiiiiiiiii !
- (2023-06-19) Vic Queiroz: Muito bom, mas pra quem utiliza o Wix precisa desabilitar que buga algumas coisas dentro do Editor.
- (2023-06-02) Jordan Bateman: Works most of the time, but sometimes it just stretches and widens the video and even still leaves black bars. Even with stretch option turned off. It should only crop out the black bars and not widen the video. eg: The 2.35:1 GTA V trailers on youtube
- (2023-04-09) Risky: This extension causes the problem in the following reddit post: https://www.reddit.com/r/chrome/comments/12eqt27/help_needed_with_missing_google_search_features/
- (2023-03-14) Kay V: работает убирает черные полосы, растягиваю видео uniwersal video maximazer, но автоматчески не срабатывает как это задумано, ножно каждый раз через меню делать
- (2023-02-15) Ambrus Török: Only working extension I have come across so far. Good: - Gives useful error messages. Bad: - A bit complex UI, but I don't mint it because it gives you plenty of options.
- (2023-02-13) Christian: I had a bug on Netflix where when I went into full screen mode, my movie/show would be stretched out. It was annoying me so I did a search on reddit which brought me to here. This program told me what was wrong (it was a hardware acceleration issue and I had to select a different GPU processing engine or something) So though I didnt use the product for what it was mainly intended for, it did diagnose the problem and pretty much resolved it.
- (2023-01-23) Mattia Mossenta: They gave me the fix for wrong aspect ratio, even with other extensions for ultawide. Thanks for the info about chrome://flags#use-angle
- (2023-01-19) 7h07h: No longer resizes height, so instead of removing black bars, it just stretches the width.
- (2022-10-01) Tobias Hungwe: I was shocked it got so little remarks, great work!
- (2022-08-25) Sathianphong Phongsathian: test some video on youtube with originally 4:3 but uploaded as 16:9, use 4:3 stretch (src) mode, working great when not fullscreen. i have to press f (toggle fullscreen) multiple times to make it work in fullscreen mode tho, quite inconsistency for now
- (2022-08-15) Liquid Rider: For a while this extension was unmatched. Whether it was a recent update on Chrome's end or theirs, the app has become unbearable to work with. Constantly freezing, unable to select settings. Installed reinstalled, even tried using Edge and the same issue occurred. Uninstalling for now, but will check back later.
- (2022-07-26) Thomas Lundy: It just zooms in, so you lose content. I'd presume it would resize the video player, but I guess not. Why bother lose content? I'd rather black bars than missing out on content in the video.
- (2022-07-17) Edi: Thank you. Works as I wanted.
- (2022-06-04) Tim Hutt: Doesn't seem to do anything at all on Prime Video (UK) unfortunately.
- (2022-04-29) Ashton Humby: doesn't work with a curved monitor
- (2022-04-27) Tei Ama: На некоторых сайтах смещает картинку вправо на 20% (
- (2022-04-10) Michael Wozzeck: It used to be bad now it is amazing and I can't live without it thanks for the auto-detection it's so good your work is under appreciated thanks man!
- (2022-04-07) Maximilian Teschner: doesnt work
- (2022-04-06) Fredy Guzman: it does the job
- (2022-03-16) iRokr: Unfortunately, this caused issues with viewing Reddit videos. Switch to the Zoom to Fill which doesn't seem to have an issue.
- (2022-02-22) Benjamin Ehambaram: Doesnt work
- (2022-02-21) Gnydr Cook: How I wish Ultrawidify was the first Chrome Extension to appear when I searched for ways to get rid of black bars when watching Netflix. This extension is like the easy plug-and-play setup. I only needed to add it and boom! It does its magic perfectly! Thanks to the brains behind this very helpful program.
- (2021-12-28) Ammon Marstella: doesn't work
- (2021-12-25) 中村巌(RU245): Works like a charm! 21:9
- (2021-12-20) Aberraton: The auto detection is beautiful sometimes wrongfully detects but very rarely trust I can't live without this it works so well with movies and such has made my viewing experience a dream. One thing I think people forget this is a free extension. Thank you Tamius Han you're an angel
- (2021-12-18) Etherpixel56: works so far .....just what i needed to get rid of em horrible black borders , shouldve used this ALOT earlier, keep it up @dev
- (2021-12-17) Sam Woolf: works
- (2021-12-12) Walter Monzon: It does not work. Crops too much.
- (2021-11-30) Adrian Black: Funciona de manera automática, se ajusta a la ventana y a las pantallas ultra wide, totalmente recomendado
- (2021-11-17) Joseph Thaidigsman: I've used around 10 different widescreen extensions and this one is by far the best. No bugs and it constantly reevaluates videos to stretch them appropriately without any user input. Greatly appreciated.
- (2021-09-21) Anthraxxis: How I didn't think to look for something like this sooner, I don't know. But either way, this works like a charm for me, and better than a couple others I tried. Couldn't ask for more.
- (2021-09-13) Sean Krinsky: No longer works with HBO Max. Screen gets shifted to the right.
- (2021-08-23) Vincent Wendén: Doesnt work on Disney plus or Netflix
- (2021-08-17) Mark Rai: Great app, everything works. Automatically switches from 16 * 9 to 21 * 9 and vice versa. The main thing is to familiarize yourself with the settings and configure the application correctly, otherwise it will not work correctly in certain situations. P.S.All video after adjustment is stretched by itself. Anyone who gives bad grades is just stupid. Отличное приложение, все работает. Автоматически переключается с 16*9 на 21*9 и обратно. Главное ознакомитесь с настройками и правильно настройте приложение, иначе оно будет не корректно работать в определенных ситуациях. Все видео после настройки растягивает сам. Кто ставит плохие оценки просто глуп.
- (2021-08-08) Dennis Vc: Only extension that works as supposed to 32:10 monitor.
- (2021-08-05) Michelle Leynes: Until I find a better app, I don't think I'd ever have it any other way other than ultrawidify. At first I thought this app wasn't working because the configuration seemed a bit complicated, however after I got it to work, watching videos on my 34" monitor has been a D R E A M. My gripe with several other display configuration app catered to those blessed with the ultrawide curse that is black bars, most apps stretch it out in a certain way that erases some of the video in the corners as it's just zoomed in. But hybrid mode has been a God send as it's not overly and obviously stretched out, I truly feel immersed watching youtube and streaming site videos. I have not tried Twitch or Facebook videos yet, so I cannot vouch for those. However thank you so much for such an amazing application, you saved my eyeballs!
- (2021-07-13) DeadWolf: perfeita, muito facil de usar e resolve o problema
- (2021-06-11) Nova Company: 21 век на дворе а я должен постоянно каждое видео настраивать,сразу нельзя сделать чтобы он ВСЕ видео растягивал? помойка!!!!!!!!!!!!!!!!!!!!

- (2021-05-13) Nikhil Sikka: It DOESN'T work, at all. Tried on latest chrome on Disney, Youtube and netflix and amazon prime. It's just a fancy extension with a lot of fancy options that do absolutely nothing
- (2021-05-13) Unmesh Gaikwad: Does what it says was searching for one so bad this works like a charm even in fullscreen for 21:9 Thanx Mate 👍
- (2021-04-18) himansu nayak: Didnt work well on the LG 49wl95c-we 49 inch screen monitor
