To upload a PowerPoint presentation to the Internet, create a free account on SlideShare.net, and use the upload functionality on the website to save the presentation to your SlideShare account. Alternatively, use a cloud storage service such as Google Drive to upload the presentation.
Navigate to SlideShare.net, click the Signup button, type your email address, choose a username and password, and click Signup. If you have an existing LinkedIn or Facebook account, use it to sign in instead. Once you sign in, click the Upload button in the navigation bar. Select the Public option if you wish to share the presentation with others. After clicking Upload, select the presentation, and add information to the Title, Tags, Category and Description fields to complete the process. If the font or images on the presentation get corrupted, convert the presentation to a PDF format before uploading it. As of 2015, SlideShare.net supports multiple PowerPoint formats, including PPT, PPS, PPTX and PPSX.
To upload a presentation to a cloud storage service, navigate to the Google Drive website, and log in with your Google account. Click the New button, select the File Upload option, select the PowerPoint presentation, and click Open. If using Google Chrome or Firefox, click on the presentation, and drag it into Google Drive to upload it.
