IINA is born to be a modern macOS application, from its framework to the user interface. It adopts the post-Yosemite design language of macOS and keeps up the pace of new technologies like Force Touch, Touch Bar, and Picture-in-Picture.
Powered by the open source media player mpv, IINA can play almost every media file you have. With the support of youtube-dl and our browser extensions, you can also play a variety of online streams in IINA via one click.
Written in the Swift programming language, IINA is free and open-sourced under the GPLv3 license. Please feel free to contribute to it by opening an issue, sending a feature request or a bug report on GitHub or by email.
IINA has been translated into more than 20 languages by translators from all over the world. You can improve the translation or add your new language freely via our translation platform (powered by Crowdin).
