CloudApp has three different link types: share, direct and download.
1. Share links: https://cl.ly/2J0j2W1E2i3N
Use a share link when you would like to have an easily viewable page to access the file or image. These also auto-expand/unfurl in apps like Slack and HipChat to display a smaller version of the file in-line.
Direct links are used to access a file directly and bypass the viewer page. You can use them to paste an image directly into an HTML code of your web page.
Download links are helpful when you want a link to automatically trigger a download and save to the user’s computer.
