About file presentation

File presentation lets you upload files and share them in a meeting. Your meeting account includes a cloud-based file library that you can access from your own meeting room and anyone else's meeting room. (Your files stay with you, not the meeting room.) Guests can't share files without a meeting account.

When you share a file or video, everyone can follow along on their computers and their Android smartphones or iOS devices. The meeting stage shows you what you are sharing and displays presentation controls. The meeting host (and co-hosts), presenters, and the person sharing the file can navigate in the file using the presentation controls.

Note: You can't share a file from the mobile apps. If you're a co-host or presenter in the meeting, you can use the presentation controls to help navigate the file or video.

Anyone can share their screen, an application window, a whiteboard, or a file within the meeting, without being promoted. If you'd like, you can restrict sharing in your meeting room to only yourself and presenters. Turning off open sharing requires the host to promote a guest to the Presenter role before they can share a file.

Upload and share files

You can upload an Adobe PDF, Word document, PowerPoint presentation, Excel spreadsheet, or video to your file library and present it in your meeting. Video files are limited to 1 GB; all other files are limited to 200 MB.

Audio and image files are not supported; slide transitions, animations, and embedded audio/video in PowerPoint presentations are not supported. For supported file formats and details, see File and Video Sharing. If you need to share a file that is not supported, share your screen instead.

To avoid delays during your meeting, jump into your meeting room early, and upload files to your library. We strongly recommend that you upload videos that you plan to share in advance, as videos often take longer to upload than documents. All files you upload are available in your file library; they never expire.

To upload a file or view your file library, in the meeting controls, click the Share button, and then select File Presentation.


Use the presentation controls

If you are the meeting host, co-host, presenter, or the person sharing the file, controls let you manage the presentation.

While you share a:

  • File - use the presentation controls to page through the document or file.
  • PowerPoint slide deck - click the Notes button to show the PowerPoint notes (if available). Click the button again to hide them.
  • Video - use the player controls to play or pause the video, adjust the playback volume on your device, and skip to specific timestamps in the video.

View a shared file

When you or someone is sharing a file, you can zoom in and out or set the display at a precise percentage. You can also maximize the view or use full-stage mode to control how much of the screen area is used for shared content. Both the full-stage and maximize view hide the meeting sidebar and meeting top bar. The meeting controls reappear when you point to the meeting stage. Either full-stage view or maximized view can be used but not at the same time.

Click the Full-Stage button to expand the shared content to fill the meeting window without taking up the whole screen. Click the button again to reset your view.


Click the Maximize button to enter full-screen mode. Click the button again to reset your view.


View a shared video

The video audio plays from your device's main speakers. This means it plays using your computer's speakers when using the desktop app or a web browser on your computer even if you dial in to the meeting or have the meeting call you. If you are only connected to the meeting using your phone and not in the meeting room, you will not hear the video's audio. If you are using the mobile app to view a video being shared, you must connect to the meeting using VoIP to hear the video.

Video streams in the meeting room at 1080p, 720p, or 480p depending on your internet connection. You can't manually select your resolution. If you are on a low-bandwidth connection, your video stream may require time to buffer and lag.
