The cross-browser extension that manipulates video aspect ratio to fit your entire screen.
đź‘‹ Introduction
Proven to be working on all major video streaming platforms. If it doesn't work for you, it could be a OS related bug. I am using macOS and before I make claims, I thoroughly test it through all major browsers.
🚀 Features
The only extension on the market with functionalities that no other extension in this category possess.

▸ Blazingly fast — injection script that manipulates the video is written in plain JavaScript, has tiny footprint and is very fast.
▸ Limitless platforms — not limited to any specific video streaming platform. Aims to work everywhere, including embeddable videos.
▸ Minimal interface — thoughtful design that doesn't get in your way, but provides you with all the necessary options to get the experience you deserve.
▸ Appearance — automatically applies the appearance that you are using as your system preference. If your system is in dark mode, the extension will be too.
▸ Cross-browser — available for all major browsers and tested on Chrome & Firefox. It works in all Chromium based browsers as well.
▸ Internationalization — supports handful of languages, but aiming to support all major languages with the help of the community.
▸ Keyboard shortcuts — customizable within the browser to avoid conflicts with other extensions. Support for activity and mode toggling.
▸ Magic touch — Toggle between modes with built-in pinch inwards/outwards on touch screens, trackpads with multi-touch gestures and mouse wheel while holding CTRL key.
🧠Purpose
Gain power over the video in fullscreen mode. Primarily developed for 34" ultra-wide screens, but powerful for other smaller or larger screens too. I am currently using it on my Macbook Pro 14" to get rid of all black bars (horizontally and vertically), previously I used it on ultra-wide monitor.
🙋‍♂️ Usage
Relatively easy to use, but powerful at its core. Comes with handful of options within small interface and keyboard shortcuts.
▸ Interface – Popup interface that you usually open by clicking on the extension icon, has built-in shortcut to toggle it for an easy access at your fingertips.
▸ Activity – This option will be enabled by default. To deactivate the features it applies to the video element, toggle the switch.
▸ Mode – Upscale mode will be enabled by default and only one mode can be active at a time.
▸ Scale – It works simultaneously with the active mode and can scale the video up or down. The default value is 1 and it means that no scaling will be applied.
🤞 Claims
It is working on all globally popular video streaming platforms. Including all embeddable videos. If it doesn't work somewhere, open up a ticket on the support link that's provided (Github Issues) and I'll try to fix it for you and everybody else.
