PowerPoint Checklist (for Presenters)

Criteria and guidelines in checklist form for preparing and uploading your PowerPoint into your ON24 webcast.

As you prepare for your live webcast, it’s important to make sure your PowerPoint presentation is set up correctly. To ensure your PowerPoint uploads and converts properly, please review the criteria below and verify your PowerPoint meets these requirements before uploading it to your webcast.

As a best practice, we recommend uploading your PowerPoint at least 24 - 48 hours prior to the live event.

Your PowerPoint slide deck should be saved in a PPT or PPTX format, and should not exceed 50Mb in size.

Video Tutorial: 

If your PowerPoint does not upload as expected, immediately submit a case for technical support and attach your slide deck to the case.  Please do not continue to attempt to upload your PowerPoint as this will exacerbate the issue and prolong the time it takes to reach a resolution.
