TED talks are not available to be downloaded from TED.com.
Instead, we recommend using the download function on the free TED app for iOS and Android mobile devices. This function allows you to download an offline copy of the video locally on your device the same way as other streaming services (i.e. the file is only usable within the environment of the app). Please note that you will need to create a free TED.com account in order to use the download function.
Downloading a video on the TED app:
1. Visit a talk page.
2. Tap the "down arrow" icon."
3. The arrow will become a download progress circle. You can stop the download by tapping the X.
A blue banner at the bottom will show the download percentage.
4. The circle becomes a checkmark when the download is complete. You can tap the checkmark to delete the download.
6. You can find your download (and also track its progress or delete it) in the Downloads folder of the Profile tab.
If you cannot download a video when not connected to WiFi, please make sure that your TED app and/or your device is set to allow downloads while using cellular data.
If you're still having any trouble downloading a video, or playing a download offline, please reach out to us at contact@ted.com with as much detail as possible about the problem.
