Presenting and Sharing in a Web Conference

To give a presentation in BBB, you need presentation rights. You can either be given presentation rights by the organiser of the web conference or, in the event you have moderation rights, you can assign presentation rights yourself by clicking on your name in the user list and selecting „Become a presenter“. Here, it should be noted that only one participant can present at any one time.

Uploading a presentation

You can upload MS Office or PDF files by clicking the plus button.


If several presentations have been uploaded, you can change the current presentation by clicking the plus button.


Note that BBB automatically converts any files to PDF files. This means that any file-specific formatting and fonts as well as animations and embedded content may be lost. Therefore, it is recommended to convert files to PDF files prior to uploading them by using the programme in which they were created.

Screen Sharing

By clicking on the presentation icon, you can share your screen, a window or a browser tab.


You can transmit audio by selecting “Share system audio”.

Creating polls

There are several ways of creating a poll. You can launch a quick poll on a presentation if the current slide contains a question mark and a numbered or alphabetical list.


A survey with answer choices A,B and C will then be displayed. You can close the poll and publish its results by clicking on “Publish poll”.

Moreover, you can create a poll, which is not associated to a presentation, by clicking the plus button.


You can then enter your question and select your preferred response type. For example, selecting “User response” allows participants to answer a question by entering a maximum of 45 characters. In addition, you have the option to make a poll anonymous. With this option, you will not be able to view who voted for which answer choice.

Other presentation tools

You can use the toolbar on the right to annotate slides by using, for example, a pen or text input. The toolbar at the bottom right can be used to zoom in on slides or adjust the aspect ratio.

Sharing an external video

You can share an external video from YouTube or Vimeo by clicking on the plus button. Videos from the TU Clausthal video server are currently not supported. An exception are videos which are uploaded with an additional option: Einbinden eines Videos vom Video-Server in BigBlueButton
