In PowerPoint for Windows, macOS, and web, you can add closed captions or subtitles to videos and audio files in your presentations. Adding closed captions makes your presentation accessible to a larger audience, including people with hearing disabilities and those who speak languages other than the one in your video.
To read about best practices for accessibility, see Make your PowerPoint presentations accessible to people with disabilities.
Beginning with version 2016, PowerPoint has a new, simpler format for caption files, called WebVTT. The video player in the following versions of PowerPoint can show those captions when you play the video:
-
PowerPoint 2016
-
PowerPoint 2019
-
PowerPoint 2021
-
PowerPoint for Microsoft 365
The closed captions are stored in a text-based file with a .vtt filename extension. You can create a closed caption file on your own or use a caption-creation tool. To search online for available tools and detailed instructions, type "create vtt file" in your search engine.
For instructions on showing captions when watching a video in these versions of PowerPoint, see Accessibility features in video and audio playback on PowerPoint.
Requirements for this feature
In Office 2016, the availability of the closed-captioning feature depends on the way Microsoft 365 was installed. Closed-captioning is only available for Office 2016 Click-to-Run installations; MSI-based installations don't have closed-captioning features. Read the next section to see whether the feature is available to your installation of PowerPoint 2016.
-
Open an Office 2016 application.
-
On the File menu, select Account.
-
For Office 2016 Click-to-Run installations, you'll have an Update Options button.
MSI-based installations don't have an Update Options button. You'll only see the About <application name> button.
If you have an MSI-based installation of Office 2016, refer to the Office 2010-2013 tab of this article to see what captioning features are available to you.
