If you will be without an Internet connection only temporarily, a good option would be downloading the videos on the Khan Academy app so that you can watch them while you're offline! Here's how to do it both on iOS and Android:
Android app
1. Run the Khan Academy Android app and go to the video you'd like to access offline.
2. Tap the Bookmark icon in the upper right-hand corner of the screen. The video will be added to your bookmarks.
3. Go to your bookmarks—the Bookmark icon in the navigation bar—and tap the download button to download the video.
If you'd like to customize your download settings (e.g., downloading videos in HD quality), tap Download settings.
iOS app
1. Run the Khan Academy iOS app and go to the video you'd like to access offline.
2. Tap the Bookmark icon in the upper right-hand corner of the screen. The video will be added to your bookmarks.
3. Go to your bookmarks—the Bookmark icon in your homescreen—and tap the download button to download the video.
If you'd like to customize your download settings (e.g., downloading videos in HD quality), tap Download settings.
Disconnected environments
If you need to use Khan Academy in an environment permanently disconnected, we recommend using Kolibri: an unofficial volunteer-driven initiative to provide a version of the Khan Academy videos and exercises that works offline. Running Kolibri as a local server, you can watch Khan Academy videos and complete exercises - all without needing an internet connection!
Kolibri is a new open-source learning platform that replaces the previous Khan Academy Lite (KA Lite). If you’re just getting started, we highly recommend using Kolibri instead of KA Lite because it supports more content and will receive regular updates, and more ongoing support.
